Strap for Ode à la Semaine / Friday

The lug width of the WCF20TJFRWG01AA is 20 mm. This measurement represents the distance between the two spring bars (lugs) of the case and is essential to ensure perfect compatibility with any aftermarket strap. Measurement should be taken precisely between the lugs, excluding any spacing washers.

For the WCF20TJFRWG01AA we recommend alligator or vegetable-tanned calf for a formal aesthetic that enhances the white gold case. Alligator offers fine, regular texture, perfect for elegant contexts; calf will develop patina over time, creating visible history. For daily use and versatility, NATO or FKM rubber guarantee frequent replacement practicality without structural compromise.

Strap replacement is done by removing the spring bars (small pins connecting the case to the strap lugs) using a dedicated spring bar tool. Insert the tool on one side of the lug, apply gentle pressure to release the attachment, then remove the old strap. Repeat on the other side. Insert the new strap by clicking the spring bars into their housings until they lock in place. Verify that the strap is properly seated on both sides.

Yes, provided it respects the 20 mm lug width. Quality aftermarket straps (leather, NATO, rubber) are fully compatible with the WCF20TJFRWG01AA. We recommend choosing robust materials that properly complement the weight and value of white gold: vegetable-tanned calf, alligator, or technical rubber for a sporty alternative. Avoid thin straps that may appear disproportionate to the substantial case.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years with moderate daily use, up to 7-10 years with proper care and seasonal rotation. Longevity depends on: frequency of use, exposure to moisture, sweat and temperature variations, and periodic maintenance (gentle cleaning, occasional conditioning). A NATO strap lasts 2-3 years before losing elasticity. FKM rubber has a similar lifespan to NATO (2-4 years) depending on UV exposure and mechanical wear.
