FAQ

What is the lug width of the Tissot T-Touch Expert Solar T091.420.47.051.01?

The lug width is 22mm. This specific measurement ensures correct proportion between the 45mm case and the lugs. Measure the internal distance between the two lateral lugs of the case, wall to wall, to verify this dimension. Only straps manufactured for the 22mm lug width will be compatible with this model.

Which strap do you recommend for the T091.420.47.051.01?

For the Tissot T-Touch Expert Solar, we recommend high-quality vegetable-tanned leather, such as natural-dyed alligator or shell cordovan, in dark tones such as fawn brown or black. These materials respect the technical character of the instrument whilst maintaining elegance. For more severe environments, a ballistic nylon NATO strap or hi-tech rubber bracelet offers practicality without functional compromise.

How do you change the strap on the T091.420.47.051.01?

Use a soft plastic or wooden strap changing tool, never metal tools. Position the watch with the case facing downwards, lugs parallel to the work surface. Push the spring bar towards the inside with firm, gradual pressure. The titanium case is robust but merits careful handling: if inexperienced, consult a certified watchmaker.

Which aftermarket straps are compatible with the Tissot T-Touch T091.420.47.051.01?

Any strap designed for the 22mm lug width will be compatible with this model. Milano Straps offers a selection of straps in Tuscan leather vegetable-tanned, alligator leather, shell cordovan, ballistic nylon NATO bracers and hi-tech rubber straps, all available in 22mm lug width and ready for shipping.

How long does a leather strap last on the T091.420.47.051.01?

A high-quality leather strap (alligator, shell cordovan, vegetable-tanned calf) typically lasts 3–5 years in daily use, with variability due to climate, sun exposure and maintenance. Vegetable-tanned leather ages visibly, accumulating patina and developing aesthetic character over time. To extend its lifespan, protect the strap from prolonged moisture, apply specific balms every 6–12 months and alternate with replacement straps during periods of heavy perspiration.
