Custom strap for Ulysse Nardin Marine Chronometer 263-66

Handmade from black alligator leather with ergonomic design

This bespoke Ulysse Nardin Marine Chronometer strap was created for a client who wanted a refined, handmade replacement for the original strap — one that would respect the strong character of the 263-66 reference while enhancing its comfort and elegance.

The strap is handcrafted from carefully selected black alligator leather, featuring a matte finish and even grain. Its design reflects a balance of strength and sophistication, perfectly complementing the bold and highly recognizable case of the Marine Chronometer.

Unlike factory straps that are made flat and often uncomfortable at first, this strap is built with an ergonomic, anatomically curved shape. It follows the natural contour of the wrist, providing immediate comfort without the need for a break-in period — one of the key differences between bespoke and mass-produced watch straps.

For stitching, I used traditional saddle stitching, done entirely by hand using strong waxed linen thread. This method ensures exceptional durability and adds a subtle, handcrafted texture to the overall look.

The interior is lined with a hypoallergenic, moisture-resistant leather in a neutral flesh tone. This lining was chosen not only for comfort, but also for skin compatibility and daily practicality.

Every aspect of this strap — from material selection to construction — is aimed at elevating the experience of wearing the Ulysse Nardin Marine Chronometer. It’s not just a strap, but a tailored addition to a prestigious timepiece.

Whether worn for business or travel, this Ulysse Nardin Marine Chronometer strap enhances the watch’s identity while offering superior comfort and refined execution.
