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

The Tissot PR 100 ref. T101.417.11.051.00 features a 20mm lug width. This measurement is the standard construction specification for the PR 100 line and is determined by the internal width of the lugs integrated into the case. It is crucial to verify this measurement before ordering an aftermarket strap to prevent incompatibility. Correct measurement is performed by inserting a digital calliper perpendicular to the internal walls of the lugs, excluding any play due to natural wear.

The ideal strap depends on usage and aesthetic preference. For a formal approach, we recommend alligator leather in natural tones or vegetable-tanned calf that develops patina over time. For a sporty profile, NATO straps in resistant cotton or vulcanised rubber reinforce the chronograph character. Shell cordovan, if available in 20mm width, offers superior density and lasting lustre. Reversible options (leather/rubber) provide versatility without multiple purchases.

Strap replacement is achieved by extracting the spring bars that connect the lug to the case. Use a dedicated spring bar removal tool, inserting the lever under the bar and gently pushing upward to release the internal spring. Once the lugs are freed, the previous strap slides out easily. The new strap (20mm) must be perfectly aligned with the lugs before reinserting the bars. Work on a soft surface to prevent case scratching.

Yes, numerous artisanal 20mm straps are specifically engineered for the Tissot PR 100. milanostraps.it offers a comprehensive collection of leather straps (alligator, calf, shell cordovan), technical textiles, vulcanised rubber and NATO straps. Each strap is available with standard finishes or customisations (colour, stitching, buckle). Compatibility is guaranteed by the 20mm lug width and the absence of unnecessary adapters.

Leather strap longevity depends on tanning quality, intensity of use and maintenance. A high-quality alligator or calf strap with vegetable tanning lasts an average of 4–7 years with daily wear if subjected to regular maintenance (cleaning, occasional conditioning). Vulcanised rubber offers superior longevity (8–10 years) due to the absence of moisture absorption. Factors accelerating wear include prolonged direct sunlight exposure, frequent salt water contact and extreme temperatures. Rotating between multiple straps increases the overall durability of each.
