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.
The Nebula origin
The word ‘Nebula’ was chosen to refer to the massive cloud of dust and gas that exists in space. Some nebulas are formed when a dying star, like a supernova, explodes and expels gas and dust. Others are regions where new stars begin to form. The collection features seven bridges on the dial that radiate from the centre, giving the sculptural movement the appearance of a cosmic explosion.
Available in two diameters
Nebula is available in two diameters – 41.5 mm or 38 mm – and is remarkably slim, measuring just 8.73 mm thick. It is crafted from a red gold (5N) block or stainless steel.
The collection
true openworked calibre
The calibre was designed as a skeleton mechanism rather than being modified by removing material. This approach provides an apparent and legible display on both sides, with each component revealing its subtle finishes and adopting strict, fluid forms. These details and the overall approach make it unique, as it is in the exclusive circle of skeleton movements. It offers a total power reserve of 90 hours, requiring only hand-winding every three-and-a-half days. At 4mm thick, the calibre contributes to the collection’s overall slimness, making it a natural member of the ultrathin category.

DSTB
DSTB, which stands for ‘Dial-Side True Beat’, is one of Arnold & Son’s most personal collections, revealing its true-beat second’s mechanism on the dial side.
Ultrathin Tourbillon
Ultrathin Tourbillon is one of the slimmest in the world. Presented in its purest expression, nothing distracts the eye from the hypnotic workings of the one-minute flying tourbillon.
Time Pyramid
By arranging the organs of Time Pyramid‘s movement from top to bottom instead of in a circle, Arnold & Son goes beyond the chronometric horizon to achieve an unparalleled feat of design.
