Strap for PR 100 Quartz Stainless Steel - Yelllow Gold / MOP / Bracelet

The Tissot PR 100 T101.010.22.111.00 requires an exact lug width of 12 mm. This dimension is specific to the proportions of the 25 mm case and is not interchangeable with 14, 16, or 18 mm lugs. Measurement is taken by positioning a digital calliper between the two metal spring bars protruding from the case, excluding the spring bar itself from the calculation.

The choice of strap depends on intended use and personal style. For formal and smart casual contexts, alligator leather or vegetable-tanned calf offers timeless elegance. For daily versatility, smooth calf in black, dark brown, or tobacco is the most practical solution. For sporadic or informal wear, NATO in contrasting weaves or FKM rubber maintains the sobriety of the design. All straps must have a 12 mm lug width.

Strap replacement is a straightforward operation requiring a spring bar tool (a small two-pronged instrument) or a blunt knife. Position the tool on one of the metal pins (spring bars) beneath the case, apply gentle pressure to compress the internal spring of the pin, and pull the strap outward. Repeat on the other side. Reverse the procedure to install the new 12 mm strap. We recommend performing the operation on a soft surface (mouse pad) to prevent scratches on the case.

Yes, the Tissot PR 100 T101.010.22.111.00 is fully compatible with quality aftermarket straps, provided they feature a 12 mm lug width. Artisanal straps in leather, alligator, shell cordovan, or NATO fabric of superior quality offer aesthetic versatility and durability often exceeding original straps, while maintaining full compatibility with the case's spring bars.

The lifespan of a leather strap depends on material and usage. Standard smooth calf lasts 2–4 years with moderate daily wear. Alligator leather or shell cordovan may last 5–10 years or more, thanks to the inherent density and fibre strength. Vegetable tanning ensures a patina that improves with time. Regular maintenance—gentle cleaning and annual conditioning—significantly extends operational life. Prolonged exposure to humidity or perspiration shortens durability.
