Strap for Chemin Des Tourelles Powermatic 80 COSC 42 Stainless Steel / Yellow Gold PVD / Silver / Bracelet

The lug width is 21mm. This measurement is critical for strap compatibility: any aftermarket strap must have an internal width of exactly 21mm to fit correctly into the case lugs. Do not confuse this dimension with strap thickness (typically 1.6–2mm): these are independent measurements.

To enhance the yellow gold without visual competition, we suggest alligator leather in cognac or dark brown tones, or burgundy shell cordovan. For a more versatile option, vegetable-tanned calf leather ages beautifully and develops a patina that complements the metal naturally. For daily sporty use, a Cordura NATO in sand maintains elegance without ostentation.

The Chemin Des Tourelles features fixed lugs: strap changes require specialist tools (lug punch and small hammer) and skill. We recommend professional assistance—the Casati Milano atelier (by appointment) handles the change with precision, avoiding scratches to the yellow gold. Alternative: purchase a strap with external passant, less elegant but reversible without tools.

Yes, provided it strictly adheres to the 21mm lug width specification. Quality aftermarket straps from specialist manufacturers often exceed OEM Tissot standards: superior leather, better finishing, artisanal craftsmanship. Always verify technical specifications and contact the retailer if uncertain before purchase.

A premium leather strap (alligatore, shell cordovan, vegetable-tanned calf) worn daily with reasonable care lasts 4–6 years. Critical factors include: climate (humidity accelerates wear), perspiration, direct sunlight exposure, and regular cleaning. Vegetable-tanned leather ages better than alternatives, developing patina rather than deterioration. NATO and rubber straps last 2–3 times longer, though less elegant in formal contexts.
