What exactly is the Tissot PRX Grendizer 50th Anniversary Edition?
The watch is reference T137.407.33.051.01, marketed by Tissot as the Tissot PRX UFO Robot Grendizer 50th Anniversary 40mm. It belongs to Tissot’s Classic Contemporary collection and was created in collaboration with Go Nagai.
Its appeal rests on three overlapping stories:
- Grendizer nostalgia: Tissot frames the release as a 50th-anniversary tribute to the character created in 1975.
- PRX design: the integrated-bracelet silhouette gives the collaboration a recognizably PRX form.
- Mechanical-watch substance: it uses Tissot’s Swiss automatic Powermatic 80 movement, sapphire crystal and a numbered caseback.
Design: a black PRX built around Grendizer
The tonneau-shaped case and stainless-steel bracelet have black PVD coating, giving the watch an all-black appearance. Tissot’s campaign describes the finish as part of this anniversary edition’s design.
The dial features a luminous sculpted Grendizer bust, rather than relying only on a logo or color reference. Tissot lists Super-LumiNova on the hands in its technical details; its campaign describes the sculpted dial motif as luminous.
The seconds hand is shaped as a reference to Grendizer’s Harken weapon and made from 18K gold. Tissot’s campaign also notes an engraving hidden inside the bezel, alongside the engraved rotor visible through the caseback.
A scratch-resistant sapphire crystal with anti-reflective coating on both sides protects the dial. Tissot lists the stainless-steel bracelet as interchangeable and quick-release. Its listed bracelet reference is T605051722; current replacement-part availability and third-party fitment have not been verified.
The presentation package is part of the release
Tissot describes a Spazer-inspired presentation capsule for the anniversary watch. The campaign also highlights drawings hand-signed by Go Nagai.
Rank #2
- 12 mm leather strap
- Designed to fit 12 mm lugs
- Stainless steel standard buckle
- Compatible with Tissot PRX watch models starting with T137410, T137407, T931407
The numbered watch, creator connection and UFO-inspired presentation are part of the edition’s collector appeal. For a pre-owned example, ask the seller what packaging, drawings and paperwork are included rather than assuming every listing contains a complete set.
The caseback is see-through and engraved, with an engraved rotor visible inside. Check clear photographs of the individual number and caseback when assessing a listing.

These are manufacturer-published specifications from Tissot’s U.S. product page; they are not independent test results.
Movement and everyday usability
The Powermatic 80 is the practical foundation of the watch. Tissot lists up to 80 hours of power reserve and a patented Nivachron balance spring. The manufacturer also lists a date function. The movement’s published specifications do not mean the watch is immune to magnetism, shocks or the need for servicing.
At 40mm wide and approximately 10.93mm thick, the watch has the dimensions Tissot lists for this PRX. The integrated bracelet can affect how a watch wears on an individual wrist, so fit remains personal. Tissot lists water resistance at 10 bar, or 100m / 330ft; seals and water resistance should be checked as appropriate over the watch’s service life.
The sapphire crystal is a useful specification for a watch intended to be worn. The black PVD finish is central to the model’s appearance, so take care to avoid impacts or abrasion that could mark the coating. Bracelet sizing and repairs are best handled by a competent watchmaker or Tissot service center.

How it relates to the 2024 Grendizer PRX
Tissot’s pressroom confirms that an earlier PRX Grendizer edition was released in 2024. The watch covered here is the black PVD 50th-anniversary reference T137.407.33.051.01, limited to 1,975 pieces. The available official research does not establish enough specifications for a reliable side-by-side comparison with the earlier edition.
Price and availability
Tissot’s official U.S. product page lists the price at $1,100 and states: “Sold Out – The PRX UFO ROBOT GRENDIZER 50th ANNIVERSARY will not be restocked.” Tissot’s U.K. campaign page lists £915.
These are official market-specific listed prices, not converted global prices or evidence of current stock. Tissot describes sales through selected points of sale and online in selected markets. The U.S. no-restock statement does not establish that every market or reseller is sold out. Check the relevant official market page or seller directly for current availability.
For readers looking for the Tissot PRX Grendizer 50th Anniversary reference T137.407.33.051.01, the secondary market may be an option. Treat each listing as a separate transaction. Verify the seller, return policy, authenticity process, warranty status, condition, individual number and included packaging. Current reseller inventory and completed transaction prices were not established in this research.

- Match the reference. Look for T137.407.33.051.01; do not assume another PRX Grendizer is the same watch.
- Request caseback photographs. Check that the see-through engraved back and rotor are shown clearly, and ask for a clear image of the individual number.
- Check paperwork and number. Ask for available documentation and compare it with the watch. A low number alone does not establish value.
- Confirm what is included. Ask specifically about the Spazer-inspired capsule, packaging, Go Nagai drawings, bracelet links, manuals and warranty card.
- Separate warranty from seller promises. Tissot lists a two-year warranty, but confirm whether it applies to the specific watch, is still valid and is transferable.
- Inspect the PVD coating. Ask for close-up images of bracelet edges, clasp, bezel and case corners so you can assess visible wear.
- Use protected payment and authentication. Prefer a seller or platform with a meaningful inspection or return process rather than relying only on stock images.
No reliable universal secondary-market valuation is established by the available research. An asking price is not a completed-sale price, and scarcity alone does not guarantee a resale premium.
Ownership and care
The watch does not require unusual maintenance simply because it is a collaboration, but its black PVD finish and limited status make avoidable damage frustrating. Store it so the bracelet does not rub against hard or abrasive objects, and keep any original packaging in a dry place.
Rank #4
- 12 mm leather strap
- Designed to fit 12 mm lugs

A soft watch travel case can be useful when transporting it, but it is optional and not confirmed here as part of Tissot’s package. A clean microfiber cloth is suitable for basic dust and fingerprint removal. Avoid abrasive polishing products that could alter the coating.
Have bracelet sizing done by a professional familiar with integrated bracelets and coated surfaces. Do not treat the 100-meter rating as a reason to skip suitable seal checks over time.

This PRX makes the most sense for a buyer who genuinely values Grendizer, the PRX design or limited mechanical watches. The sculpted dial and black finish make the collaboration distinctive without relying only on a logo.
It is less compelling for someone seeking the lowest-cost route into a Powermatic 80 PRX, a discreet everyday watch or a guaranteed investment. The collaboration, scarcity, presentation and anniversary story are part of its appeal, and a buyer should verify condition and completeness before paying a premium.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Verdict
The Tissot PRX UFO Robot Grendizer 50th Anniversary Special Edition ties its anniversary theme to a 1,975-piece production limit. The sculpted luminous dial motif, Harken-style seconds hand, black PVD case and engraved display-back rotor give it a distinct identity.
Tissot lists the U.S. price at $1,100 and says U.S. stock is sold out and will not be restocked; its U.K. campaign page lists £915. Availability is market-specific, and the purchase decision should turn on the seller, condition and completeness of the set rather than unverified resale claims.
