Arnold & Son introduces the Longitude Titanium 5°W Edition, a limited series of 38 pieces, paying homage to John Arnold’s revolutionary marine chronometers from the 18th century. These historical instruments were crucial for precise maritime navigation. The watch’s design elements evoke the nautical heritage, particularly referencing Lizard Point, Cornwall, a significant landmark for seafarers. The tragic 1707 naval disaster off the Scilly Isles, caused by navigational errors, led to a £20,000 reward from the British Admiralty for an accurate longitude measurement method, which ultimately propelled John Arnold to prominence.

The timepiece is housed in a 42.5mm Grade 5 titanium case, boasting water resistance up to 100 meters and a slim profile of 12.2mm. Its sleek lines and faceted edges are reminiscent of modern sailing vessels. A striking contrast is provided by an 18-karat red gold fluted ring between the case middle and bezel, which secures the slightly domed sapphire crystal. The "Lizard Point Grey" dial captures the essence of the North Atlantic’s metallic hues, while its vertical satin finish subtly mirrors the ocean's waves. Functionally, it features a power reserve indicator at 12 o’clock, a small seconds subdial at 6 o’clock, and skeletonized hour and minute hands with luminous coating for optimal readability in varying light conditions. The watch is powered by the automatic manufacture caliber A&S6302, operating at 28,800 vibrations per hour and offering a 60-hour power reserve. The transparent titanium caseback reveals the intricately finished movement, adorned with palladium-coated, polished, and beveled bridges featuring a 'Rayons de la Gloire' pattern. A 22-karat gold oscillating weight, engraved with a ship’s silhouette and a sextant, symbolizes maritime exploration. COSC-certified, this edition comes with a titanium bracelet and an additional gray leather strap, priced at 29,500 Swiss francs (approximately $34,300 excluding VAT).
