HYT

HYT (Hydro Mechanical Horologists) was founded in 2012 in Neuchâtel by Lucien Vouillamoz, Vincent Perriard, Patrick Berdoz, and Emmanuel Savioz. The concept originated with Vouillamoz around 2002, inspired by the ancient clepsydra, the water clock first devised some 3,400 years ago — but no technical solution existed to miniaturize fluid time display into a wristwatch until Preciflex, HYT's sister company, developed the micro-bellows technology to make it possible. The execution is a genuine first in portable horology: two flexible bellows of immiscible fluids — one fluorescent, one transparent — connected by a hairpin capillary tube roughly 11cm long and 1mm in internal diameter, curving around the entire dial. The bellows walls are a mere quarter the thickness of a human hair yet 10,000 times more watertight than a diver's watch; as the mechanical movement drives them, the meniscus between the two liquids travels around the capillary to mark the hours, retrograding instantly back to its start at the top of each hour. Movement engineering was developed with Chronode under Jean-François Mojon. The debut at Baselworld 2012 won the GPHG Prize for Best Innovative Watch Concept, along with Best Concept Watch honors at SIAR Mexico and the Watch World Awards India. HYT filed for bankruptcy in March 2021 and was acquired the same year by Kairos Technology Switzerland (KTS) SA, relaunching in 2022 with the Hastroid.

Five collections now carry that hydromechanical DNA forward, each pairing the fluidic hour display with a distinct engineering personality. The Conical Tourbillon is HYT at its most ambitious: inspired by Walter Prendel's 1928 inclined-balance tourbillon, its hand-wound 701 TC caliber (61 jewels, 21,600vph, 40-hour reserve) inclines its spring-balance at 30 degrees, its escape wheel at 15, and its pallet at 23, while a hypnotic 'chaotic animation' of liquid-filled spheres — rotating at four, five, and six turns per minute — shares the dial with the fluidic hours; the Midnight Blue reference, cased in 5N gold and black DLC titanium and limited to 8 pieces, sells for CHF 355,000. The Hastroid channels that same engineering into a bolder sport aesthetic — the Silver Red, limited to 15 pieces at CHF 75,000, houses a 41-jewel manual caliber (72-hour reserve) inside a 48mm titanium case with cockpit-style sub-counters for small seconds and power reserve. Moon Runner reinterprets one of watchmaking's oldest complications through HYT's contemporary lens: the Ghost edition (15 pieces, CHF 125,000) sets a hand-painted 3D moon phase, its craters individually rendered in miniature, within a titanium-and-carbon case, driven by a 42-jewel movement with day and month indications alongside the fluidic hours.

The T1 Series, HYT's newest and most wearable line, trades outright spectacle for refinement: a smaller 45.3mm case, a year of R&D behind its push-button interchangeable strap system, and a neo-classical palette exemplified by the Titanium Slate (CHF 48,000) with its circular satin-finished hour ring and blue-tinted fluid. The S1 Series opened a new sports-watch chapter for the brand, debuting with an eight-piece Japan limited edition explicitly built for performance and precision, with further complications planned for the permanent range still to come. Across every collection the underlying promise is unchanged: liquid, not hands, marking the passage of time — a genuinely new time-display medium that remains, more than a decade after its invention, the one mechanism no other watchmaker has replicated.
