Frequently asked questions

What is the lug width of the Tissot T-Trend T004.309.11.030.00?

The lug width of the Tissot T-Trend T004.309.11.030.00 is 20 millimetres. This measurement is critical for aftermarket strap compatibility and should be measured precisely using a digital calliper positioned perpendicular to the case plane, at the innermost point of the lugs.

How do I change the strap on a Tissot T-Trend T004.309.11.030.00?

Strap replacement requires a spring bar tool. After carefully removing the original spring bar mechanism, insert the new strap into the case lugs. Given the integrated lug geometry of this model, we recommend professional assistance from a certified watchmaker to prevent damage to the case.

Which aftermarket strap is compatible with the Tissot T-Trend T004.309.11.030.00?

All straps with a 20-millimetre lug width are compatible with the T004.309.11.030.00. Milano Straps artisanal straps, available in leather, NATO, and rubber, are certified for this specification and fully customisable to your colour and material preferences.

What is the typical lifespan of a leather strap on a Tissot T-Trend?

A high-quality leather strap, crafted with vegetable or shell cordovan tanning, maintains full functionality and aesthetic appeal for 3–5 years under moderate daily use. Longevity depends on tanning method, frequency of wear, and climatic conditions. Leather develops a natural patina that, with proper care, enhances its visual character over time.
