Buy the Rado DiaStar Original Skeleton if you want the more distinctive open-worked design, Ceramos bezel, explicitly documented skeleton movement and five-year warranty, and are comfortable spending roughly the mid-$2,000s. Buy the Tissot PRX Powermatic 80 Skeleton if you prefer a slimmer 1970s integrated-bracelet shape and a lower entry price. Both documented platforms are Swiss automatic watches with an 80-hour power reserve, but the comparison is not perfectly symmetrical: official Tissot pages currently document the PRX Powermatic 80 40 mm platform rather than a page clearly identified as the skeleton reference. Confirm the exact Tissot reference, dial treatment and regional price before paying.
Which watch is the better buy?
The Rado is the stronger choice for a buyer who treats the skeletonized movement and case materials as the main event. Its 38 mm DiaStar case, faceted oval profile, Ceramos bezel and published R808 specifications give it a more individual identity than the familiar sports-watch silhouette of the PRX. Rado also publishes a five-position test and a five-year warranty.

The documented PRX Powermatic 80 platform is 40 mm wide but only 10.93 mm thick, uses an integrated steel bracelet and carries a 100 m water-resistance rating. US examples of the standard platform are listed at $850 and $950, well below documented Rado pricing, although those figures are not a confirmed price for the skeleton edition.
In practical terms, choose the Rado for a statement skeleton watch and the Tissot for a more restrained everyday sports watch. The final decision should be made from the exact reference sold in your country, not from a generic product name.

What makes the Rado DiaStar Original Skeleton different?
Rado builds the watch around its DiaStar identity rather than disguising a conventional round sports watch as a skeleton. The case is 38 mm in diameter, with a faceted, elongated profile and an 11.9 mm thickness. The Ceramos bezel is the visual signature: it combines a ceramic-metal material treatment with a hard, reflective surface that frames the open dial.

The current R12166159 listing adds a black skeleton dial, Super-LumiNova details, transparent sapphire caseback and an 80 g weight for its rubber-strap configuration. The US R12162153 listing uses the steel bracelet and weighs 133 g.
Rado’s autumn 2026 releases add yellow-gold-coloured and rose-gold-coloured Ceramos bezel treatments with matching rubber straps. Those models use the EasyClip strap-change system, so the strap can be exchanged without tools, but compatibility still depends on the exact case and connector reference. Rado’s own launch language—“If we can imagine it, we can make it. And if we can make it, we will.”—accurately describes the watch’s emphasis on material and form.
How readable is the Rado’s skeleton dial?
Skeleton watches trade some dial contrast for a view of the bridges, wheels and balance. The Rado retains Super-LumiNova details, but the dark open-worked background can still be less instantly legible than a solid dial in dim or busy conditions. If you read the time at a glance more often than you admire the movement, try the watch on your wrist and check the hands against both bright and low-light backgrounds.
What does the Rado’s five-position test mean?
Rado states that the R808 is tested in five positions. That is a regulation claim about how the movement is checked in different orientations; it is not a guarantee that every wearer will see chronometer-level accuracy. It does, however, provide more published information about adjustment than the Tissot platform pages cited here.

What is actually documented about the Tissot PRX Powermatic 80 Skeleton?
The official Tissot pages available for this comparison describe the PRX Powermatic 80 40 mm platform. They specify a 40.0 mm width, 39.5 mm length, 10.93 mm thickness, a 316L stainless-steel case, sapphire crystal with anti-reflective coating, a see-through caseback, a Swiss automatic movement, a Nivachron balance spring, an 80-hour power reserve, 100 m water resistance and a quick-release integrated bracelet.
Those pages do not clearly identify the current skeleton reference, its reference number, the exact bridge and rotor decoration, its weight or its regional list price. Therefore, do not assume that every specification of a standard PRX 40 mm applies unchanged to the skeleton model. A retailer photograph may show an open-worked dial, but the warranty card and caseback reference are what establish which watch you are actually buying.
Why the PRX shape appeals to everyday wearers
The PRX uses the integrated-bracelet language associated with 1970s sports watches: the bracelet flows directly from the case, the lugs are visually minimized and the profile is comparatively thin. Tissot describes it as a “slim, smooth watch with an authentic ’70s feel.” Its 40 mm width gives more wrist presence than the Rado’s 38 mm, while the 10.93 mm platform thickness can slide under a cuff more easily.
The trade-off is a less individualized silhouette. The PRX’s appeal comes from proportion and continuity between case and bracelet, not from the sculptural, faceted identity of the DiaStar. Whether that is an advantage depends on whether you want the skeleton mechanism to dominate the look or to sit inside a familiar daily-wear design.
How do the skeleton movements compare?
Both documented platforms offer an 80-hour reserve, enough to leave the watch off for a long weekend and put it back on still running. That shared reserve removes one common reason to choose one over the other; the more meaningful difference is how much each brand documents and exposes the mechanism.
| Movement question | Rado R808 | Tissot PRX Powermatic 80 platform |
|---|---|---|
| Is skeletonization explicitly documented? | Yes; Rado identifies the calibre as skeletonized and shows an open-worked dial | The exact skeleton architecture is not established by the cited official pages |
| Power reserve | 80 hours | 80 hours |
| Anti-magnetic element | Nivachron hairspring | Nivachron balance spring |
| Position testing | Five-position testing is published | Not stated on the cited pages |
| Additional figures | Autumn references are reported with 25 jewels and 21,600 vibrations per hour | Not established for the skeleton reference |
The Rado is the safer choice if movement visibility is your primary reason for buying a skeleton watch because the manufacturer explicitly identifies the R808 as skeletonized. With the Tissot, inspect the actual dial side and caseback: some “skeleton” executions reveal only selected areas, while others remove much more of the dial and add decorative bridges. The visual amount of open-work can change legibility and perceived value even when the power reserve is identical.

