Official description

Hyper-technical, sleek, electrifying – with the new HASTROID Blue Star, HYT yet again pushes the boundaries of materials used in horology. Nonconformists at heart, the pioneers of fluidic time chose magnesium for the case and a subtle metallic blue gradient for the case middle to give this new evolution a head start on modernity. Incredible lightness meets exceptional innovation.

The Hastroid’s case, with a diameter of 48 mm, a lug-to-lug distance of 52.3 mm, and a thickness of 13.3 mm, has so far been crafted from advanced noble materials: titanium; titanium and carbon; and an original alloy of stabilized bronze and carbon that bridges memories of the ages and aspirations for the future.

As an incubator of the unprecedented in watchmaking, HYT thrives on challenges, on pushing the boundaries in the use of modern and unexpected materials. Hence this new limited edition of 20 pieces: HASTROID Blue Star. Watch cases are traditionally made from metals such as stainless steel, gold, titanium or aluminum. The use of magnesium is rare, and its unique properties make it interesting, too. Factoid: magnesium is 2.6 times lighter than titanium, yet extremely strong; at the same time it is extremely difficult to machine for watchmaking applications. A challenge HYT simply had to take on.
