T1 5n Gold & Titanium Deep Blue

The T1 SERIES, unveiled in four dazzling references, is a 45mm collection with an octagonal shape and subtly faceted sides.

For the first time in its history, the brand introduces a fully enclosed dial, designed to achieve absolute harmony. This creation stands out with meticulous and ultra-contemporary craftsmanship, featuring circular satin finishes along the minute track and on the hour ring that enhance a sophisticated midnight blue – paired with black tinted fluids. The case is in 5N gold complemented by DLC titanium.

Mechanical components and technological advancements merge in perfect harmony. The watch features a domed ‘bell’ sapphire crystal, treated with an antireflective coating. The open caseback, features an antireflective sapphire crystal to offer a clear view of the intricate workings inside. Here, the HYT’s mechanism is powered by the two hallmark pistons that regulate the movement of fluids under the impulses of the manually wound caliber 501-CM, itself composed of 352 parts. Thoughtfully designed for ergonomics and positioned at 2 o’clock, the torque crown is key to ensuring water resistance up to 50 meters, merging functionality and aesthetics with flawless reliability and precision.

The time display, specific to HYT and calibrated for 12 hours, combines the fluidic hour indication – via the liquid-filled glass capillary along an outboard scale from 6 o’clock to 6 o’clock – with a mechanical minute indication via a central hand sweeping around an inboard minute track.

Specifically, a tinted liquid progressively fills the capillary, marking the hour against the outboard scale along the dial’s flange. After 12 hours, as it reaches the 6 o’clock position on the right, the tinted liquid retrogrades to its starting point at 6 o’clock on the other side. For a precise reading of the time, the minute markers are displayed in Arabic numerals around a dedicated sector on the dial.

The exclusive HYT manufacture caliber beats at 28,800 vibrations per hour, with a 70-hour power reserve indicator at 2 o'clock.

Each reference is offered with two interchangeable rubber straps, each with its own buckle.

The innovative interchangeable strap system, specially designed for the T1 SERIES, required a year of research and development. The strap can readily be clicked in and out by pressing a push-button located on the back in the case middle, precluding inadvertent release. A titanium pin buckle – PVD titanium on the 5N gold/titanium model – adds elegance to a secure fit.

The fundamentals of HYT’s fluidic time display mechanism

HYT watches present a unique blend of science, technology, fine watchmaking, and design. Drawing inspiration from the principle of the clepsydra dating back to the pharaohs, HYT’s mechanism features two flexible reservoirs positioned at 6 o'clock, connected at each end of a capillary. In one, a colored aqueous liquid. In the other, a transparent viscous liquid. The two are immiscible: the repulsive force of the molecules of each fluid makes it impossible for them to mix. Delimiting the boundary between the two: the meniscus.

The fluid reservoirs are actuated by two extremely flexible and resistant bellows made from electro-deposited alloy and driven by pistons. As the reservoir containing the tinted aqueous liquid expands, the other is compressed, and vice versa, enabling the fluids to travel back and forth through the capillary. The system marks the passage of hours by ‘pushing’ the tinted liquid (creating an ever taller column of the fluid in the capillary) and ‘pulling’ the transparent viscous liquid (causing this column of liquid to shrink proportionately). The point where the two liquids meet – the meniscus, in the shape of a half-moon – indicates the hour on the scale. When it reaches 6 o’clock, the column of tinted liquid automatically retrogrades to its initial position. The power to drive the system is generated by a mechanical watch movement.
