Strap for PR 100 Sport Chic 36 Stainless Steel / Rose Gold PVD / Grey / Bracelet

The lug width of the Tissot PR 100 T101.910.22.061.00 is 18 millimetres. This measurement is specific to this model and was chosen to maintain harmonious proportions relative to the 36mm case diameter. Measuring the lugs is performed by positioning a digital calliper from the inside of one lug to the other, completely excluding the case. An 18mm lug width accommodates straps in structured leather, calf skin, alligator and NATO with perfect balance.

The best strap depends on intended use and desired aesthetic. For formal contexts we recommend alligator leather in black or cognac, which enhances the rose gold case. For daily wear, artisanally tanned calf skin with developing patina offers softness and aesthetic evolution over time. For casual style, a navy NATO maintains formal elegance while allowing frequent changes. FKM rubber in black is ideal for those seeking material contrast between strap and metal case, providing grip even in humid conditions.

Changing the strap on the Tissot PR 100 T101.910.22.061.00 takes only minutes and requires minimal tools. Position the watch on a soft surface (cloth or foam pad) and use a spring bar tool to remove the elastic pin connecting the strap to the lugs. Extract the old strap by carefully pushing the pin inward. Insert the new strap in the same position and snap the pin into place until you hear a click of engagement. Verify that the strap is stable on both sides before wearing the watch.

Yes, 18mm aftermarket straps are completely compatible with the Tissot PR 100 T101.910.22.061.00. The model's lugs use standard spring bars, identical to those on many other 36mm watches. Artisanal straps in Italian leather, calf skin with vegetable tanning, alligator and NATO in nylon or Cordura fabric are available online and offer superior quality to the original Tissot strap. Before purchase, always verify that the strap is specific for 18mm lug width.

A quality leather strap for the Tissot PR 100 T101.910.22.061.00 lasts on average 2-4 years with daily wear, depending on the tanning quality and environmental conditions. Calf skin tanned with vegetable tanning, whilst more delicate initially, improves over time by developing patina and softness. Alligator, more resistant to flexing, extends lifespan to 4-6 years. Wear accelerates in humid environments or if the watch is systematically worn during activities that wet the wrist. Proper maintenance—regular cleaning with a damp cloth, rapid drying, annual conditioning—significantly extends strap life.
