Quick TakeForget your standard time-tellers; the Flying Regulator Night and Day is where Chronoswiss really lets its personality shine! That blue dial isn't just a color, it's a multi-layered stage for a fascinating mechanical performance. Your eyes are immediately drawn to that captivating 3D globe spinning at 9 o'clock, charting the sun's journey and the moon's rise – complete with glow-in-the-dark stars! It’s pure charm backed by serious watchmaking. The regulator layout, pushing the minutes to the main dial while tucking hours and seconds away in their own zones, feels both classic and unconventional. Flip it over, and the exhibition back reveals the C.296 automatic movement doing its thing, complete with a cool skeletonized blue rotor. It's got brains and beauty, wrapped in a precisely finished 41mm steel case that feels just right. Strapped on with that plush alligator leather, it’s less a watch and more a conversation piece that happens to tell time brilliantly, day or night.

DescriptionThe timepiece designated CH-8763-BLBL features a case constructed from stainless steel, composed of 16 individual parts. Its dimensional specifications include a diameter of 41 millimeters and a height of 13.85 millimeters, with a lug width accommodating a 21 millimeter band. The case incorporates both polished and vertical satin finishes, complemented by an onion-style crown. A screw-down case back, detailed with a satin finish and fitted with a sapphire crystal for viewing the movement, secures the enclosure. The bezel is a polished, screw-down type characterized by a full thread and side knurling, surmounted by a curved sapphire crystal treated with an anti-reflective coating. Water resistance is rated at 10 bar, equivalent to 100 meters, ensuring protection against water ingress under specified pressure conditions. The attachment system consists of a hand-sewn Louisiana alligator leather strap paired with a folding clasp mechanism.

Powering this instrument is the Caliber C.296 automatic movement, operating at a frequency of 4 Hz, or 28,800 alternations per hour. This self-winding mechanism provides an approximate power reserve of 42 hours and incorporates 31 jewels to minimize friction. Movement finishing includes a rhodium-plated pallet with spiral offsets, circular-grained bridges, and screws finished either by thermal bluing or polishing. A distinguishing feature is the skeletonized rotor, which is blue galvanized, engraved with Geneva Stripes, and mounted on ball bearings for efficient winding. Further refinements encompass a polished pallet lever, escape wheel, and screws, alongside bridges and plates adorned with perlage. The dial presentation is achieved through an elaborate two-level construction. The lower level is blue galvanized and houses the three-dimensional day/night display and a skeletonized small seconds subdial. Positioned above this, the upper level utilizes funnel-like structures for the hours and seconds display areas. Time indication follows a regulator format: off-centre hours are displayed at the 12 o'clock position, central minutes sweep the main dial, small seconds reside at 6 o'clock, a date aperture is located at 3 o'clock, and the prominent 3-D day/night indicator is positioned at 9 o'clock. The hands are rhodium-plated and polished, designed in the "Feuille" shape, with Super-LumiNova applied to the hour and minute hands for low-light visibility. The night portion of the day/night display also features Super-LumiNova coated stars.
