Octo 103890

No, the integrated bracelet attachment is proprietary and incompatible with conventional straight spring bars. However, a genuinely bespoke strap – crafted specifically for the watch – represents the authentic artisanal solution. <a href="/pages/casati-booking">Casati Milano</a> develops these straps in-house, measuring the lug configuration directly on the case and ensuring construction coherent with the Octo's geometric vision.

The craftsman at <a href="/pages/casati-booking">Casati Milano</a> meets the client by appointment and performs precise measurement of the proprietary lugs directly on the watch. Subsequently, the strap is constructed according to those dimensions and the case geometry, with selection of leather, thickness, buckle, and finish. The result is a unique, non-interchangeable accessory that fully integrates the character of the timepiece.

The minimalist and geometric character of the Octo demands fine-grained leathers – aged chromium-tanned calf, superior suede, vegetable-tanned skins in sober tones (dark brown, black, taupe). Polished exotics (ostrich, alligator) are appropriate provided they do not introduce texture competing with the case's faceting. Leather must remain subordinate to the watch's design, never the protagonist.

A strap constructed by experienced craftsmen using superior-grade leathers and sound sartorial techniques lasts 8–12 years of regular wear, often longer. The patina the leather develops over time adds aesthetic and intrinsic value. Periodic maintenance (cleaning, conditioning) extends the accessory's lifespan considerably.

The Bulgari Octo 103890, with its BVL 318 column-wheel movement and 110 faceted titanium edges, is a design object where every element serves a unified vision. A standard strap would fail to honour this coherence; a bespoke one, conversely, extends the case's geometric logic to the wrist, completing the tactile and visual experience of the watch.
