Quick TakeForget subtle hints of mechanism; the ReSec Paraiba throws the engine room doors wide open! This isn't just a watch; it's a mechanical spectacle for your wrist. The way Chronoswiss engineered this regulator display is pure theatre – hours perched up top, minutes commanding the center stage, and those seconds doing a captivating retrograde sweep at 6 o'clock. But the real star is the "Open Gear" design. Forget a tiny aperture; here, the bridges and funnels are part of the show, drawing your eye deep into the intricate workings, all set against that stunning hand-guilloched backdrop evoking tropical waters. It’s like having a tiny, intricate machine sculpture that also happens to tell time with Swiss precision. The pops of green on the rotor, visible through the back, echo the dial's theme. It's bold, technically fascinating, and with only 35 ever made, it’s a slice of horological artistry that’s as exclusive as it is mesmerizing. It's less about telling time and more about celebrating the how of timekeeping.

DescriptionThe timepiece reference CH-8753.1-TUBK4 incorporates a case constructed from stainless steel, comprising 16 individual parts. Its diameter measures 41 mm, with a height of 13.85 mm and a lug width accommodating a 21 mm band. The case finish employs a combination of polished surfaces and areas with a vertical satin finish. An onion-style crown facilitates winding and setting operations. Securing the exhibition case back is a screw-down mechanism, featuring a satin finish and an integrated sapphire crystal, permitting observation of the internal movement. The bezel is a polished, screw-down type, distinguished by a full thread and side knurling, housing 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 during typical aquatic activities short of deep diving. The overall architecture reflects a robust yet refined engineering approach, balancing aesthetic considerations with functional requirements for durability and viewing clarity.

Powering this instrument is the automatic Caliber C.299 movement, operating at a frequency of 4 Hz, which corresponds to 28,800 alternations per hour (A/h). This movement provides an approximate power reserve of 42 hours when fully wound and incorporates 31 jewels to minimize friction at critical points. Finishing details within the movement include rhodium-plated pallets and bridges adorned with spiral offsets. Screws are either thermally blued or rhodium-plated and polished, adding to the visual refinement. The rotor, responsible for automatic winding, is skeletonized, finished in green, features Côtes de Genève decoration, and utilizes a ball bearing system for efficiency. The dial presents an elaborate, multi-level construction. Its base layer is meticulously hand-guilloched. The upper level features screwed-on, skeletonized train wheel bridges and distinct funnel-like structures framing the hour and seconds displays. Time indication follows a regulator format: off-center hours positioned at 12:00, central minutes, and small seconds displayed via a retrograde mechanism at 6:00. The “Trigono” shaped hands are rhodium-plated and feature Super-LumiNova inlays for legibility in low light; the minute hand is carefully bent by hand. This model is a limited edition of only 35 units. The strap consists of rubber fused with calf leather, is hand-sewn, and secures with a folding clasp.
