This special edition timepiece from HYT H4 collection honours Switzerland based sailing team Alinghi.
The H4 Alinghi is equipped with a light source. Under the rider at 6 o’clock, HYT has concealed two LEDs. Once activated, they flood the entire dial with white light. At night, the red fluid is energised by this light source, becoming perfectly visible. At the same time, the wash of light flows into every nook and cranny of the calibre, literally bringing this skeleton architecture to life, and defying the laws of watchmaking.
The source of energy is purely mechanical. The generator has been nestled between 4 and 5 o’clock. It is invisible, and activated by the push-piece located opposite on the case middle. The process is broadly that of a dynamo: converting mechanical power into light energy. It is the rotation of the push-piece at 4:30 that winds the generator. Pressure on this same push-piece then activates the two LEDs which bathe the Alinghi in a soft white light.
This illumination is possible for a maximum of five seconds, after which the mechanism must be reinitialised. No battery is needed for this process, which is fully mechanical. Three factors made it so tricky to develop: the extreme miniaturisation, the curved shape, and the fact, once again, that no development of this type had ever been achieved before.
The H4 Alinghi, in honour of the eponymous team, will be released using the same base, with a carbon case, red liquid, white light, the team’s logo on the seconds disc and a strap made from sail canvas, with just 25 pieces available.
