Cal 50.0




(c):Vultures78

ZENITH XL-TRONIC has movement cal. 50.0, an electronically controlled tuning fork movement based on ESA 9162. It has sweep second hand, date quick set and electrical hack feature. It is a 13''' movement with 12 jewels beating at 300 Hz.

This model has been produced in 1.000 pieces between 1975 and 1976.

This tuning fork watch has 20 µm gold plated case and stainless steel back case. Gold colored dial and hands. Date is placed between 4 and 5. It “humms” very nicely and keeps very good time. Tuning fork watches were sort of transition between mechanical and quartz watches and are not produced anymore. They are rare findings and very hard to service, as spare parts are not made anymore. This particular watch was given to someone for 15 years of loyal work at Unger factory in Norway.
