Strap for Le Locle Automatic

The lug width (or ansa width) of the Tissot Le Locle T41.1.423.53 is 20 millimetres. This dimension is specific to this model and is critical when selecting a replacement strap, as a 20mm strap ensures proper fitment without structural strain on the case lugs.

For the Le Locle T41.1.423.53, we recommend straps in vegetable-tanned leather (calf, deer) in cognac or dark brown tones, or authentic alligator in black. These materials honour the historical essence of this timepiece. For intensive daily wear, vulcanised rubber delivers practicality and thermoregulation. NATO straps in robust weave offer chromatic versatility and convenient quick-change functionality.

To replace the strap, you must extract the spring bars (lugs) from the case using a dedicated, precision tool. Position the spring bar's internal detent facing downward, apply gentle pressure to release the bar from the case hole, then repeat on the opposite lug. Insert the new 20mm strap equipped with fresh spring bars, then realign the bars into the case holes with a gentle reverse motion until they click securely into position. We recommend using proper watchmaker tools and, if uncertain, consulting a qualified horological workshop.

Yes, aftermarket straps are compatible provided they strictly conform to the 20mm lug width specification. Always verify technical dimensions with the supplier prior to purchase. A high-quality aftermarket strap in genuine vegetable-tanned leather or alligator often develops superior patina and longevity compared to standard factory straps.

A premium vegetable-tanned leather strap typically lasts 3 to 5 years under regular daily wear, assuming proper maintenance (protection from excessive moisture, careful drying post-humidity exposure, occasional application of natural conditioning balms). Vegetable-tanned leather ages consciously: structural decline is gradual. Initial signs of wear (surface creasing, edge abrasion) do not cause sudden failure, thus allowing planned, timely replacement.
