Made to Measure

The strap for this watch is made to measure

On the Bulgari Octo the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

Can a standard strap be fitted to the Bulgari Octo 103426?

No, a traditional straight-bar strap is not compatible with the integrated lugs of this model. The Octo 103426 requires a bespoke strap, handcrafted directly onto the watch by <a href="/pages/casati-booking">Casati Milano</a>, so that proportions and geometry remain coherent with the case design.

How does the bespoke strap construction process work?

The craftsman at <a href="/pages/casati-booking">Casati Milano</a> examines the watch and precisely measures the lug specifications: angle, functional spacing, volumetric distribution. Based on this anatomical blueprint, the strap is handcrafted using your chosen leather, with personalised stitching and finishing. The result is an element that dialogues perfectly with the titanium case.

Which leather suits the character of the Bulgari Octo 103426?

Given the geometric purity and modern character of the model, we recommend superior-quality Genovese with regular grain, alligator for tactile tension, or ostrich leather for its organic texture that creates fascinating contrast with the octagon. Your choice depends on personal style and intended use.

How long does a bespoke strap last?

A strap crafted with superior-grade leathers and artisanal stitching, as those from <a href="/pages/casati-booking">Casati Milano</a>, maintains excellent condition for several years of regular wear. The patina that develops over time adds character to the leather, while stitching remains robust if the strap is constructed to true craftsmanship standards.

Why is the Bulgari Octo 103426 such a distinctive timepiece?

The Octo 103426 combines octagonal geometry inspired by Roman architecture with contemporary technical purity: ultra-lightweight titanium case, Bulgari calibre BVL 138 movement, proportions that defy aesthetic convention. It is not merely an accessory, but a functional sculpture representing the pinnacle of Italian design thinking in horology.
