Late 19th-century Swiss double watch by C.H. Calame, Genève, housed in an XRF-confirmed 18K yellow gold 53 mm hunting case. The richly hand-engraved case features dense foliate scroll decoration surrounding a vacant shield-shaped cartouche, while the opposing cover is engraved with a finely executed pastoral scene. The movement is signed “C.H. Calame, Genève” and further engraved “Detached Lever, Observation Piece, 21 Jewels, Parachute & Compensation,” reflecting the high-grade construction associated with Swiss precision watchmaking of the period. The watch incorporates a dual-time display with two independent Roman numeral dials on a gilt engine, an uncommon complication intended for tracking two time zones or local and reference time.

Diameter: 53 mm. Weight: 103 grams
