Frequently asked questions
What is the lug width of the Tissot PR 100 T101.210.44.031.00?
The lug width of the Tissot PR 100 T101.210.44.031.00 is 16mm. This specific measurement requires straps constructed precisely at 16mm to ensure a perfect fit to the case lugs and stable wrist wear. A strap that is too wide or too narrow would cause instability and potential internal chafing.
What is the best strap for the Tissot PR 100 T101.210.44.031.00?
The best strap depends on usage and personal preference. For everyday elegance, we recommend alligator with vegetable tanning or French calf leather. For practicality and versatility, reinforced nylon NATO straps are ideal. For water activities, vulcanised rubber or FKM straps offer resistance and complete waterproofing. All must be manufactured at 16mm width.
How do I change the strap on a Tissot PR 100 T101.210.44.031.00?
Changing the strap requires a spring bar tool: a pincer-shaped instrument that gently compresses the internal spring, allowing pin extraction. Position the watch with lugs facing upward, insert the tool into the side hole of the spring bar and extract the pin. Repeat for the other end. The new 16mm strap is inserted by reversing the procedure. If you are not experienced, consult a specialist atelier.
Is an aftermarket 16mm strap compatible with the Tissot PR 100 T101.210.44.031.00?
Yes, provided the strap is manufactured precisely at 16mm width and features compatible spring bars (standard 1.8mm diameter). Avoid generic straps from online retailers without quality guarantees: imprecise construction compromises functionality. Choose manufacturers that certify lug width and offer controlled tolerances.
How long does a leather strap last on a Tissot PR 100 T101.210.44.031.00?
A quality artisanal leather strap lasts on average 3-5 years of daily use, depending on tanning, sun exposure and body perspiration. Vegetable-tanned leather ages naturally whilst developing patina: this is not deterioration but character. Chrome-tanned leather lasts slightly longer but is less breathable. Nylon NATO straps last 5-7 years. Vulcanised rubber maintains efficiency for 10+ years if stored away from excessive heat.
