Quick TakeStep into a world of horological depth with the Flying Grand Regulator CH-6723-BLBL. This isn't just a watch; it's a conversation piece built on layers – literally. The galvanic blue dial is a miniature theater, starting with a guilloche base that catches the light just so. Above it floats the minute track, clear and commanding. But the real stars are the raised, funnel-like subdials for hours and seconds, hovering like precision instruments. It's powered by the manually wound Caliber C.678, a robust engine ticking at 18,000 A/H, demanding that satisfying daily ritual of winding. Encased in sturdy 44mm steel with mixed finishes and that classic onion crown, it feels substantial. The rhodium-plated "Poire Stuart" hands sweep gracefully, the minute hand even bent by hand – a testament to true craft. Paired with hand-sewn Louisiana alligator leather, it’s a watch that respects tradition while showcasing innovative design, perfect for someone who appreciates the mechanics as much as the aesthetics.

DescriptionThe Chronoswiss Flying Grand Regulator, reference CH-6723-BLBL, is housed within a stainless steel case measuring 44 mm in diameter and 12.48 mm in height. This case incorporates a combination of finishes, featuring partly polished surfaces alongside areas with a vertical satin finish. A distinctive onion-style crown is integrated into the case design. Securing the front is a polished screw-down bezel, characterized by a full thread and side knurling, which holds a curved, non-reflecting sapphire crystal. The case back is also of the screw-down variety, presenting a satin finish and equipped with a sapphire crystal insert, allowing observation of the internal mechanism. Water resistance is rated at 3 bar, equivalent to approximately 30 meters, offering protection against minor water exposure. The lug configuration accommodates a band width of 22 mm. The total assembly comprises 21 distinct parts contributing to the case construction.

Powering the time display functions is the Caliber C.678, a manual winding movement. This mechanism operates at a frequency of 2.5 Hz, corresponding to 18,000 alternations per hour (A/H). When fully wound, the movement provides a power reserve of approximately 46 hours. It is constructed using 17 jewels to minimize friction at critical points. The finishing applied to the movement components includes polished pallet, pallet-wheel, and screws. The main plate is rhodium-plated and exhibits circular graining (perlage). Similarly, the bridges are adorned with circular graining. A notable detail is the use of thermally blued screws, adding a visual contrast and traditional watchmaking touch. The movement's architecture facilitates a regulator display, separating the hour, minute, and second indications for enhanced legibility and precision time-reading, a hallmark of historical regulator clocks adapted for the wrist. The display configuration places the hours off-centre at the 12 o'clock position, utilizes a central hand for the minutes, and positions the small seconds display at 6 o'clock.
