Ever since HYT was revived in early 2022, the brand has been incredibly active again, often presenting new and interesting combinations of colours and materials. Everything still revolves around the concept of telling time with liquids, which is a rather contradictory method when it comes to mechanical watchmaking. Next to magnetism, moisture is the biggest threat to the well-being of watches. Nevertheless, the masterminds of HYT found a way to do it, and have introduced various editions of the Hastroid and Moon Runner collections. New to the Hastroid range, HYT’s core model in a way, is the Blue Star, fitted with a lightweight magnesium and titanium case.

HYT is not shy to change things up from time to time by using an unexpected type of material here and there. As said in the intro, for this Hastroid Blue Star, lightweight magnesium was selected for the outer casing, finished in a metallic electric blue. This is combined with black-coated titanium elements, both of which keep the weight of the Hastroid Blue Star down as much as possible despite the rather large dimensions of 48mm diameter, 17.20mm height and 52.30mm lug to lug. The crown is also done in blue magnesium and black titanium. A black side grid with a black background finished it all off.

The dial of any HYT is always a special thing, and the Hastroid Blue Star doesn’t disappoint. The hours are indicated by the two non-miscible liquids inside the capillary. As the liquid is pushed along, the barrier between the two keeps track of the progress of every hour. Once it reaches 6 pm, the liquids are pushed back to the start to start their 12-hour journey once more. The large central hand is used to indicate the minutes and is finished in black and blue with a small white tip. There’s also a black-and-white minute track, finished with a blue outline for an extra bit of colour. The upper half of the dial is also home to a running seconds display on the left and a power reserve indicator on the right.

The movement in the Hastroid Blue Star is unchanged from previous editions. Supporting the overall black and blue colour scheme with blackened plates and bridges, it still relies on the brand’s signature meca-fluidic module fixed to a manually wound mechanical base. This Calibre HYT 501-CM as it’s called, was developed with Eric Coudray and is built up with 352 individual components. The two bellows pump the non-miscible liquids through the capillary, as we explained. You can see most of the movement’s running gear in action, as it beats at a frequency of 28,800vph and has a 72-hour power reserve.

The HYT Hastroid Blue Star is limited to 20 pieces and is delivered with a black and white rubber strap with a black microfibre embossed decoration and blue stitching. Additionally, you also get a white rubber strap with blue leather embossed decoration and white stitching to change up the look. The watch retails for CHF 79,000 excluding taxes.
