Chronoswiss Opus Chronograph Titanium

Chronoswiss introduced the Opus in 1995 as one of the first serially made skeletonised automatic chronographs, and this is the current version in a Grade 5 titanium case, 41 mm across and 14.8 mm thick, rated to 100 m. The dial is almost entirely open, so the layout reads straight off the C.741S movement, with its black galvanised bridges and a CVD-coated skeleton rotor: central chronograph seconds, a 30-minute counter at 12, a 12-hour counter at 6, small seconds at 9 and a date at 3. It runs at 28,800 vibrations an hour with 46 hours of reserve. There are two references, CH-7543T.1S-BL2 in blue and CH-7543T.1S-DGR in dark green. The strap closes on Chronoswiss's ChronoClasp, a steel folding clasp that adjusts by up to 7 mm while worn, so it is not a nickel-free watch.
