Strap for PR 100 Sport Chic Chronograph 38 Stainless Steel / Rose Gold PVD / MOP / Bracelet

The Tissot PR 100 T101.917.22.151.00 features a lug width of 19mm. This measurement represents the internal distance between the two upper lugs. Compatible straps must respect this dimension with minimal manufacturing tolerance (±0.1mm). To measure correctly, use a digital calliper positioned on the inside of the lugs, not on their external circumference.

The Tissot PR 100 pairs ideally with straps in alligator leather (black or dark brown), vegetable-tanned calf, or technical fabric NATO. Choice depends on usage context: alligator for formal settings, vegetable-tanned calf for those who appreciate natural patina development, NATO for versatility and sport practicality. The soberness of the case requires straps without excessive texture that distracts from the watch's geometry.

Strap replacement is performed by removing the lug pins (typically stainless steel, 1.2-1.5mm diameter). Use a dedicated tool (spring bar tool) or precision instrument to compress the internal spring and extract the pin from its seat. Insert the new strap by aligning the pins with the lug holes, pushing until the locking click is felt. Avoid hammers or unsuitable tools that damage lug finishes.

All straps manufactured with 19mm lug width are compatible with the PR 100. Compatibility depends on respecting this dimension. Milanostraps offers a dedicated selection of 19mm straps in artisanal leather, NATO fabric, and synthetic rubber. Construction quality and finishing are essential to ensure fluid pairing without play or rigidity.

A quality leather strap (alligator or vegetable-tanned calf) maintains structural functionality for 3-5 years of moderate use, with rotation every 2-3 days. Durability depends on humidity exposure, sunlight, skin acids, and wearing frequency. Alligator straps age more slowly than calf. Fabric NATO straps resist longer (5-7 years), while synthetic rubber degrades faster after 4-6 years in warm climates. Periodic maintenance (cleaning, conditioning) significantly extends useful life.
