The HYT S1 Titanium Japan Limited Edition, reference H03300-A, is an eight-piece Japan-exclusive sports watch with a distinctive black-fluid retrograde hour display. It pairs a satin-finished titanium case with an open-worked, monochromatic dial and a hand-wound movement. HYT lists its suggested price as CHF 58,000 excluding taxes.
What makes the Japan Limited Edition distinctive?
The defining feature is its fluidic hour display: black liquid moves through a borosilicate capillary tube to indicate the hours, with the indication returning retrograde at the end of its cycle. Central minutes and a separate power-reserve hand complete the display. The open-worked dial area, honeycomb-structured flange and Arabic hour numerals keep the mechanism prominent within a silver, black and anthracite palette.
HYT describes the S1 Titanium Japan Limited Edition as the first in a forthcoming series of its sports watches. The edition is limited to eight pieces and, according to the manufacturer, available exclusively in Japan. These are brand-stated edition and distribution details, not evidence of current stock.
Case, dial and dimensions
The case is silver and black coated, satin-finished titanium, with a titanium crown and anti-reflective sapphire crystal. HYT lists anthracite DLC and rhodium-plated brass dial elements, black DLC-plated appliques, white decals and white Super-LumiNova.

HYT says the case and angled strap arrangement are designed to sit stably and comfortably on the wrist. That is the manufacturer’s design claim; the published specifications do not establish a measured fit or independent wear assessment.
How the movement works—and what it specifies
A manually wound calibre 501-CM drives the watch. HYT describes paired small bellows that move the liquid through the capillary; on its English product page, the brand says their walls are one-quarter the thickness of a human hair. That figure is HYT’s description, not an independently verified measurement.

How it fits within the S1 range
HYT’s S1 collection includes other color and finish variants. The Japan edition’s clearest identifying details are its black liquid, silver-and-black coated titanium case and eight-piece Japan-exclusive run. A full, contemporaneous comparison of other S1 models and their prices is not established by the cited product information, so the Japan edition should not be described as technically superior to them.
