Frequently asked questions

What is the lug width of the Tissot T-Trend T004.309.11.110.01?

The lug width of the Tissot T-Trend T004.309.11.110.01 is 20 millimetres. This measurement represents the distance between the two attachment pins (the small bars that pass through the case lugs) and determines compatibility with aftermarket straps. It is essential to verify this dimension before purchasing a replacement strap to ensure a precise fit without play or forcing.

Which strap is most suitable for the Tissot T-Trend T004.309.11.110.01?

For the Tissot T-Trend T004.309.11.110.01, straps that reflect the urban and minimalist nature of this timepiece are particularly appropriate. An alligator strap with vegetable tanning in chestnut brown or black accentuates the case's elegance whilst maintaining visual balance. Calf leather with fine grain offers soft drape and develops a fascinating patina over time. For more casual versions, ballistic textile NATO straps maintain proportions coherent with the watch's compact design, whilst synthetic rubber ensures maximum daily practicality.

How do you change the strap on the Tissot T-Trend T004.309.11.110.01?

To change the strap on the T004.309.11.110.01, you must remove the attachment pins (the small bars passing through the case lugs). Using a spring bar tool, apply gentle pressure to compress the pin's internal spring, then remove the bar from the lug hole. Repeat this operation on the second pin. Insert the new pins into the aftermarket strap, then reposition the watch. If you are inexperienced, consult a professional watchmaker to avoid damaging the case.

Which aftermarket strap is compatible with the Tissot T-Trend T004.309.11.110.01?

All aftermarket straps with a 20-millimetre lug width are compatible with the Tissot T-Trend T004.309.11.110.01. This includes leather straps (alligator, calf, vegetable-tanned leather), textile NATO straps, synthetic rubber straps and shell cordovan straps. Your choice depends on intended use and aesthetic preferences: select natural leather for formal contexts; prefer textile or rubber for daily sporting use. Ensure the strap is specifically designated for 20mm lug width compatibility.

How long does a leather strap last on the Tissot T-Trend T004.309.11.110.01?

The lifespan of a leather strap for the T004.309.11.110.01 varies according to quality and usage patterns. An alligator strap with vegetable tanning maintains structural integrity for 5-8 years of daily wear. Standard calf leather requires replacement every 3-4 years if subjected to intensive use and humid conditions. Leather ageing is natural and creates a fascinating patina rather than deterioration. To extend useful life, store the strap away from direct sunlight, occasionally apply wax-based conditioners, and rotate between multiple straps.
