Black anodised aluminium rotating bezel, high-domed acrylic glass: the roots of this exclusive special edition for the specialist watch magazine Chronos run deep into the traditional pilot chronographs of the 1960s.
What immediately catches the eye of any connoisseur is the clearly designed dial. Reverse panda is the name given to the striking contrast between the matt silk, black electroplated dial and silver counters, which are modelled on the iconic panda dials. With their light dials and black counters, the focus of these mid-last-century classics was entirely on improved readability.
The silver reverse panda counters for the stopwatch minutes and the sweep second hand on the 103 St C capture this clear readability in their reversed colours. The pilot’s bezel can also be used to read off stop times of up to one hour.
By reducing the number of counters to two horizontally arranged bicompax subdials, the result is a balanced dial design with an additional elaborate detail: finely grooved counters that have been hollowed out to make them recessed. The case itself is made of polished stainless steel with a satinised back.
The overall impression of a classic pilot chronograph, whose production we have limited to 100 pieces in tribute to its history, is perfected by the brown vintage-style cowhide strap with black decorative stitching.
