Strap for Nautilus 5713

No. The bracelet is integrated into the case: there is no standard lug to attach an off-the-shelf strap. The fitting is proprietary, conceived by Genta as part of the watch's own architecture. In the atelier I build each strap directly on the case, millimetre by millimetre.

I work by appointment only, at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15, Milan. I bring the watch to the bench, take measurements directly from the white gold case, and build the fitting following the original curves. I do not work from photographs or declared measurements: the watch must be here, in front of me.

I prefer a natural Mississippi alligator, allowed to age gradually without forced colour treatments. White gold has a cool luminosity that pairs beautifully with a warm, lived-in leather. I avoid overly glossy or heavily treated skins: on a watch with this character, I look for continuity, not contrast.

I have seen well-cared-for alligator straps last ten, twelve years of daily wear. Leather asks for very little: keep it away from standing water, condition it occasionally, let it breathe. It ages, of course — but it ages with character, moulding itself to the wrist of the person wearing it.

Genta drew it in 1976 for someone who wanted a robust watch even with a dinner jacket. Today, with its annual calendar and moon phases, the 5713/1G-001 has taken a more contemplative direction. I see it as a refined dress watch that still carries its sporting origins inside, but no longer needs to announce them.
