The Heritage

The Vacheron Constantin Overseas represents the sporty line of the Geneva-based manufacturer, characterized by the hexagonal bezel and robust construction. The model is equipped with the in-house caliber 5300 with indication of hours, minutes and small seconds. The case features the characteristic design with integrated lugs and coordinated metal bracelet.
Made to Measure

The strap for this watch is made to measure

On the Vacheron Constantin Overseas 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 strap be fitted to the Vacheron Constantin Overseas 2305V/100A-B078?

An off-the-shelf strap cannot be attached to this model: the lug area is an integral part of the case design and does not feature a conventional straight-bar fitting. A strap is nonetheless achievable, provided it is built to measure directly on the watch by <a href="/pages/casati-booking">Casati Milano</a>, after recording the precise dimensions of the attachment geometry. The result is a strap that integrates with the case with the same coherence as the original bracelet.

How does the bespoke strap-making process work for this model?

The craftsman at Casati Milano receives the client in the atelier by appointment and physically takes the watch in hand to record every curve and angle of the lug area. A strap is then built specifically for that individual piece, with the leather, colour, buckle and keeper chosen together during the session. Stitching is executed in saddle stitch and every finishing detail is completed by hand before delivery.

Which leather best suits the character of the Vacheron Constantin Overseas 2305V/100A-B078?

The Overseas expresses a dual nature — refined in proportion, sporting in DNA — that translates well into leathers capable of the same ambivalence. Smooth calf with a polished finish accompanies the case in formal contexts, complementing its mirror-polished surfaces. Low-lustre Mississippi alligator introduces texture without competing with the octagonal bezel, while untreated barenia calf develops over time a patina that records daily wear.

How long does a well-made bespoke strap last?

A strap built from first-selection leather, saddle-stitched and fitted with a quality steel buckle can withstand many years of daily use, provided it is kept away from water and rotated with other straps. Longevity also depends on the chosen leather: vegetable-tanned leathers such as barenia tend to improve with wear, developing a patina that increases the character of the piece. The atelier also advises on care and storage during the fitting appointment.

What makes the Vacheron Constantin Overseas 2305V/100A-B078 distinctive among luxury sports watches?

This reference stands out for its 37mm diameter — unusual in a segment where the trend favours larger cases — a decision that prioritises proportion over statement. The calibre 5300 is an in-house movement with small seconds at six o'clock, a technical detail that gives the dial a classical reading within a sporting context. The steel case with octagonal bezel — a direct quotation of the Maltese Cross — ties every element to a precise iconographic history rather than a passing trend.
