Silver case The first hallmark from above is the Swiss Duck for 925 silver which checks with the 925 on the right
The next is the FFBA one (Fédération de Fabricants de Boîtes Argent (FFBA) (federation of silver case makers))
If I read the number correctly as 4 that would mean the case was made by LaCentrale in Bienne.
The Crown with half moon indicates IMHO that the Case/watch was imported in Germany since that is the German hallmark for silver.
The watch resembles the CK 805 depicted in AJTT page 124 which has a 26.5mm mvmt. (which was made by Tissot for Omega AJTT page 780)
What do the real experts say?
