Quick TakeTalk about a showstopper! The Chronoswiss Open Gear ReSec Paraiba isn't just telling time; it's putting on a performance. That hand-guilloché dial is pure magic, shifting from turquoise to green to purple like light hitting a rare gemstone – perfectly named after the Paraiba tourmaline. It's mesmerizing. Then you notice the mechanics dancing right there on the dial: the off-center hours spinning within that cool funnel, the exposed gear train giving it that 'Open Gear' edge. And the seconds hand? It doesn't just sweep; it snaps back! The retrograde seconds at 6 o'clock add a playful complication that's just plain fun to watch. It’s housed in a solid 44mm steel case that feels substantial, balanced by the intricate details like the knurled bezel and onion crown. Even the automatic movement inside gets dressed up with a turquoise rotor. Limited to only 50 pieces, wearing this feels like being part of an exclusive club that appreciates serious watchmaking with a huge dose of personality. It’s technical brilliance wrapped in vibrant artistry.

DescriptionThis timepiece, reference CH-6923-TUBK, features a robust case constructed from stainless steel, assembled from 17 individual components. The case possesses a diameter measurement of 44 millimeters and a vertical height of 13.35 millimeters, establishing a significant wrist presence. Its finish incorporates both polished and vertically satin-finished surfaces, providing visual contrast. An onion-style crown facilitates winding and setting operations. Affixed to the case is a polished, screw-down bezel characterized by a full thread and distinctive side knurling. Protecting the dial is a curved sapphire crystal treated with double anti-reflective coatings to enhance legibility under various lighting conditions. The case back is a screw-down type, featuring a satin finish and an integrated sapphire crystal window, permitting observation of the movement within. Water resistance is rated at 10 bar, equivalent to a depth of 100 meters, ensuring suitability for surface water activities. Lug width is specified at 22 millimeters, accommodating the included strap.

Powering the Open Gear ReSec Paraiba is the Chronoswiss Caliber C.301, an automatic self-winding mechanical movement. This caliber operates at a frequency of 4 Hz, corresponding to 28,800 vibrations per hour (A/h), which contributes to the smooth sweep of the central minute hand and the precise functioning of the retrograde seconds. The movement incorporates 33 jewels to minimize friction at critical points, enhancing longevity and efficiency. Its power reserve is approximately 42 hours when fully wound. Movement finishing includes polished surfaces on the pallet lever, escape wheel, and screws, while the bridges and plates exhibit perlage decoration. A notable element visible through the case back is the skeletonized rotor, which features a turquoise Chemical Vapor Deposition (CVD) coating, Côtes de Genève striping, and utilizes a ball bearing system for efficient winding. The dial presentation is exceptionally intricate, comprising a 42-part construction arranged on two distinct levels. The lower level serves as the canvas for the hand-guilloché pattern, responsible for the dynamic color-shifting effect reminiscent of Paraiba tourmaline. The upper level incorporates screwed-on skeletonized train wheel bridges and features a funnel-like structure for the off-center hour display positioned at 12 o'clock, characteristic of the "open gear" design. Central minutes are indicated conventionally, while a retrograde seconds display arcs across the 6 o'clock position. Time indication is facilitated by lacquered "Trigono" shaped hands, which include Super-LumiNova inlays and tips for low-light visibility, complementing the cylinder-shaped Super-LumiNova hour indexes. The watch is secured to the wrist by a hand-sewn Hornback crocodile leather strap paired with a stainless steel folding clasp. Production of this model is strictly limited to 50 units worldwide.
