Quick TakeForget hiding the mechanical magic; the Chronoswiss Flying Regulator Open Gear CH-8753-BLBL puts its heart right on display! Those meticulously skeletonized, blue-finished bridges and visibly rotating gears aren't just cogs in the machine; they are the main attraction, a dynamic stage built directly onto the dial. The deep blue backdrop creates a contemporary vibe for the time-honored regulator format: hours command attention up top, the central minute hand sweeps with authority, and the small seconds subdial at 6 o'clock pulses with life, marked by a vibrant red hand. It's less a watch dial, more a miniature kinetic sculpture. The robust 41mm stainless steel case, complete with its knurled bezel and reassuring 100-meter water resistance, anchors the artistry. Finished with a hand-sewn blue alligator strap, this timepiece masterfully balances intricate horological craft with an undeniably captivating and interactive character. It doesn’t just tell time; it performs it.

DescriptionThe case construction utilizes stainless steel, assembled from a total of 16 distinct components to achieve its final form. Measurement specifications indicate a case diameter of precisely 41 millimeters, providing a substantial yet wearable presence on the wrist. The vertical dimension, or height, is recorded at 13.85 millimeters, contributing to its profile. Lug spacing is designed to accommodate a strap or bracelet with a width of 21 millimeters. Surface treatment of the case employs a combination of finishes: specific areas receive a high polish, while others are treated with a vertically oriented satin finish, creating visual contrast and texture. A defining characteristic is the inclusion of an onion-style crown, facilitating time-setting and winding operations. The case integrity is further ensured by a screw-down case back, which itself features a satin finish complementing the overall aesthetic. This case back incorporates a sapphire crystal window, allowing direct viewing of the internal mechanism. The bezel component is also of a screw-down design, characterized by a polished surface, a full-thread engagement system for secure mounting, and distinctive side knurling for tactile grip and visual detail. Protecting the dial assembly is a curved sapphire crystal treated with an anti-reflective coating to minimize glare and enhance legibility under various lighting conditions. The structural design achieves a water resistance rating of 10 bar, certified for depths up to 100 meters, ensuring protection against water ingress during typical aquatic activities.

Internal operation is governed by the Chronoswiss Caliber C.299, an automatic winding mechanical movement. This caliber functions at a standard frequency of 4 Hertz, equating to 28,800 vibrations per hour, which contributes to the smooth sweep of the seconds hand and overall timekeeping precision. The mainspring, when fully wound, provides a power reserve estimated at approximately 42 hours. Within the movement architecture, 31 jewels are strategically placed to reduce friction at critical pivot points, enhancing longevity and efficiency. Finishing details applied to the movement components are meticulous: the pallet is rhodium-plated and features spiral offsets, the bridges exhibit circular graining (perlage), and the screws are either thermally blued to achieve a specific color or polished to a high sheen, depending on their location and function. A significant element visible through the case back is the rotor, responsible for automatic winding; it is heavily skeletonized for visual interest, treated with a galvanic blue coating, engraved with traditional Geneva Stripes decoration, and mounted on efficient ball bearings for efficiency. Further refinements visible include a polished finish applied to the pallet lever and escape wheel, key components of the escapement system, along with polished screws securing various parts. Bridges and plates also receive perlage decoration, adding depth to the movement's visual landscape.

The dial construction is notably complex, engineered on two distinct levels to create depth and visual hierarchy. The foundational level consists of a galvanized silver base, providing a backdrop for the upper elements. This upper level is characterized by the prominent mounting of skeletonized train wheel bridges, secured by screws, which form an integral part of the "Open Gear" aesthetic. Additionally, funnel-like structures are incorporated at the hour and second positions, drawing focus to these displays. Time indication adheres strictly to the regulator principle, separating the primary time units for clarity: hours are displayed off-center in a subdial located at the 12 o'clock position, minutes are indicated by a large central hand, and running seconds are shown in a small subdial positioned at 6 o'clock. The hands specified are of the "Feuille" or leaf shape. They are fabricated with a rhodium-plated finish and polished surfaces. For low-light visibility, Super-LumiNova material is applied as an inlay. A specific detail involves the minute hand being carefully bent by hand to follow the curvature of the dial or crystal. The small seconds hand is distinguished by being painted red, adding a contrasting highlight to the display. Completing the watch is a strap crafted from Louisiana alligator leather, which is hand-sewn to ensure quality and durability. This strap is fastened to the wrist using a stainless steel folding clasp mechanism for security and ease of use.
