MITKA

Service: Certina DS calibre 25-36

P1040603 This lovely pre-turtle back DS needs a service. The case back is screwed on super tight! 
P1040604

The best way to deal with a tight case back is to glue a nut on it. When it dries I use a spanner to open it. After I dissolve the glue in methylated spirit.
