Strap for PRC 100 Solar Quartz 39 PVD / Black / Bracelet

The lug width of the Tissot PRC 100 T151.422.33.051.00 is 20mm, measured between the internal suspension pins of the watch case. This is a rare specification in contemporary timepieces, requiring bespoke strap craftsmanship to ensure perfect compatibility and eliminate mechanical play.

Three primary options complement the PRC 100: (1) naturally tanned alligator leather, delivering tactical elegance and rich patina development over years; (2) vegetable-tanned calfskin, robust and versatile for daily wear, visibly recording the passage of time; (3) cotton-nylon NATO strap, preserving the instrument character and performing reliably in humid environments. Selection depends on use context and personal aesthetic preference.

To replace the strap, obtain a spring bar removal tool. Position the watch on a stable surface, locate the spring bars (small pins on each lug), use the tool to gently depress the retaining mechanism, and slide out the old strap. Install the new 20mm strap by aligning its pins with the lugs and pressing until the spring bars lock. If inexperienced, consult a professional watchmaker to prevent damage to the lugs.

Yes, provided the strap has a precisely 20mm lug width. However, we strongly recommend artisanal quality straps: they guarantee precise construction tolerances, elimination of mechanical play, and superior longevity compared to industrial production. A well-crafted leather or rubber strap also delivers superior grip and develops an authentic patina that improves with use.

Strap lifespan depends on tanning method and daily usage intensity. A well-constructed vegetable-tanned strap typically lasts 4-6 years of regular wear; alligator may reach 7-10 years. Maintenance significantly extends service life: avoid prolonged sun exposure, keep leather dry, and apply protective balms every 6-12 months. Patina development and micro-creasing are authenticity markers, not deterioration signs.
