Octo 103750

No, the integrated bracelet is part of the case geometry and the attachment is not compatible with standard straight-bar straps. However, a custom strap built directly on the watch represents the authentic solution for those seeking alternatives to the original bracelet. <a href="/pages/casati-booking">Casati Milano</a> creates artisanal straps that respect the architecture of the Octo 103750.

The artisan at <a href="/pages/casati-booking">Casati Milano</a> takes precise measurements of the attachment directly on the watch, designs a strap that complements the octagonal form of the case, and constructs it by mounting it repeatedly on the Octo until perfection is achieved. Every keeper, every stitch, every transition is calibrated to the actual geometry of the 103750.

Textured leathers with natural grain—vegetable-tanned calf, vintage leather—dialogue better with the architectural language of the watch than smooth, uniform hides. Neutral colours such as deep brown, intense black, storm grey maintain the sobriety of the design; warm tones like cognac work when the leather possesses sufficient body and texture.

An artisanal strap created with quality leathers, proper stitching and traditional methodology ages gracefully with proper care. Longevity depends on daily wear, exposure to moisture and light, but vegetable-tanned leather can last years, developing a patina that narrates the passage of time, just as the titanium of your Octo does.

Designed by Gérald Genta in 2012, the Octo is a manifesto of architectural geometry where every element obeys a rigorous constructive logic. A custom strap that respects this design intention transforms the strap from a simple accessory into an element coherent with the visual and constructive identity of the watch.
