Strap for Carrera Calibre 16 Day-Date 43 Titanium PVD / Black / Alligator

The lug width of the TAG Heuer Carrera CV2A81.FC6237 is precisely 20mm. This measurement refers to the internal space between the case lugs, and it is critical for strap compatibility. To measure correctly, position a digital calliper perpendicular to the inner edge of each lug, disregarding the curvature of the case.

Vegetable-tanned alligator is the most balanced choice for this model: its fine and regular grain dialogues elegantly with the brushed titanium case surface, and the patina that develops over time adds character without compromising functionality. Alternatively, structured calf leather or shell cordovan offer exceptional rigidity and durability. For more direct sporting applications, NATO straps in premium fabric or high-quality FKM rubber keep the case lightweight and versatile.

The CV2A81.FC6237 features integrated lugs, which means the strap does not attach via standard lateral lugs but rather slots directly into the recesses of the case. To replace the strap, specific tools (spring bar remover or precision screwdriver) are required to carefully release the internal supports. We recommend entrusting this operation to a professional watchmaker or requesting strap change services from Casati Milano atelier, which provides specialised assistance.

Yes, you can use any certified aftermarket strap with 20mm lug width. On milanostraps.it you will find a curated selection of compatible straps crafted from alligator, calf leather, shell cordovan and technical materials, all customisable in size, colour and details. The important thing is to verify that the strap has been constructed with tolerances that respect the attachment dimensions, to avoid lateral movement or excessive compression.

A quality leather strap, crafted with vegetable tanning and artisanal construction, has an average lifespan of 3-5 years with regular daily use. Longevity depends on: frequency of use, exposure to moisture and perspiration, maintenance (periodic cleaning with damp cloth, avoiding prolonged immersion), and leather type. Vegetable-tanned alligator tends to last longer than calf thanks to its density. The Casati Milano atelier offers an 18-month warranty on bespoke straps, with refurbishment and maintenance options in subsequent years.
