Frequently asked questions

What is the exact lug width of the Tissot T-Trend T020.109.11.051.00?

The lug width of the Tissot T-Trend T020.109.11.051.00 is 20 millimetres. This measurement represents the distance between the two lugs of the case and is essential for selecting a compatible strap. You can verify it by measuring with a ruler at the point where the lugs connect to the case body, perpendicular to the wrist.

Which strap is most suitable for the Tissot T-Trend T020.109.11.051.00?

The Tissot T020.109.11.051.00 pairs beautifully with straps in alligator leather, calf, shell cordovan, or NATO fabric. For formal wear, we recommend alligator leather in brown or black tones; for versatile daily use, a NATO strap in heavyweight cotton. The choice depends on your usage context and personal aesthetic preferences.

How do I change the strap on a Tissot watch with 20mm lugs?

To change the strap, obtain a quality spring bar removal tool. Position the watch on a stable surface, gently insert the forked tip of the tool beneath the elastic pin of the lugs, apply pressure to compress the spring, and extract the old strap. Repeat for the other lug, then insert the new strap by compressing the springs until you hear a click indicating secure fastening.

Can I use an aftermarket strap on a Tissot T-Trend T020.109.11.051.00?

Yes, any strap with a 20mm lug width is compatible with the Tissot T020.109.11.051.00. Artisan straps produced by specialised workshops often offer superior build quality and advanced aesthetic customisation compared to OEM straps. Always verify that the new strap has an exact 20mm lug width.

How long does a leather strap last on a watch like the Tissot T-Trend T020.109.11.051.00?

Durability depends on the quality of the leather and your usage frequency. An alligator or shell cordovan strap with vegetable tanning lasts an average of 5–8 years of daily wear, developing a natural patina that enhances aesthetic appeal. A common calf strap has a lifespan of 3–5 years. Factors such as humidity, sun exposure, and wearing frequency significantly influence longevity.
