CERTINA DS Quartz, ca. 1990
Opening CERTINA snap-on Backs
Is not that easy. CERTINA snap-on backs are different then anything snap-on I had seen so far. There is a small gap between the edge of the snap-on back that goes around the case back, rather then an opening groove at a specific location.
Please also note the Scotch Tape to protect the case while working with the very nifty Bergeon case back opener.
