Frequently asked questions

What is the lug width of the Tissot T-Trend T004.309.11.110.00?

The lug width of the Tissot T-Trend T004.309.11.110.00 is 18 mm. This dimension represents the distance between the two lateral attachments on the case and determines compatibility with aftermarket straps. To verify the measurement accurately, position a calliper or rigid ruler between the inner shoulders of both attachments: the resulting value must be exactly 18 mm.

Which strap is recommended for the Tissot T-Trend T004.309.11.110.00?

The Tissot T-Trend T004.309.11.110.00, given its compact dimensions (21 mm case diameter), pairs exceptionally well with fine-grained Italian calf leather for formal daily wear, with genuine alligator for business contexts, or with woven NATO straps for a more contemporary aesthetic. Milanostraps.it's 18 mm collection offers selections in vegetable-tanned leather, shell cordovan, and vulcanised rubber, each designed to enhance the model's minimalist design language.

How do you change the strap on the Tissot T-Trend T004.309.11.110.00?

Changing the strap on the T004.309.11.110.00 requires the use of a spring bar tool (a specific instrument for removing elastic pins). Position the watch on a stable surface, insert the small lever of the tool into the lateral spaces of the attachment, apply gentle pressure to compress the internal elastic pin, and remove the old strap. Insert the new strap (18 mm), aligning the holes with the pins, then snap the pin into position. We recommend performing this operation with care or consulting a specialist service.

Which aftermarket strap is compatible with the Tissot T-Trend T004.309.11.110.00?

All straps with an 18 mm lug width are compatible with the T004.309.11.110.00. Milanostraps.it offers a comprehensive range: Italian leather straps (calf, alligator), shell cordovan straps with vegetable tanning, NATO straps in robust fabric, and vulcanised rubber straps. Each model is tested to guarantee mechanical fit and structural durability over time.

How long does a leather strap last on the Tissot T-Trend T004.309.11.110.00?

The lifespan of a leather strap depends on leather quality, frequency of use, and environmental conditions. An artisanal Italian calf strap, worn under normal conditions (5-7 days per week), maintains structural and aesthetic integrity for 3-5 years. Vegetable tanning develops a natural patina over time that increases aesthetic appeal. Shell cordovan straps, thanks to superior fibre density, can last 6-8 years with minimal maintenance. Prolonged exposure to moisture, direct heat, and aggressive detergents significantly reduces longevity.
