The PR 100 T049.310.44.041.00 (aka: T0493104404100), seen from the bench

The Tissot PR 100 T049.310.44.041.00 is a contemporary sports watch from the Vallée de Joux tradition, featuring a 27mm titanium case with brushed finishing and blue dial. Powered by the ETA F03.111 manual-wound movement with hours, minutes, seconds and date window, it delivers 100 meters water resistance. The 20mm lug width is integrated into the case structure. Titanium construction provides hypoallergenic properties and reduced weight while maintaining structural rigidity.

Frequently asked questions

What is the exact lug width of the Tissot PR 100 T049.310.44.041.00?

The Tissot PR 100 T049.310.44.041.00 features a precisely engineered 20mm lug width. The lugs are forged integrally into the titanium case and are not removable, meaning any replacement strap must comply rigorously with this specification to ensure mechanical stability and correct fit.

What is the best strap choice for the Tissot PR 100 T049.310.44.041.00?

For this brushed titanium case, we recommend either vegetable-tanned alligator leather in dark tones (black or tobacco brown) or full-grain calf leather. Alligator accentuates the contrast between titanium's metallicity and organic material, whilst calf delivers visual warmth that tempers the perceived coldness of the case. For sportive wear, a cotton-polyester NATO or fluorosilicone rubber strap delivers practicality and durability.

How do I change the strap on the Tissot PR 100 T049.310.44.041.00?

Since the T049.310.44.041.00 features integrated, non-removable lugs, strap replacement requires a precision spring bar tool inserted carefully into the micro-holes positioned above and below each lug. Removal must employ controlled motion to avoid scratching the titanium case. Professional watchmakers or Casati Milano atelier services are recommended for this operation.

Can I use an aftermarket strap compatible with my Tissot PR 100?

Absolutely, provided the strap measures precisely 20mm lug width. Numerous specialised manufacturers, including Milano Straps, produce bespoke leather, rubber and fabric straps compatible with this specification. A quality aftermarket strap can substantially enhance aesthetics and comfort compared to the original equipment, particularly in materials such as alligator or vegetable-tanned calf.

What is the lifespan of a leather strap on the Tissot PR 100?

A quality vegetable-tanned leather strap, worn daily, typically provides 3-5 years of service before replacement becomes necessary. Longevity depends on environmental humidity, frequency of wear and sun exposure. Rubber straps extend to 5-7 years, whilst fabric NATO straps frequently surpass 7 years of reliable service. Regular maintenance – gentle cleaning and leather conditioning – significantly extends functional lifespan.
