Strap for Le Locle Powermatic 80 39.3 Stainless Steel / Silver / Bracelet

The lug width of the Tissot Le Locle T006.407.11.033.00 is exactly 19 millimetres. This measurement is specific to this model and does not align with the more common 18 or 20 mm standards. It is essential to verify that the strap is precisely cut to 19 mm to ensure correct installation on the case lugs, preventing looseness or forced fitting.

For the Tissot Le Locle T006.407.11.033.00, alligator leather is recommended for formal occasions, vegetable-tanned calf leather for daily versatility, NATO nylon for sporty contexts, and FKM rubber for humid environments. The choice depends on the intended use and aesthetic preference. Alligator conveys sober elegance, vegetable-tanned leather develops natural patina over time, NATO introduces colour contrast, and rubber offers practical durability.

To change the strap, the spring bars (suspension pins) must be removed from the case. A specialized tool—typically a thin metal rod—is used to push the pin and extract it from its seat. Once removed, the old strap is disconnected and the new strap is positioned, aligning its holes with the pins. The pins are then reinserted into the seats. The operation requires care to avoid scratching the case.

Yes, aftermarket straps are compatible if cut to a 19 mm lug width. Standard straps of 18 or 20 mm cannot be used without compromising fit or damaging the case lugs. It is mandatory to confirm with the manufacturer that the strap is specifically constructed for this lug width. High-quality bespoke straps are available from specialised ateliers.

The lifespan of a leather strap depends on material quality, frequency of use, and environmental conditions. A high-quality artisanal alligator or calf leather strap can last 3–5 years under intensive daily use. Vegetable-tanned leather typically develops natural creasing after 4–6 years, a phenomenon representing ageing rather than deterioration. Regular maintenance, such as cleaning with a soft damp cloth and occasional application of protective creams, extends the strap's longevity.
