Frequently asked questions

What is the lug width of the Tissot PR 100 T049.407.22.031.00?

The lug width of the Tissot PR 100 T049.407.22.031.00 is 20 millimetres. This standardised dimension ensures compatibility with a broad range of aftermarket leather, fabric, and rubber straps. To verify the measurement with precision, use a digital calliper to measure the internal spacing between the upper and lower lugs.

Which strap is recommended for the Tissot PR 100 T049.407.22.031.00?

The ideal strap depends on intended use. For professional-elegant contexts, vegetable-tanned leather in brown or black is recommended; for sportive-daily environments, NATO fabric or FKM rubber. Alligator represents the luxury option, whilst vulcanised silicone guarantees extreme performance in marine or humid settings. Milano Straps curates selections for each user profile.

How do I change the strap on a Tissot PR 100 T049.407.22.031.00?

The PR 100 T049.407.22.031.00 features straight lugs. For removal: position the watch on a protective stand, use a spring bar tool (bifurcated-tip implement) to compress the internal spring, extract the old strap. Installation of the new strap follows the reverse procedure: insert the bar, allow the spring to re-engage in the lug holes. The operation requires 3–5 minutes and only a spring bar tool.

Is a 20mm aftermarket strap compatible with the Tissot PR 100?

Yes, any strap with a 20mm lug width is compatible with the Tissot PR 100 T049.407.22.031.00. Artisanal straps from Milano Straps, crafted with straight lugs, fit perfectly on the steel case. It is advisable to verify strap thickness (not exceeding 4–5mm in leather) for aesthetic balance with the case's refined proportions.

How long does a leather strap last on a Tissot PR 100?

Durability depends on leather quality and usage intensity. A quality vegetable-tanned leather strap (such as Milano Straps offerings) resists 3–5 years of daily wear, developing a fascinating natural patina. Exposure to humidity, perspiration, and UV rays accelerates ageing. Longevity extends to 5–7 years with preventative care: periodic cleaning, avoiding prolonged immersion, storing in dry environments. FKM rubber guarantees 7–10 years without visible degradation.
