S1 Beadblasted
TITANIUM BLUE

The S1 Blue is our calmest S1, a deep‑focus take on fluidic time for everyday wear..

The S1 Beadblasted Titanium Blue channels HYT’s hydromechanical technology into its most understated S1 expression. It is the cool, focused member of the family – built for daily wear, but with a quietly radical way of showing time.
Its silver and black bead‑blasted titanium case softens reflections and emphasises the architecture of the openworked movement. Against this mineral backdrop, the blue fluid inside the borosilicate capillary floats like a neon ring in zero gravity, while rhodium‑plated markers and white SLN keep everything instantly legible.
Inside beats the hand‑wound 501‑CM calibre, a 352‑component engine with 72 hours of power reserve and HYT’s patented fluidic hours system using two immiscible liquids in a 0.8 mm glass tube. The blue meniscus sweeps around the dial over 12 hours before snapping back in a retrograde motion, a technical signature protected by multiple patents.
A 45.30 × 17.20 mm titanium case keeps weight low and comfort high, with ergonomically sloping sides and steep strap attachments that hug the wrist. The blue rubber strap extends the colour of the liquid, as if the fluid were spilling out of the tube, and can be swapped in seconds thanks to HYT’s quick‑release system.
