Strap for PR 100 Sport Gent Chronograph Stainless Steel / Blue / Bracelet

The lug width of the Tissot PR 100 T101.617.11.041.00 is 22mm. This measurement represents the distance between the two case lugs and is essential for selecting compatible straps. Measurement should be taken perpendicular to the case plane using a digital or mechanical calliper between the inner edges of the spring bar holes.

For the PR 100, we recommend a Tuscan leather strap with vegetable tanning, which balances elegance and daily durability. If you seek moisture resistance and quick changes, a NATO strap in grey or navy blue nylon is ideal. For formal contexts, an alligator strap in black or cordovan in dark brown enhance the watch's character whilst maintaining its aesthetic balance.

Strap change is accomplished by removing the spring bars that connect the strap to the case lugs. Use a spring bar tool (bifurcated rod) to gently compress the bar towards the case, creating sufficient space to extract it laterally. Insert the new strap and reinsert the bar until you feel the locking click. Verify that the spring bar sits correctly without twists.

All straps with 22mm lug width are compatible with the T101.617.11.041.00. This includes vegetable-tanned leather, shell cordovan, alligator, calf, NATO, canvas and FKM rubber. Ensure the internal opening of the spring bar hole is at least 24-25mm to allow passage without excessive compression that could damage either the strap or the lug.

Lifespan depends on use, tanning method and construction quality. A quality vegetable-tanned leather strap, worn daily, maintains structural and aesthetic integrity for 3-5 years. Cordovan can exceed 7-10 years. A nylon NATO strap lasts at least 5-8 years before visible wear. Maintenance (periodic cleaning, drying after perspiration) significantly extends the longevity of any material.
