High sea watchmaking with a power reserve display at 12 o’clock and an imposing seconds counter at 6 o’clock, longitude titanium pays tribute to john arnold’s marine chronometers, his revolutionary vision and his decisive role in calculating longitude at sea. 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. 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. With its flowing curves, longitude titanium is both comfortable to wear and a joy to behold. Each of the series is fitted with an integrated titanium bracelet. Everything is rounded with no straight lines, even in the finer details as the links themselves are domed. The succession of gentle curves and combination of polished and satin finished surfaces are a continuation of the case’s identity. Longitude titanium is complemented by an interchangeable system and comes with an additional rubber strap. The dial of longitude titanium has been designed in a graphic and historical spirit.