Which watch wears better on a real wrist?
Start with dimensions, then account for the bracelet or strap. The Rado is 38.0 mm wide and 11.9 mm thick. The documented Tissot platform is 40.0 mm wide, 39.5 mm long and 10.93 mm thick. On a small or medium wrist, the Rado’s narrower diameter can look more balanced, while the PRX’s shorter stated length and integrated bracelet can keep its ends from overhanging. On a larger wrist, the Tissot’s extra 2 mm creates a clearer sports-watch presence.
Bracelet, rubber and weight
- The steel Rado reference weighs 133 g, so it feels substantial and planted.
- The rubber-strap Rado reference weighs 80 g, making it considerably lighter and more casual.
- The PRX platform uses an integrated steel bracelet with quick release. Skeleton-specific weight and the exact bracelet construction remain to be confirmed.
- Rado’s autumn EasyClip system is useful for changing straps, but check that the replacement strap is made for your exact reference.
An integrated bracelet is less forgiving than a conventional lug design: you cannot substitute any generic 20 mm strap. Before ordering a PRX strap, verify the model number and connector shape. The same principle applies to Rado EasyClip accessories.

Monochrome reports 100 m water resistance for the autumn Rado references, and the official PRX platform pages list 100 m. That rating supports ordinary exposure such as rain and surface swimming when the watch is in good condition, but it is not permission to operate the crown underwater or to ignore gasket aging. Have seals checked during service, particularly if the watch is used in salt water or frequently exposed to heat and soap.
Are Ceramos and 316L steel materially different?
Rado’s Ceramos bezel is the material story: it gives the DiaStar a ceramic-metal treatment and a highly faceted, scratch-resistant-looking surface, while the case combines stainless steel and PVD elements. Sapphire crystals protect the front and back. This combination is intended to make the bezel as important to the design as the movement.
The documented Tissot uses a conventional 316L stainless-steel case with sapphire crystal and anti-reflective coating. Stainless steel is familiar, serviceable and visually adaptable, but it does not create the same distinctive bezel effect. The PRX’s durability advantage is not established; both watches still depend on crystal condition, bracelet wear, gasket maintenance and careful servicing.
Neither material makes the watch damage-proof. A hard impact can chip a ceramic-based bezel or scratch a polished steel surface, and replacing a proprietary bezel or integrated bracelet section can cost more than replacing a standard strap. Ask an authorized service center for current part availability before treating either watch as a carefree sports instrument.

