Quick TakeTalk about a watch that refuses to blend in! The Flying Grand Regulator CH-6725-YEBK is pure wrist-bound drama. That vibrant yellow dial practically leaps out from the stealthy black DLC case – it's like sunshine piercing through a storm cloud. The multi-level dial isn't just for show; it creates this incredible architectural depth, drawing your eye into the separate time displays like little stages. The classic regulator layout, with minutes taking center stage, feels both technically satisfying and visually balanced against the off-center hours and seconds popping out from their guilloche-patterned funnels. Winding the C.678 manually connects you directly to its mechanical heartbeat, a slower, traditional 18,000 A/H rhythm. Strapped on with that rugged Hornback croc leather, secured by a practical folding clasp, it’s a statement piece that backs up its bold looks with genuine horological craft and the exclusivity of being one of only thirty made. It’s technical, tactile, and unapologetically loud.

DescriptionThe CH-6725-YEBK incorporates a case constructed from stainless steel treated with a Diamond-Like Carbon (DLC) coating, measuring 44mm in diameter and 12.48mm in height. Component assembly totals 21 individual parts. Finishing techniques applied to the case include partial polishing juxtaposed with vertical satin brushing. An onion-style crown facilitates winding and time-setting operations. The bezel features a polished finish, incorporates a full thread design for secure attachment via screwing down, and exhibits side knurling; it houses a curved sapphire crystal treated with an anti-reflective coating. Securing the rear of the timepiece is a screw-down case back executed with a satin finish, incorporating a sapphire crystal display window. Lug spacing accommodates a strap width of 22mm. Water resistance is rated at 3 bar, equivalent to a depth of 30 meters, providing protection against incidental water contact.

Powering this limited edition regulator is the manual winding Caliber C.678 movement, comprising 17 jewels and operating at a frequency of 2.5 Hz (18,000 A/H). It provides a power reserve of approximately 46 hours when fully wound. Movement finishing includes polished pallets, pallet-wheels, and screws, while the main plate is rhodium-plated and decorated with circular graining (perlage), and the bridges also feature circular graining. The dial architecture is notably complex, constructed on multiple levels. The base layer presents a guilloche pattern. Raised above this is a middle galvanic black level featuring printed indications. Funnel-like structures elevate the off-center hour display (positioned at 12:00) and the small seconds display (at 6:00). A top level, also galvanic black and secured by screwed foundation blocks, carries the scale for the central minute display. Time indication utilizes "Poire Stuart" shaped hands, which are lacquered and curved; the minute hand undergoes a hand-bending process. Production of this reference is restricted to 30 units.
