PRC 100 T151.422.36.051.00— lug 20mm

The lug width of the Tissot PRC 100 T151.422.36.051.00 is 20 mm. This measurement represents the distance between the two anchor points of the spring bar on the case. Precision is critical when purchasing an aftermarket strap, as even a 1 mm variance will compromise correct fitment.

For the T151.422.36.051.00, we recommend three primary options: a satin-finished alligator leather in grey or blue tones to emphasise the technical character of the stainless steel case; vegetable-tanned calf leather in cognac or dark brown to introduce warmth without compromising austerity; a grey or black polyamide NATO for a sportive and versatile approach. Your choice depends on context of use and personal preferences.

The Tissot PRC 100 uses a spring bar attachment system. Proceed as follows: position the watch face-down on a soft surface; locate the small slot beneath the lug; insert an extraction pin (or dedicated tool) into the slot to compress the spring; remove the spring bar from the old strap; insert the spring bar into the new strap, ensuring the attachment is secure before closing.

Yes, any strap with a 20 mm lug width is compatible with the T151.422.36.051.00. Always verify that the strap has been precisely measured by the manufacturer and that the attachment system (spring bar) is intact. Artisanal straps crafted from natural leather or technical materials ensure durability and certified compatibility.

The lifespan of a leather strap depends on material quality and intensity of use. A premium leather strap with vegetable tanning lasts an average of 3–5 years with daily wear. Factors such as humidity, solar exposure, and mechanical stress accelerate wear. The natural patina that develops over time is a positive aesthetic sign of ageing, not functional deterioration.
