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.
VERTICAL TIME
Devoid of a full-sized dial, Time Pyramid reveals a skeletonised movement in the shape of a pyramid. Alternatively, it can be seen as taking the form of an anchor, recalling our Arnold & Son logo and directly referencing John Arnold’s title as a watchmaker for the Royal Navy.
The collection
DEPTH AND SIMMETRY
Featured in a case of 42.5 mm diameter, Time Pyramid collection is brought to life through materials. Red gold (5N) and platinum (PT950) offer precious alternatives, duplicating each colour on the rim of the dial’s hours and minutes. With its play on transparency and a sense of depth and symmetry, Time Pyramid explores every creative field in watchmaking to assert its distinction.
LEGIBLE ARRANGEMENT
Time Pyramid proudly displays the mechanical arrangement of its movement. The balance wheel is located at 12 o’clock. The gear train is beautifully finished with hand chamfering, satin-finished and sunray-brushed wheels, snailed barrels, and blued screws. The calibre’s structure splits in two below a white opal ring, a signature feature of Arnold & Son’s off-centred dials.
aventurine wonder
The expression ‘open-air’ applies literally here, as the glass used for the case-back offers yet another new interpretation by Arnold & Son. Neither transparent nor opaque, it is composed of an extremely thin disc of aventurine glass in what constitutes a first for this iconic material.
