Strap for PR 100 39 Dual Time Stainless Steel / Yellow Gold / Silver / Strap

The lug width of the Tissot PR 100 T101.452.26.031.00 is 20 mm. This measurement represents the vertical distance between the case attachment pins. It is the contemporary standard for 41 mm diameter watches with straight, parallel lugs rather than angled attachments.

For the Tissot PR 100 T101.452.26.031.00, we recommend a vegetable-tanned calf leather strap in dark brown (mahogany or chestnut). This choice respects the minimalist aesthetic of the watch and the lateral flexibility of leather allows ergonomic adaptation to the case's straight lugs. Alternatively, a woven NATO strap offers sports versatility while maintaining balanced proportions.

The Tissot PR 100 T101.452.26.031.00 features standard straight lugs with spring bar pins. To change the strap: 1) obtain a spring bar tool; 2) position the tool under the lateral pin; 3) gently lift to slide the pin out of its housing; 4) remove the old strap; 5) insert the new strap by aligning the holes; 6) slide the pin until you hear a click of security. Repeat for the second attachment.

Yes, any strap with a 20 mm lug width is compatible with the Tissot PR 100 T101.452.26.031.00. However, the straight lugs require straps with parallel lugs (not curved). We recommend selecting artisanal straps in vegetable-tanned leather, woven NATO, or vulcanised rubber that guarantee constructive compatibility and aesthetic suitability to the case proportions.

The durability of a leather strap varies according to material quality and wear patterns. A vegetable-tanned calf leather strap worn daily maintains structural integrity for 3–4 years. Factors influencing longevity include ambient humidity, washing frequency, solar exposure, and sweat pH. Superior quality leather (shell cordovan) can reach 5–6 years. Maintenance with natural balms significantly extends service life.
