Strap for Calibre 16 Day Date 43 Stainless Steel / Silver / Alligator

The lug width is 20 millimetres. This dimension is specific to the Carrera model in its 43mm version with integrated stainless steel bracelet. The lugs are welded integrally to the case and measure internally from flange to flange. It is essential to verify that the aftermarket strap slides without resistance between the pins, with maximum tolerance of ±0.3 millimetres.

Navy alligator or black alligator represents the most refined pairing, coherent with the blue bezel and dark dial of the chronograph. Alternatively, vegetable-tanned calf leather in dark, matte finish offers daily versatility whilst maintaining formal elegance. Dark mogany shell cordovan is ideal for those seeking superior durability and progressive ageing patina. We advise against polished and smooth straps: the satin geometry of the case requires pronounced textures with visible grain.

Strap replacement requires the use of a spring bar tool to extract the attachment pins. Position the watch on a soft, flat surface, gently withdraw the pins from their seat, remove the old strap and insert the new one. Ensure the replacement strap has a certified 20mm lug width and slides without friction between the lugs. If unfamiliar with the procedure, entrust the task to an expert: Casati Milano atelier provides strap-change service with personalised guidance.

Yes, provided the strap has a certified 20-millimetre lug width. Quality aftermarket straps must respect the ±0.3mm dimensional tolerance and not compromise the structural integrity of the welded attachments. Verify that the strap base slides smoothly between the pins without resistance. Milano Straps offers 20mm straps tested for compatibility with this model, customisable in leather, size and finish.

A high-quality leather strap—alligator, vegetable-tanned calf, shell cordovan—has a lifespan of 3–5 years with average daily wear. Longevity depends on maintenance, direct sun exposure, humidity and frequency of wear. Shell cordovan and alligator straps age more gracefully, developing patina and controlled micro-creasing that increases aesthetic value over time. Casati Milano's 18-month warranty covers construction defects; renewal of finishes (tinting, polishing) is recommended every 18–24 months to preserve original appearance.
