CHRONOMETRY
LONGITUDE
Longitude Titanium is a COSC-certified chronometer with a power-reserve display and an imposing seconds counter paying tribute to John Arnold’s marine chronometers and his decisive role in calculating longitude at sea.
HIGH-SEA CHRONOMETRY
The aesthetics and construction of John Arnold’s marine chronometers were necessarily classic and functional and were adapted to the harsh conditions of the high seas. Longitude Titanium, a contemporary interpretation of the great English watchmaker’s work, coherently combines this naval heritage with a refined design and highly resistant materials. The movement’s ‘chronometer’ certification is an essential addition to this scene, with its historical ties to Arnold’s creations and his quest for accuracy.
NAUTICAL DESIGN
As a natural consequence of this maritime identity, Longitude presents a titanium case whose curves and profile are directly inspired by the design of contemporary sailing boats. The case middle is taut like a ship’s waterline, while the case back is basin-shaped like a keel. The base of the bezel – the ship’s rail – is graduated with 60 notches, echoing the fluted ring of John Arnold’s marine chronometers. The finishes – polished on the flanks and satin-finished on the flat surfaces – continue this high-sea influence. The crown, protected by a shoulder, is screwed down to guarantee water-resistance to 100 metres.
