Compatibility

Compatible with selected Rolex watches using the corresponding curved-end lug configuration:

• 21mm – Compatible with selected Rolex Daytona models using a matching 21mm curved-end interface
• 22mm – Compatible with selected Rolex Submariner and Yacht-Master variants using a matching 22mm curved-end interface

Important: This is a curved-end replacement strap. Compatibility depends on the specific watch reference, lug width, spring-bar position, case curvature, and lug geometry. A matching 21mm or 22mm measurement alone does not guarantee compatibility.

Please confirm your watch model, reference, lug width, and original strap/end connection before ordering. Different generations or references within the same watch collection may use different case and lug dimensions.

The final spacing between the curved strap and watch case may vary depending on the individual watch configuration. A completely flush or gapless fit is not guaranteed unless the case geometry matches the strap profile.

This is a third-party replacement watch strap compatible with selected Rolex watches. It is not manufactured, sponsored, endorsed, or authorized by Rolex. Rolex, Daytona, Submariner, and Yacht-Master are referenced solely to describe product compatibility. Watch not included.

Curved-End Fit

The curved strap ends are shaped to sit closer to compatible watch cases than a conventional straight-end strap. Because Rolex case and lug geometry can vary between collections, references, and generations, this strap should be selected according to the intended watch configuration rather than lug width alone.

How to Choose Your Size

First confirm the lug width required by your watch. Then verify that your watch reference uses a compatible curved-end and spring-bar configuration.

• 21mm: Select only for compatible models requiring the 21mm curved-end configuration
• 22mm: Select only for compatible models requiring the 22mm curved-end configuration

If you are unsure of your watch reference or lug configuration, confirm these details before ordering rather than selecting the strap based only on the measured width.