How much do they cost, and what does the warranty cover?
Rado is materially more expensive in every documented market. The US steel-bracelet R12162153 is listed at $2,300. The UAE R12166159 listing is AED 11,100. Monochrome reports EUR 2,600/USD 2,700 for the autumn gold-coloured Ceramos references; those figures are market-specific and should be checked against the seller’s current price.
Tissot’s US pages list $850 for one steel PRX Powermatic 80 40 mm variant and $950 for a PVD variant. These are useful benchmarks for the platform, not a confirmed skeleton-edition MSRP. A skeleton model may carry a premium, and taxes, import costs and bracelet or strap configuration can change the final price in your country.
| After-sales item | Rado | Tissot |
|---|---|---|
| Published warranty in the cited listings | Five years | Two years |
| What to verify locally | Authorized service access, EasyClip connector and replacement bezel or bracelet availability | Exact skeleton reference, local warranty start date, integrated-bracelet links and quick-release strap compatibility |
The longer Rado warranty helps justify some of its premium, but warranty duration is only valuable if the seller is authorized and the terms cover your region. Keep the dated sales receipt, warranty card and reference number. For either watch, confirm return rights before removing protective film or sizing the bracelet.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which is better for everyday wear?
Choose the Rado when these priorities lead
- You want a skeletonized movement that the manufacturer explicitly identifies as such.
- You prefer a 38 mm, faceted case with a Ceramos bezel over a conventional round steel sports watch.
- You value the published five-position test and five-year warranty.
- You are comfortable paying around $2,300 in the US for the steel reference or equivalent regional pricing.
Choose the Tissot when these priorities lead
- You prefer the PRX’s integrated-bracelet, 1970s-inspired profile.
- You need a thinner documented platform at 10.93 mm and want a 100 m rating.
- You want to stay near the $850-$950 US price range of standard PRX Powermatic 80 variants, subject to the skeleton model’s actual price.
- You would rather wear a restrained sports watch than a highly assertive case-and-bezel design.
For office wear and mixed wardrobes, the Tissot’s smooth bracelet and thinner profile are easier to pair with ordinary clothing. For collectors who buy a watch for its personality, the Rado offers more visual and material separation from the rest of the market. Neither is automatically the better everyday watch: wrist size, tolerance for dial shimmer and access to local service matter more than the brand name.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
What should you verify before ordering?
- Record the exact reference. For Rado, distinguish R12162153 from R12166159 and confirm whether the package contains steel or rubber. For Tissot, do not accept a listing that says only “PRX Skeleton”; obtain the complete reference from the caseback or warranty card.
- Match the dimensions to your wrist. Measure a watch you already enjoy and compare its diameter, length and thickness with 38.0 × 45 × 11.9 mm for the reported Rado autumn references and 40.0 × 39.5 × 10.93 mm for the documented PRX platform.
- Inspect the movement side. Confirm how much of the bridges, rotor and balance is visible, whether the hands contrast with the background and whether the caseback is genuinely transparent.
- Confirm the delivered configuration. Check bracelet or strap, clasp, spare links, EasyClip or quick-release hardware and the stated weight. Product photographs can show a different configuration from the one in stock.
- Check regional commercial terms. Verify the tax-inclusive price, warranty duration, return window, water-resistance wording and whether the seller can provide authorized service in your country.
- Plan ownership costs. Ask about replacement bracelet links, proprietary straps, pressure testing and the expected service route before buying. A lower purchase price can be offset if imported parts or specialist service are difficult to obtain.
What are the main drawbacks of each watch?
| Watch | Limitations to accept |
|---|---|
| Rado DiaStar Original Skeleton | Higher price; thicker case than the documented PRX platform; skeleton dial may be less legible; steel and rubber references feel very different; proprietary Ceramos and EasyClip parts may cost more to replace. |
| Tissot PRX Powermatic 80 Skeleton | Exact skeleton reference, weight, movement decoration and MSRP require confirmation; integrated bracelet limits generic strap choices; two-year warranty is shorter; the design is less distinctive if you want a sculptural statement. |
These are not reasons to reject either watch. They identify the compromises that are easy to miss when a product photograph and an 80-hour reserve dominate the listing.
Final buying verdict
Pay the premium for the Rado if the watch’s identity comes from its open-worked R808, Ceramos bezel, compact 38 mm case and longer warranty. It is the more clearly documented skeleton proposition and the more individual design.

Choose the Tissot if the PRX silhouette, thinner platform and lower expected cost are the deciding factors. Before purchase, obtain the exact skeleton reference and verify its price and specifications on the Tissot site for your region; the currently documented $850 and $950 figures describe standard PRX Powermatic 80 variants, not a confirmed skeleton MSRP.
Frequently Asked Questions
Does an 80-hour power reserve mean I can leave either watch off for a weekend?
Yes. A fully wound automatic movement with an 80-hour reserve can normally run through a long weekend without being worn, although actual autonomy varies with winding efficiency and the watch’s condition. If it stops, reset the time rather than forcing the crown or shaking the watch aggressively.

Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Can I change the bracelets myself?
The Rado autumn references use the brand’s EasyClip system, while the documented PRX platform uses a quick-release integrated bracelet. Use only hardware made for the exact case reference; integrated connectors are not interchangeable with ordinary universal straps, and an incorrect spring bar can damage the case or release the watch.
What should I do if the skeleton dial is hard to read?
Compare the watch under office lighting, outdoors and at night before sizing the bracelet. Hand color, reflections from the sapphire and the contrast of the bridges can affect legibility more than the nominal case size, so a short wrist trial is more informative than a product photograph.
Does the five-position test make the Rado a chronometer?
No. Rado’s published five-position test indicates adjustment checks in multiple orientations, but it is not the same as an independent chronometer certification. Accuracy should be judged against the brand’s stated tolerance and your service center’s measurements.
