Swiss luxury watch maker, Dubey & Schaldenbrand presents new automatic watch model Gran’Chrono Astro at Basel world 2009. This imposing model adds a triple calendar (day of the week, day of the month, month) and moon phase function to the previous model, the Gran’Chrono. These new complications are housed in the same curved tonneau case. Shaped push-pieces have been specially designed to improve the watch’s aesthetics and guarantee optimal comfort.
It took over 90 operations and 16 months to produce the final prototype of the double curvature of the case, while the exclusive guilloché dial required the same meticulous attention, a total of 85 different stages.
