Strap for PRC 100 Solar Quartz 39 Stainless Steel / Silver

The Tissot PRC 100 T151.422.16.031.00 features a lug width of precisely 20 millimetres. This dimension represents the distance between the two attachment points of the strap to the case and is the fundamental parameter for identifying compatible straps. To verify the measurement, use a digital calliper, positioning it between the lateral metal pins. Only straps with a 20mm lug width will fit correctly without modifications to the case.

The choice of strap depends on intended use and aesthetic preference. For everyday excellence, we recommend an alligator strap with vegetable tanning, which imparts a bespoke dimension to the rational dial. For versatility, a smooth or fine-grained calf offers superior comfort and colour adaptability. For dynamic use and humid environments, a NATO strap in Cordura fabric or vulcanised rubber ensures uncompromised functionality, emphasising the sporting DNA of the PRC 100.

Changing the strap on the PRC 100 T151.422.16.031.00 is a straightforward operation requiring a spring bar tool. Position the watch with sides parallel to the ground. Insert the tool tip into the small aperture beneath the lateral metal pin and press gently inward to release spring tension. Extract the old pin. Repeat for the other side. Insert the new strap pins in the same manner. Ensure pins are completely seated and symmetrical before wearing the watch.

Yes, any strap with a 20mm lug width is fully compatible with the T151.422.16.031.00. Quality aftermarket straps offer the same fit level as genuine Tissot parts, eliminating dependence on proprietary component availability. Always verify that the lug width is precisely 20 millimetres before purchase. Milanostraps offers a selection of 20mm straps in fine leather, NATO fabrics and rubber, with rapid delivery and online customisation options.

The lifespan of a leather strap depends on tanning quality, usage frequency and environmental conditions. An alligator strap with vegetable tanning, with appropriate maintenance (periodic cleaning, protection from excessive moisture), can last 3–5 years of intensive daily use. Superior calf offers comparable durability. Constant solar exposure, typical of the PRC 100 with solar charging, does not compromise leather if properly shielded from excessive direct heat. The patina that develops over time is natural and desirable, signalling authenticity. Replacing the strap when it shows structural fatigue maintains the watch's overall appearance at peak level.
