Strap for PR 100 Quartz 40 Stainless Steel / Silver

The lug width of the Tissot PR 100 reference T150.410.16.031.00 is 20mm. This dimension represents the space between the two lugs of the case where the strap is inserted via the spring bars. It is essential to verify this measurement before purchasing an aftermarket strap to ensure perfect compatibility.

The best strap depends on intended use and dial colour. For elegance, we recommend vegetable-tanned alligator or shell cordovan. For everyday versatility, vegetable-tanned calf leather in cognac or brown is ideal. For sports environments, an organic cotton NATO maintains the minimalist profile. In any case, a deployante clasp ensures greater security and longevity.

Strap replacement requires a spring bar tool. Position the watch on a soft surface, insert the tool into the lateral hole of the lug, push the spring bar downward to release it, remove the old strap. Align the new strap with the lugs and reinsert the bar until it clicks into place. If you are not confident, we recommend consulting a qualified watchmaker to avoid damage.

Yes, provided the lug width is exactly 20mm. Artisanal leather, NATO, or rubber straps of high quality are fully compatible and often offer superior aesthetics compared to the original strap. Ensure that the spring bar diameter matches (typically 1.8mm for this model) and that the strap does not touch the crystal or case.

A high-quality leather strap with vegetable tanning and artisanal finishing typically lasts 3–5 years with daily use, provided regular maintenance: avoid stagnant water, dry after use, and occasionally apply a natural wax treatment. The patina that develops over time is normal and desirable. Rubber and NATO straps offer similar longevity but handle moisture more effectively.
