Quick TakeFeast your eyes on a mechanical marvel that redefines the regulator! The Chronoswiss Open Gear ReSec in radiant 18k red gold isn't just telling time; it's putting on a show. Forget subtle – this 44mm beauty demands attention. The hand-guilloché dial provides a mesmerizing, textured backdrop for the real stars: the exposed gear train at 12 o'clock and that hypnotic retrograde seconds hand at 6. Watching it sweep across its arc and snap back to zero is pure kinetic delight. Chronoswiss built this stunner with a complex, multi-level dial – 42 parts, can you believe it? – giving it incredible depth. It’s like peering into a tiny, gilded engine room. The polished and satin-finished red gold case, the tactile knurled bezel, the signature onion crown – it all speaks to meticulous craftsmanship. Limited to just 50 pieces, wearing this isn't just owning a watch, it's possessing a rare piece of horological theatre, powered by the reliable C.301 automatic movement and finished with an exotic Hornback croc strap. It’s bold, technically fascinating, and undeniably luxurious.

DescriptionThe Open Gear ReSec, reference CH-6921R-GRSI, represents a significant development for Chronoswiss, marking the debut of an automatic regulator within a 44mm case dimension. Constructed from 18-karat red gold, the 17-part case exhibits a combination of finishes: surfaces are partly polished and partly treated with a vertical satin finish. Dimensional specifications include a 44mm diameter and a height of 13.35mm. Securing the case is a screw-down back featuring a satin finish and an integrated sapphire crystal for movement observation. The bezel, also screw-down, is polished, incorporating a full thread design and distinctive side knurling; it houses a curved sapphire crystal treated with a double anti-reflective coating. Water resistance is rated at 10 bar, equivalent to 100 meters. An onion-style crown facilitates winding and setting operations. The lug spacing accommodates a 22mm band width.

Powering the CH-6921R-GRSI is the Caliber C.301 automatic movement, operating at a frequency of 4 Hz (28,800 A/h) and providing a power reserve of approximately 42 hours. This intricate mechanism incorporates 33 jewels. Finishing details within the movement include a polished pallet lever, escape wheel, and screws, while the bridges and plates are adorned with perlage. The rotor is skeletonized and red gold-plated, featuring Côtes de Genève decoration and utilizing a ball bearing system for efficient winding. The dial is a highly complex, 42-part assembly constructed on two distinct levels. The lower level showcases intricate hand-guilloché work. The upper level is characterized by screwed-on skeletonized train wheel bridges, a funnel-like structure framing the hour display, and the retrograde seconds mechanism. Time indication follows a regulator format: off-centre hours are displayed at the 12 o'clock position incorporating the "open gear" aesthetic, central minutes are indicated conventionally, and retrograde seconds are presented at the 6 o'clock position. Cylinder-shaped indexes filled with Super-LumiNova enhance low-light legibility. The "Trigono" shaped hands are red gold-plated and polished (or lacquered), featuring Super-LumiNova inlays and tips. This model is strictly limited to 50 units worldwide.
