Strap for PR 100 Chronograph Quartz 41 PVD / Grey / Milanese

The lug width of the Tissot PR 100 T101.417.23.061.00 is exactly 20 mm. This measurement represents the distance between the two vertical pins where the strap attaches to the case. It is essential to verify this with a digital calliper before purchasing an aftermarket strap to ensure perfect compatibility and no gaps between lug and strap keeper.

For the PR 100 T101.417.23.061.00, the most coherent straps are: alligator (natural geometric grain that complements steel and PVD), vegetable-tanned calf leather (authentic patina and dignified ageing), ballistic nylon NATO (complete sportive transformation), FKM rubber (urban-outdoor versatility). Your choice depends on intended use and desired aesthetic statement.

Remove the watch from your wrist. Use a spring bar tool to gently lift the internal retention pin on each side. Once the springs are released, pull the old strap outward to remove it. Align the new strap holes with the pins and press the tool to recompress the springs until they click into place. Verify that the strap is securely fastened before wearing the watch.

All straps with a 20 mm lug width are compatible with the T101.417.23.061.00. Ensure the strap is at least 20 mm wide in the attachment sections. Avoid models with smaller lug widths (16-18 mm) that would create empty spaces. Also verify that the strap keeper is not so rigid that it could damage the case's satin finish.

A quality leather strap (alligator, vegetable-tanned calf) lasts 3-5 years with moderate daily use, up to 7-8 years with rotation with other straps. Durability factors include: humidity (sweat shortens lifespan), direct sun exposure (fades and hardens fibres), frequency of use, and maintenance with protective treatments. FKM rubber lasts longer (8-10 years) but requires regular cleaning to maintain elasticity.
