Quick TakeTalk about a blast of arctic cool on the wrist! The Delphis Sub Zero isn't just blue; it's ice blue, thanks to that deep CVD coating over the entire steel case. It feels substantial, purposeful. But then you look closer, and the dial just pulls you in. That hand-guilloché work isn't just texture; it's like staring into the facets of a glacier, especially on the upper dial and the small seconds subdial, shimmering under the sapphire crystal. The way it displays time is pure Chronoswiss theater: the hour snaps instantly in the window at 12, while the big central minute hand sweeps across its arc before flying back to zero. It's mesmerizing to watch. Down at 6, the little seconds hand keeps a steady beat on its own beautifully textured stage. Limited to just 50 pieces, wearing this feels like belonging to an exclusive club that appreciates intricate mechanics wrapped in a defiantly modern, chillingly beautiful package. It’s a technical conversation starter that doesn't need to shout.

DescriptionThis timepiece, designated Reference CH-1426.1-BKSI, is presented as the Delphis Sub Zero model, constrained to a production run of 50 units globally. The external housing comprises a solid, 17-piece stainless steel construction, subjected to a blue Chemical Vapor Deposition (CVD) coating process. Case surfaces undergo both cutting and polishing treatments. A polished bezel incorporates a side-fluted decorative ring. Protection for the dial is afforded by a cambered sapphire crystal, enhanced with double anti-reflective coating. The case back is secured via screws, features a satin finish, and incorporates a sapphire crystal window for movement observation. Water resistance is rated at 10 bar, equivalent to 100 meters, ensured partly by the screw-down onion-style crown. Strap attachment utilizes a screw-down mechanism featuring Chronoswiss' patented autobloc system. Overall case dimensions measure 42 mm in diameter and 14.5 mm in height, with a lug width of 22 mm. The accompanying strap is fabricated from rubber, color-matched to the case.

Internally, the watch operates on the Chronoswiss manufacture caliber C. 6004, an automatic movement measuring 33 mm in diameter. It incorporates 37 jewels and operates at a frequency of 4 Hz, corresponding to 28,800 semi-oscillations per hour (A/h). The power reserve is specified as approximately 55 hours. Key components include a three-legged Glucydur balance and a Nivarox 1 balance spring. Fine adjustment is achieved via an excenter mechanism, and shock protection is provided by the Incabloc system. Visible through the case back is a skeletonized rotor constructed from tungsten, utilizing a ball bearing system. Further finishing details include polished armature, escape wheel, and screws, alongside a ruthenium-plated bridge decorated with a Geneva cut pattern. Time indication deviates from traditional layouts, employing a digital jumping hour displayed in an aperture at the 12 o'clock position, a central retrograde minute hand, and an analog small seconds display located at the 6 o'clock position.
