Strap for Overseas Date Zürich Boutique Edition

The Overseas bracelet attachment is an integral part of the case design, with a proprietary geometry that does not accept standard straight-lug straps. A strap is nonetheless possible, built to measure directly on the watch by <a href="/pages/casati-booking">Casati Milano</a>, a bespoke atelier operating by appointment. The result is a strap calibrated to the actual dimensions of the attachment, maintaining formal continuity with the original bracelet.

Casati Milano begins with a physical survey of the attachment geometry, carried out directly on the client's watch during the atelier session. From these real measurements — not generic templates — the strap is constructed, with the client choosing leather, colour, buckle or deployant clasp, and stitching style. No stage relies on approximation: every strap is a unique piece calibrated to that specific watch and that specific wrist.

Box calf leather, capable of developing a rich patina through wear, complements the hexagonal bezel and the polished-satin surfaces of the case without competing with them. Fine-grained embossed calf adds visual texture while remaining within the elegant register of the piece. For those who travel frequently and require moisture resistance, quality technical rubber is consistent with the sporting origins of the Overseas line.

A strap crafted from selected leathers with hand-stitching, finished edges, and sewn rather than glued layers will typically last many years, developing a patina that enhances its character over time. Longevity depends on the leather chosen, frequency of use, and basic care. With minimal maintenance — avoiding prolonged exposure to water for untreated leathers, storing in a dry place — a well-made strap can last decades.

The in-house calibre 5100, displaying hours, minutes, seconds and date, brings the level of finishing expected from a Maison with over 260 years of uninterrupted history. Its presence beneath the case gives the Overseas a technical substance that goes beyond its sporting aesthetic: this is a watch intended to be worn continuously, across varied contexts. That versatility calls for straps suited to both a jacket and a jumper, such as box calf or quality rubber.
