Junghans 623.05


The caliber 623.05 from Junghans, one of their last native movements, which is a rather simple one (only three time indications, no date and only fifteen jewels), was used by Diehl, the mother company of Junghans, in their watches.

Unlike on caliber 623.20, the main plate is flat. The main plate carries all gears, which makes servicing quite difficult. On the other hand, the anchor is beared in a Diafix shock protection system, while the balance runs in simple Ruby Neutro-Shock bearings.
