The Heritage Deck takes its name from the deck watches carried aboard 19th-century surveying vessels — large-diameter manual-wind instruments prized for reliability on long voyages. Its defining feature is a linear up/down power reserve indicator that sweeps from 'réserve pleine' at 120 hours to 'réserve' at zero, allowing the owner to track autonomy at a glance without lifting the watch from its storage box.

Each Calibre timepiece is assembled, adjusted, and timed individually in our Geneva atelier. Expected lead time is 4–6 weeks from order confirmation. Complimentary delivery by insured courier.

The 37 mm case diameter positions the Heritage Deck as a refined, understated presence that disappears beneath a cuff. Rendered above against a reference 65 mm wrist — actual fit varies by wrist circumference.

Heritage Deck

Up/Down Power Reserve Indicator

A fan-shaped sector indicator on the dial sweeps from 120 hours (full reserve) to 0 hours (reserve), driven by a differential gear reading off the mainspring barrel arbor.

Surface Treatment

All bridges and plates receive côtes de Genève finishing, perlage, and hand-anglage to the interior angles — invisible to the wearer, essential to the maker.
