Frequently asked questions

What is the exact lug width of the Tissot Gentleman T127.407.16.051.00?

The lug width of the Tissot Gentleman T127.407.16.051.00 is 21mm. This measurement is taken between the two attachment points of the case (lugs) and represents the space where the strap must fit precisely. You can verify it using a digital calliper, measuring the internal distance between the two spring bars on the case.

Which strap material is best suited to the Gentleman T127.407.16.051.00?

For the Tissot Gentleman T127.407.16.051.00 we recommend a full-grain alligator strap with vegetable tanning for formal occasions, or premium calf leather with medium grain texture for daily wear. Both materials respect the sober elegance of the watch. For a sportier approach, a cotton NATO maintains aesthetic dignity with greater versatility.

How do you change the strap on a Tissot Gentleman?

The Tissot Gentleman uses a standard lug system: you need a spring bar remover (or a small flathead screwdriver) to push the spring pin that protrudes from each lug. Once the pin is released, the old strap slides out easily. Align the new strap with the lugs, then reinsert the spring pin until it clicks into place. Ensure the strap is secure before wearing the watch.

Can I use an aftermarket 21mm strap on this Gentleman?

Yes, absolutely. The Tissot Gentleman T127.407.16.051.00 accepts any strap made for 21mm lug width, regardless of manufacturer. Compatible straps include alligator, shell cordovan, calf, NATO, rubber and specialised fabrics. What matters is verifying that the lug width is exactly 21mm and that strap thickness is proportionate to the case.

How long does a leather strap last on the Tissot Gentleman?

The lifespan of a leather strap depends on the tanning method and daily use. A vegetable-tanned alligator strap typically lasts 3–5 years under normal conditions; calf leather resists 2–4 years. Exposure to water, direct sunlight and perspiration accelerates wear. Proper maintenance—drying after water contact, occasional application of leather balm—extends the strap's useful life.
