Quick TakeAlright, let's talk about this blue beauty, the Delphis Sapphire. It's not just telling time; it's putting on a show! Forget a boring hour hand creeping around – BAM! – the hour jumps instantly in its window at twelve. Then you've got the minute hand doing this cool retrograde dance across the top half, snapping back like it just remembered it left the stove on. Down at six, a little seconds subdial keeps the rhythm steady. That sapphire blue dial isn't just flat paint; it's got this deep, hand-worked guilloche texture that catches light like crazy, almost hypnotic. The whole thing sits in a solid 42mm steel case that feels purposeful, not delicate, backed up by 100m water resistance so a splash won't faze it. Even the crown's got that classic onion shape, a little vintage nod. Strapped on a rubber band with a secure folding clasp, it’s ready for action, but the sheer artistry of that dial and the mechanical ballet happening beneath say it's way more than just a tool watch. It's a conversation starter limited to just 50 pieces, making it a rare bird indeed.

DescriptionThis particular Chronoswiss model, reference CH-1423.1-BKBL1, known as the Delphis Sapphire, is constructed with a case made from stainless steel. The case dimensions are specified as 42 millimeters in diameter and 14.5 millimeters in height, providing substantial wrist presence. It accommodates a band width of 22 millimeters. The case finishing incorporates both polished surfaces and areas with a vertical satin finish, creating visual contrast. A notable design element is the inclusion of an onion-style crown. The case back is a screw-down type, featuring a satin finish and incorporating a sapphire crystal for viewing the movement within. Water resistance is rated at 10 bar, equivalent to 100 meters, ensuring suitability for various aquatic activities short of deep-sea diving. Securing the front of the watch is a polished screw-down bezel, characterized by a full thread design and side knurling for grip. Protecting the dial is a curved sapphire crystal, treated with a double anti-reflective coating to minimize glare and enhance legibility under different lighting conditions.

Powering the Delphis Sapphire is the Manufacture Caliber C.6004, an automatic movement. This self-winding mechanism operates at a frequency of 4 Hz, which translates to 28,800 alternations per hour (A/h), contributing to the smooth sweep of the seconds hand and overall timekeeping accuracy. The movement provides a power reserve of approximately 55 hours when fully wound. Its construction incorporates 37 jewels to reduce friction at critical points, enhancing longevity and efficiency. The finishing details of the movement are meticulous, including a polished pallet lever, escape wheel, and screws. Furthermore, the bridges and plates are adorned with perlage, a pattern of small, overlapping circles. The rotor, responsible for automatic winding, is skeletonised for visual interest and features a ruthenium coating. It is decorated with Côtes de Genève striping and utilizes a ball bearing system for efficient rotation. The dial itself presents a complex, three-dimensional construction and features a curved surface finished with hand-applied guilloché in a distinct sapphire blue color. Time indication is achieved through a digital jumping hour display positioned at 12 o'clock, a central retrograde minute hand that sweeps across an arc and snaps back to zero, and a conventional analogue small seconds display located at the 6 o'clock position. The hands are rhodium-plated, feature a skeletonised design, and are crafted in the 'Viking' shape. Completing the ensemble is a rubber strap paired with a folding clasp for secure fastening. This model is designated as a special limited edition, with production restricted to only 50 pieces worldwide.
