Strap for PR 100 Quartz 38 Titanium / Blue / Bracelet

The lug width of the Tissot PR 100 T049.410.44.041.00 is precisely 20 millimetres. This measurement refers to the internal distance between the spring bar pins that attach to the watch case. It is crucial not to confuse this with the total width of the case. A 20mm strap is the only correct fit; alternative dimensions result in physical incompatibility.

For the Tissot PR 100 in titanium, an alligator strap with vegetable tanning offers the strongest aesthetic contrast, enhancing the technical nature of the case. Alternatively, fine-grained calf leather in dark brown or black provides understated elegance and durability. NATO straps in technical fabric ensure daily versatility, whilst FKM rubber represents the choice for water resistance and minimal maintenance requirements.

Strap replacement requires a precision tool—either a spring bar tool or pin remover. Position the watch on a stable surface and locate the metal pin securing the strap to the case (typically at 9 and 15 o'clock positions). Apply gentle pressure with the tool to compress the internal spring mechanism, then extract the pin outward. Reverse the process to install the new strap, ensuring the pin locks correctly on both sides. The procedure is straightforward when executed with attention to detail.

Yes, any 20-millimetre strap is mechanically compatible. However, aesthetic compatibility represents a separate consideration. The Tissot PR 100 in titanium demands materials that dialogue with its modern nature: premium leathers, technical fabrics, or quality elastomers. Economy straps or incongruous designs diminish the watch's construction quality. Milano Straps curates 20mm artisanal straps specifically for this category.

Longevity depends upon leather quality, usage patterns, and maintenance discipline. An alligator strap with certified vegetable tanning can exceed 5–7 years of daily wear whilst developing an attractive patina. Mid-range calf leather typically lasts 3–5 years before exhibiting creasing at the lugs or minor fractures. Sun exposure, perspiration, and moisture accelerate degradation. Basic maintenance—periodic cleaning, drying after water contact, occasional conditioning—substantially extends strap lifespan.
