Quick TakeForget subtle hints of mechanics; the ReSec Aurora throws the engine room doors wide open! That dial is a playground for the eyes, a multi-level mechanical landscape where the 'Open Gear' concept truly comes alive at 12 o'clock. You see the gears turning, the heart beating, right there under the off-center hours. Then, bam! Your gaze snaps down to 6 o'clock where the retrograde seconds hand performs its lively sweep and jump-back routine every minute – it's pure kinetic theatre. And the colors! The hand-guilloché base provides this incredible depth, contrasted by that vibrant turquoise on the CVD-coated rotor visible through the back. Let's not forget the 'Aurora' aspect – those chunky Super-LumiNova blocks aren't just markers; they're designed to glow intensely, like miniature beacons cutting through the dark. Strapped onto a tough Cordura textile strap with a secure folding clasp, sitting inside that robust 44mm steel case with its knurled bezel, this isn't just a watch; it's a statement piece brimming with technical sophistication and luminous personality, limited to only a lucky 50 wrists.

DescriptionThe Chronoswiss Open Gear ReSec Aurora, reference CH-6923-TUBK2, is presented in a multi-component stainless steel case comprising 17 individual parts. Its dimensions measure 44 millimeters in diameter and 13.35 millimeters in height, ensuring a substantial presence. The case features a combination of finishes, incorporating partly polished surfaces alongside areas with a vertical satin finish. An onion-style crown facilitates time-setting and winding operations. Protecting the dial is a curved sapphire crystal, enhanced with double anti-reflective coating to maximize legibility under various lighting conditions. The bezel is a polished, screw-down type, distinguished by a full thread and side knurling, contributing to the case's structural integrity and aesthetic detail. Water resistance is rated at 10 bar, equivalent to 100 meters, suitable for surface water activities. The case back is secured via a screw-down mechanism, featuring a satin finish and an integrated sapphire crystal window, permitting observation of the internal mechanism. The band width specification is 22 millimeters, accommodating the provided strap.

Powering this timepiece is the automatic Caliber C.301 movement, which operates at a frequency of 4 Hertz, or 28,800 alternations per hour (A/h). This movement provides a power reserve of approximately 42 hours when fully wound and incorporates 33 jewels to minimize friction and wear on critical components. Finishing details within the movement include a polished pallet lever, escape wheel, and screws, while the bridges and plates are adorned with perlage. A distinctive feature is the skeletonized rotor, treated with a turquoise Chemical Vapor Deposition (CVD) coating, decorated with Côtes de Genève finishing, and mounted on a ball bearing for efficient winding. The dial itself represents a complex, 42-part construction arranged on two distinct levels. The lower level showcases hand-guilloché work, providing intricate texture. The upper level features screwed-on, skeletonized train wheel bridges and a funnel-like structure for the hour display, alongside the retrograde seconds mechanism. Time indication employs an off-centre hour display at the 12 o'clock position featuring the "open gear" aesthetic, central minutes, and a retrograde seconds display situated at the 6 o'clock position. Cylindrical Super-LumiNova indexes mark the hours, ensuring visibility in low light. The hands are rhodium-plated "Trigono" style, filled with Super-LumiNova; the minute hand is notably bent by hand. This model is a limited edition of only 50 units.
