Quick TakeThis isn't just a watch; it's a statement piece that rewrites how you read time, putting the crucial minutes front and center where they belong. The Chronoswiss Regulator Manufacture CH-1243.1 throws the conventional dial layout out the window, opting for that iconic, functional separation of hours, minutes, and seconds. It’s a nod to historical precision instruments, brought to life with modern Swiss manufacturing. The dial is a masterpiece in itself – solid sterling silver transformed by mesmerizing guilloche patterns, catching light in ways flat dials only dream of. Then you have those gorgeous, thermally blued "Poire Stuart" hands sweeping across it, the central minute hand even getting a special hand-bent curve. Beneath this visual treat beats the heart of the operation, the in-house C. 122 automatic caliber, visible through the sapphire case back. It’s all wrapped up in a robust 40mm steel case with that signature knurled bezel, mixing polished and brushed surfaces like a pro. It's a conversation starter, a piece of horological art, and a delightfully unconventional way to keep track of your day.

DescriptionThe CH-1243.1 model employs a meticulously constructed case fabricated from stainless steel, presenting specific dimensions of 40 millimeters in diameter and 11 millimeters in height. This housing is composed of 19 individual parts, ensuring structural integrity and detailed finishing. Attention to surface treatment is evident, incorporating both polished and satin-finished sections across the case body. A key element is the polished screw-down bezel, notable for its side knurling and full threading, contributing to both aesthetic appeal and functional assembly. Complementing the bezel, the case back is also a screw-down type, featuring a satin finish and incorporating a sapphire crystal window for observation of the internal mechanism. This construction methodology supports a water resistance rating of 3 bar, equivalent to approximately 30 meters, suitable for incidental exposure to moisture. The lug spacing is standardized at 20 millimeters, accommodating the specified strap configuration.

Powering the timekeeping functions is the Manufacture Caliber C. 122, an automatic movement operating at a frequency of 3 Hz, which translates to 21,600 alternations per hour (A/h). This movement integrates 30 jewels to minimize friction and enhance longevity. When fully wound, the mechanism provides a power reserve of approximately 40 hours. The dial itself is crafted from solid sterling silver (designated 925) and features intricate guilloche work, adding significant visual depth and texture. Time indication follows the classic regulator layout: minutes are displayed centrally via a large hand, while hours are indicated on a sub-dial positioned at 12 o'clock, and running seconds are shown on a separate sub-dial at 6 o'clock. The hands are of the "Poire Stuart" shape, thermally blued for color and corrosion resistance, diamond-cut for precision, and possess a distinct curve, with the minute hand being carefully bent by hand to follow the dial's contour. The strap is made from calfskin, treated with an alligator embossing for a premium appearance, and secured by either a traditional pin buckle or an optional folding clasp.
