Strap for PR 100 Quartz 39 Stainless Steel / Grey / Strap

The lug width (measured distance between the lugs) of the Tissot PR 100 T101.410.16.441.00 is 20 millimetres. This dimension represents the gap between the two parallel pins protruding from the case flanks. Measurement should be performed with a digital calliper positioned perpendicular to the pins. Only straps with 20 mm lugs are compatible with this model.

Selection depends on intended use. For formal contexts, we recommend alligator in medium brown or grey tones, or vegetable-tanned calf leather which develops natural patina over time. For casual-sports wear, ballistic nylon NATO straps (navy, grey, black) maintain aesthetic coherence with the watch's discrete character. For warm climates, fluorocarbon rubber delivers robustness without compromise.

The strap is secured by spring bars inserted through the case lugs. To replace: 1) rest the watch on a soft surface; 2) use a dedicated spring bar tool to gently press the bars toward the case centre; 3) extract the strap downward; 4) align the new strap lugs with the pins; 5) ensure spring bars are fully seated. This procedure is straightforward but requires care to prevent case scratching.

Yes, all straps featuring 20 mm lug width are compatible with the PR 100 T101.410.16.441.00. Numerous artisanal options are commercially available: full-grain leather, alligator, vegetable-tanned calf, NATO, and rubber. Compatibility is assured by standard lug dimensions; always verify that the strap lug width is precisely 20 mm before purchase.

Leather strap durability depends on material quality and usage intensity. An artisanal full-grain or alligator strap guarantees 3–5 years of daily wear if properly maintained: avoid prolonged moisture exposure, protect from excessive perspiration (particularly the interior surface), and periodically apply natural balms. Vegetable-tanned leather develops increasingly attractive patina over time. Premium vegetable-tanned calf straps may remain serviceable beyond five years whilst improving aesthetically.
