Strap for PR 100 Quartz 38 Stainless Steel / Yellow Gold PVD / Black / Bracelet

The lug width (ansa width) of the Tissot PR 100 T049.410.22.057.01 is 20mm. This is the distance between the two bar holes where the strap is inserted. This measurement is critical for compatibility: a 20mm strap fits precisely onto the case lugs, whereas an 18mm or 22mm strap will not seat properly mechanically.

For the Tissot PR 100 T049.410.22.057.01, we recommend alligator leather with vegetable tanning in cognac or light brown tones if you seek formal elegance and wish to emphasize the gold details on the case. If you prefer daily versatility, Italian calf in black or brown is an excellent choice—robust and low-maintenance. For sports wear, heavyweight cotton NATO or vulcanised rubber maintains the model's technical character.

Changing the strap on a Tissot PR 100 is straightforward. Obtain a spring bar tool (flat-tipped strap changing tool). Insert the tip into one of the lateral slots (small grooves) beside the lug hole, then press lightly downward: the internal spring compresses and the pin withdraws from its seat. Repeat on the opposite side. Remove the old strap. Insert the new strap's lug hole onto one of the already-extracted pins, then press the second pin into position until it clicks. The operation takes less than one minute per side.

Yes, provided the lug width is exactly 20mm. Artisanal straps from Milano Straps are constructed to 20mm specifications and tested on dozens of Tissot, Seiko, Omega, and other watch brands sharing the same lug attachment. The universal bar hole (standard 1.5mm pin) guarantees complete mechanical compatibility. We recommend verifying that the strap has sufficient length for your wrist (typically 15cm to 21cm).

A quality leather strap (alligatore with vegetable tanning or Italian calf) typically lasts 4 to 7 years with daily wear, provided basic maintenance is observed: avoid prolonged immersion, clean the leather with a damp cloth every 2–3 months, apply natural wax conditioner 1–2 times yearly. Wear is primarily aesthetic (patina, light scratches) rather than mechanical. NATO and rubber straps have similar or superior longevity because they do not degrade with moisture, but do wear from fibre abrasion.
