Choose the Rolex Datejust if you want a round watch with a magnified date and a broad choice of sizes and configurations. Choose the Cartier Santos if you prefer a square design and, in the cited Medium model, the option to switch between a steel bracelet and an included leather strap. The names cover multiple models, so compare exact references and try on the size you are considering.
What separates the Datejust from the Santos?
The clearest difference is the design. The Datejust is round, with a date window magnified by Rolex’s Cyclops lens. The cited Datejust 41 reference 126334 also has a fluted bezel. Cartier describes the Santos through its square shape, rounded case angles, curved horns and exposed screws.

They are also different kinds of comparison: Datejust and Santos are collections, not single fixed specifications. Rolex lists Datejust sizes of 31, 36 and 41 mm, while the Cartier models cited here are a 35.1 mm-wide Medium and a 39.8 mm-wide Large. Case shape and diameter affect how a watch wears, so try the specific model on rather than treating the collection names as a size match. Rolex’s US Datejust collection shows its range; Cartier’s cited Santos Medium WSSA0029 page gives its dimensions and features.

How do the cited steel models compare?
This is a reference-specific comparison, not a claim that every Datejust and Santos has the same features. The Datejust details and US price below are for reference 126334; the Santos details are for Medium reference WSSA0029.
| Feature | Rolex Datejust 41, 126334 | Santos de Cartier Medium, WSSA0029 |
|---|---|---|
| Shape and appearance | Round case, fluted bezel, date magnified by a Cyclops lens | Square-shaped design, exposed screws, rounded case angles and curved horns |
| Case dimensions | 41 mm | 35.1 mm wide; 8.83 mm thick |
| Movement and stated reserve | Automatic calibre 3235; approximately 70 hours | Automatic calibre 1847 MC; power reserve not stated on the cited product page |
| Water resistance | 100 m | 10 bar, approximately 100 m |
| Bracelet or strap | Jubilee bracelet with Easylink 5 mm comfort extension | Steel bracelet with SmartLink adjustment, plus a second calfskin strap with QuickSwitch |
| Price evidence | $11,850 USD on Rolex’s US product page when accessed in 2026 | A comparable US price is not established by the cited page |
The figures come from the official product pages for the Datejust 41 126334 and Santos WSSA0029. Rolex’s listed price is specific to the US page and reference; prices and catalogues can change. The two water-resistance ratings are close, but apply only to these cited models.

Choose the Datejust if
- You want a round, traditional-looking case and a date displayed under a magnifying lens.
- You value a wider stated choice of case sizes and configurations across the collection.
- The cited 41 mm model’s Jubilee bracelet and Easylink extension suit how you want to wear it.
Choose the Santos if
- You prefer a square watch with visible screws and Cartier’s rounded case details.
- You want the cited Medium model to come with both a steel bracelet and a calfskin strap.
- You value the QuickSwitch system for changing between those included options.
These are preference-based distinctions, not evidence that one is universally better, more accurate, more durable or more prestigious. The official specifications cited here do not support those broader conclusions.

What should you check before buying?
- Pick the exact reference and size. The Datejust collection includes 31, 36 and 41 mm options, and the cited Santos Medium differs in shape and dimensions from the cited Santos Large. Confirm the reference on the listing and the seller’s paperwork.
- Try it on if possible. Compare how the case shape and width sit on your wrist, and whether the bracelet or strap feels right. A similar millimetre measurement does not make a round and square watch wear identically.
- Check current local pricing. The $11,850 figure is for the cited Datejust reference on Rolex’s US page, not a universal or enduring price. The cited Cartier page does not establish a comparable US price; check current pricing in your market.
- Verify the seller’s status. Rolex says only official Rolex jewelers are allowed to sell and maintain its watches. Confirm authorization directly through official local channels rather than assuming a marketplace seller is authorized.
