Wearing my Omega 19" L.O.C. ( C being one grade lower than the D.D.R. , still chronometer grade ) from 1916 , in a 47.7 mm case.
The dial is signed with the Omega name and logo and also the name A B Oscar Burman Umeå Skellefteå Robertsfors.
Serviced and regulated, it still puzzles me how it can be so accurate, running at 1-2s deviation a day.
So far, haven't seen a caliber decorated same as this one.
