Strap for PR 100 Sport Chic Chronograph 38 Stainless Steel / MOP / Bracelet

The lug width of the Tissot PR 100 T101.917.11.116.00 is 19mm. This dimension is standard for this model and must be measured precisely using a digital calliper positioned in the cylindrical lug seats of the case. A 19mm strap fits without lateral play, ensuring correct ergonomic fit and mechanical stability during daily wear.

The best strap depends on usage and aesthetic preference. A grey-blue or dark blue alligator amplifies the controlled sporting vocation of the watch, dialoguing with the satin grain of the dial. A vegetable-tanned calf leather in dark brown offers an elegant and versatile solution. A NATO strap in canvas or satin nylon is ideal for those seeking practicality and quick changes. A satin FKM rubber constitutes the optimal choice for high-dynamics activities, providing tactile grip and extreme durability.

To change the strap, you will need a spring bar tool. Position the watch on a soft surface, insert the tool into the small slot beneath the lug, apply pressure to compress the internal spring, then extract the lug from its seat. Repeat on the other side. To install the new strap, insert the spring bars into the holes of the new strap, compress them with the tool, and snap the spring bars into the case seats until mechanical engagement clicks.

Yes, you can use any aftermarket strap with 19mm lug width, provided the construction quality respects the original piece standards. Milanostraps offers a curated selection of straps in alligator, calf, NATO, and rubber, all designed for 19mm lug width and compatible with the PR 100. Artisanal quality guarantees precise fit without lateral play or visible misalignment.

Leather strap longevity depends on frequency of use and maintenance. A quality artisanal alligator or calf strap, worn daily under normal conditions (absence of water, excessive perspiration, mechanical shocks), has a useful life of 3-5 years. The patina that naturally develops increases the aesthetic character of the piece. To extend durability, avoid prolonged humidity exposure, occasionally apply leather conditioner, and consider rotating multiple straps if usage is intensive.
