Strap for PR 100 Chronograph Quartz 41 Stainless Steel / Black / Strap

The Tissot PR 100 reference T101.417.16.051.00 features a lug width of 20 mm. This measurement represents the internal distance between the case attachment lugs, measured from edge to edge. You can verify this dimension using a digital calliper positioned between the connection holes. A 20 mm lug width offers an interesting selection of aftermarket straps without confining you to exceptionally rare solutions nor overwhelming you with excessive alternatives.

The choice of strap depends on intended use and aesthetic preferences. For an elegant and sporty combination, an alligator strap with fine grain in dark brown or black tones enhances the geometry of the stainless steel case. For a more casual and versatile aesthetic, the NATO strap in cotton-polyester remains the most practical solution. For those wishing to fully exploit the chronograph functions, vulcanised rubber offers comfort and practicality without compromise. Calf leather with vegetable tanning represents the fulfilment of authenticity, developing a natural patina that dialogues with the case's natural ageing.

Strap replacement requires a specific tool: a spring bar removal tool. Position yourself in a well-lit environment and, using the tool, gently push the connecting bars inward towards the case, sliding the old strap out from the lugs. Insert the new strap by aligning the end links with the holes and, using the tool again, secure the bars in position. Ensure both bars are firmly fixed before wearing the watch. If you are uncertain about the procedure, consulting a qualified watchmaker is the most prudent choice.

All straps with a 20 mm lug width are compatible with the Tissot PR 100 T101.417.16.051.00. This measurement permits the use of leather straps (alligator, calf, vegetable tanned leather), NATO fabric straps, vulcanised rubber straps and canvas straps. It is essential to verify that the chosen strap is specifically designed for a 20 mm width to ensure correct fitting to the case's attachment lugs.

The lifespan of a leather strap depends on use, environmental conditions and material quality. A quality alligator or calf strap, subject to ordinary use (approximately 8-10 hours daily), maintains structural integrity and aesthetic appearance for 3-5 years. Natural leather is a living material that evolves over time: it develops a patina that narrates the history of use. Prolonged exposure to humidity, direct sunlight and perspiration accelerates ageing. Periodic maintenance (gentle cleaning, conditioning with specialist products) significantly extends lifespan. Vulcanised rubber straps, by contrast, have an average lifespan of 2-3 years before losing elasticity.
