At Baselworld 2014, Chronoswiss released, for the first time ever, a skeletonized version of its sporty Chronoswiss Timemaster Chronograph, which allows wearers an unencumbered view of the watch’s filigreed and decorated automatic movement and offers two different dials, both surrounded by robust, DLC-coated bezels.
Both versions of the Chronoswiss Timemaster Chronograph Skeleton have stainless steel cases (44 mm in diameter and 15.3 mm thick) with bezels made of polished, black DLC (“diamond-like carbon”), an extremely hard and scratch-resistant material. The bezel features a 5-minutes scale with inlays made of Super-LumiNova. The 52-part case has a nonreflective sapphire crystal, a threaded, embossed screw-down caseback, screw-in lugs with Chronoswiss’s patented Autobloc system, and a vintage-style “onion” crown, a hallmark of the Chronoswiss brand. The case is water-resistant to 100 meters. The two dial variations are galvanic black and galvanic silver. The former (Ref. 9043 SB bk) uses white Super-LumiNova for its highlights, including the bezel numerals, hour indices, and hands; the silver-dial version (Ref. 9043 SB si) uses a turquoise-colored Super-LumiNova for these elements. Both dials have the date display on a subdial at 3 o’clock, 30-minute chronograph counter subdial at 12 o’clock, 12-hour chronograph counter subdial at 6 o’clock, and small seconds subdial at 9 o’clock. The watch comes on a black rubber strap with a folding clasp.
The main attraction, of course, is the skeletonized chronograph movement, Caliber C.741 S, which is 30 mm in diameter and 7.9 mm thick. It has 25 jewels, a Glucydur balance with Nivarox balance spring, Incabloc shock protection, a frequency of 28,800 vph, and a power reserve of 46 hours. Its numerous decorative elements include a skeletonized rotor with côtes de Genève, a polished pallet lever and escape wheel, bridges and baseplate with perlage, and blackened parts.
