Limited Edition of 50 pieces Chronoswiss Watch Flying Grand Regulator Night and Day CH-8763-BLSI Since 1987, Chronoswiss have become synonymous for their regulator watches, a design which sees three separate registers for the hours, minutes and seconds. The Chronoswiss Flying Grand Regulator Night and Day Limited Edition watch takes a spin on this classic aesthetic incorporating a date window and a unique three-dimensional night and day display on a handmade guilloche dial. The domed day and night indicator is placed at 9 o’clock and made of blued titanium. When night falls, the complication reveals a starry sky which glows impressively in the dark thanks to a helping of Superluminova. The elaborate dial continues to impress with a blue guilloche base, skeletonised small seconds and feuille-shaped hour and minute hands contrasting in rhodium-plating. The powerhouse to the Chronoswiss Flying Grand Regulator Night and Day watch is the Calibre C.296 automatic winding movement. Spotted through the exhibition case back, the movement delivers 31 jewels, a rhodium plated pallet, circular grained bridges, and a rhodium-plated Cotes de Geneve oscillating rotor. The Swiss made calibre also guarantees a power reserve of 42 hours and a frequency of 28,800 vibrations per hour. The movement is protected within a 41 millimetre case engineered from stainless steel with curved sapphire crystal glass treated with anti-reflective coating, a screw down bezel and a satin-finished onion-shaped crown water resistant to 100 metres. To match the blue dial, the Chronoswiss Night and Day watch is paired with a hand-sewn Louisiana alligator leather strap in black with subtle blue stitching and a classic stainless steel folding buckle.
