Strap for Master Collection 42 Moonphase Stainless Steel / Blue / Bracelet

The lug width is 21mm. It is a specific standard for this model, not particularly common in the aftermarket. To verify dimensions with precision, measure the interior of the lug using a digital calliper from inside to inside: a variation of 0.5mm significantly alters the fit of the strap to the case.

Alligator is the ideal choice from an aesthetic standpoint: the fine, straight grain dialogue with the satin finish of the case, emphasising the tonneau proportion. Recommended colours are cognac for everyday business contexts, black for formal occasions. Shell cordovan is a sophisticated alternative for those preferring English calf leather. We always recommend a deployante clasp for wrist stability.

The lugs of this reference are fitted with standard quick-release passants or fixed rivets, depending on the specific version. If the case has quick releases: press the micro button beneath the lug and slide the strap; the procedure takes about one minute. If riveted: entrust the task to a specialist jeweller or watchmaker to avoid damaging the case. Casati Milano atelier offers a custom change service with warranty.

Yes, provided the lug width is exact (21mm). Always verify the internal dimensions of the lug: thickness of the passant band, length of the strap (must cover at least 70–80% of the lug). Milano Straps artisanal leather straps are crafted to custom specifications with personal choice of leather and 18-month warranty.

An artisanal alligator or shell cordovan strap lasts 4–8 years in daily wear, developing natural patina. Longevity depends on exposure to humidity, perspiration, extreme temperatures. Vegetable-tanned leather ages more visibly, creating vintage effects after 2–3 years. Silicone rubber resists for 5–7 years. Casati Milano atelier provides an 18-month warranty and regeneration service to extend useful life.
