Strap for PRS 200 Quartz Chronograph Blue

The lug width of the Tissot PRS 200 T17.1.486.44 is 19.00 mm. This measurement is determined by the geometric proportions of the 39.80 mm case and its soldered lugs. A compatible strap must have internal lugs of exactly 19 mm; even variations of 0.5 mm cause mounting instability.

For the Tissot PRS 200 T17.1.486.44, we recommend four options: vegetable-tanned alligator for historical aesthetic continuity; chromium-plated box calf for mechanical resistance and smooth surface; cordura NATO for operational versatility and security; FKM (Viton) rubber for tactical applications and chemical resistance. Selection depends on the declared use of the watch.

Position a digital calliper between the two lugs, perpendicular to the case plane, without crushing the lugs. The measured value must correspond exactly to 19.00 mm for the PRS 200. Avoid measuring on the external surface of the lugs, which would give a falsified value.

Yes, provided it has been constructed to ISO 1795 standard specifications and has certified internal lugs of 19 mm. High-end artisanal leather straps offer superior aesthetic balance compared to original Tissot straps, provided they are sewn and assembled by specialised ateliers.

An alligator or vegetable-tanned calf strap of quality lasts on average 4–6 years with daily wear, provided constant maintenance (gentle cleaning, conditioning with neutral wax, protection from direct heat sources). Wear accelerates in humid or salt-marsh environments. NATO and rubber straps have superior durability, 8–10 years, as they are not subject to biological degradation of collagen.
