Frequently Asked Questions

Does my Rolex 116689 really need a 21mm lug width strap?

Yes, the 116689 requires exactly 21mm lug width. The measurement is non-negotiable: a narrower or wider strap won't fit correctly. Always verify your technical specs before ordering.

Which leathers do you recommend for daily wear?

Leather and calf are the most versatile and age well with use. If you need greater durability, alligator and ostrich offer superior longevity and reduced maintenance over time.

Can I customize the 21mm strap to my full length?

Yes, every strap is made-to-measure for your wrist. Provide your exact length during ordering and a custom buckle completes the strap.

What's the difference between cordovan and French calf?

Cordovan is horse leather that develops a unique patina and requires less maintenance. French calf is softer and smoother, with refined finishes. Your choice depends on your style and frequency of use.

How do I maintain a 21mm strap over time?

Clean with a damp cloth monthly and apply leather-specific cream twice a year. Avoid prolonged moisture and direct heat. A well-cared-for strap lasts years, developing character.
