Roventa-Henex

European Watch Clock and Jewellery Fair 1989 BF 307
Roventa-Henex has now designed its own proprietary line of quartz chronograph movements, only 5.20mm thick. This water-resistant model with two-tone styling features the RH 50 movement, the most complete in the line : hours, minutes, centre seconds, circular date calendar with pointer, 60-second and 30-minute totalizers, choice of moon-phase or day-of-the-week indicator.
