Strap for PR 100 Sport Chic Chronograph 38 Rose Gold PVD / MOP / Bracelet

The lug width of the Tissot PR 100 T101.917.33.116.00 is 19mm. This measurement refers to the distance between the two holes that accommodate the strap lugs on the watch case. To verify accurately, use a digital calliper positioned on the internal shoulder of the case, between the lug holes.

The best strap depends on your intended use. For formal elegance, vegetable-tanned alligator in cognac tone offers versatility and develops a natural patina over time. For daily sports use, a nylon ballistic NATO strap provides durability and easy maintenance. For humid environments, certified FKM natural rubber ensures superior grip and longevity.

Strap replacement requires a spring bar tool. Position the flat end of the tool against the spring-loaded pin, pressing gently inward toward the case to release the old strap. Insert the lugs of the new strap into the case holes and compress the pin again until it clicks into position. Verify the strap is securely anchored before wearing the watch.

Any strap with exactly 19mm lug width is compatible. We recommend artisanal straps in alligator, calf leather, shell cordovan, or NATO. Ensure the strap specifications clearly state 19mm width, as this atypical measurement is not standard in mass-market budget straps.

A vegetable-tanned alligator strap lasts 5-7 years with regular rotation (worn 3-4 times per week). Calf leather lasts 3-5 years due to its more delicate texture. Longevity depends on exposure to moisture, perspiration, and maintenance. Applying protective balms every 6 months significantly extends useful life.
