Quick TakeForget minimalist trends; this Chronoswiss Lunar Chronograph is a celebration of complexity wrapped in luxurious warmth. The 18k red gold case isn't just precious metal; it's the stage for a mechanical ballet. Look closely at that sterling silver dial – the guilloche isn't just decoration, it's hypnotic, drawing you into the detailed sub-dials and the charming moon phase display peeking out. It's a watch that tells time, tracks elapsed moments with its chronograph, points to the date, and follows the lunar cycle. The thermally blued Breguet hands sweep across this intricate landscape, driven by the reliable Caliber C. 755 automatic movement humming away inside. It feels substantial, traditional, yet full of intricate details demanding appreciation. It’s like wearing a tiny, perfectly engineered orrery on your wrist, coupled with the practicality of a stopwatch, all finished with the supple embrace of hand-sewn alligator leather. It doesn't just sit there; it performs.

DescriptionThe Chronoswiss Lunar Chronograph, reference CH-7541LR, features a case constructed from 18-karat red gold, comprising 38 individual parts. Its dimensions are specified as 41 mm in diameter and 14.8 mm in height, accommodating a strap width of 21 mm. The case surface treatment incorporates both polished and satin-finished areas. A distinctive polished screw-down bezel with side knurling and a full thread secures the front crystal. The case back is a screw-down type, exhibiting a satin finish and incorporating a sapphire crystal window for movement observation. This model provides water resistance rated at 3 bar, equivalent to approximately 30 meters, rendering it suitable for incidental water exposure but not submersion. Attachment to the wrist is facilitated by a hand-sewn Louisiana alligator leather strap, which can be secured with either a pin buckle or a folding clasp, depending on the specific configuration.

Powering the timepiece is the Caliber C. 755, an automatic mechanical movement operating at a frequency of 4 Hz, or 28,800 alternations per hour (A/h). This movement contains 25 jewels and offers a power reserve of approximately 46 hours when fully wound. Finishing details within the movement include a polished pallet lever, escape wheel, and screws, while the bridges and plates are decorated with perlage. The rotor responsible for automatic winding is skeletonized, rhodium-plated, features a Côtes de Genève pattern, and operates on a ball bearing system for efficiency. The dial itself is fabricated from solid sterling silver (925) and features an intricate guilloche pattern as a special characteristic. Time and chronograph functions are displayed via central hours and minutes, a small seconds subdial, a central chronograph seconds hand, a 30-minute counter, and a 12-hour counter. Additionally, the watch includes an analog date display and a moon phase indication. The hands are thermally blued for color and durability, following the "Breguet Losange" shape, with the minute hand being meticulously bent by hand to follow the dial curvature.
