Came across this watchcase when I bought a watch lot from eBay. Seems NOS (as case is free from scratch, and backside is protected with adhesive tape).
Watch case has a push pin at 8'oclock, and case back is marked ANTIMAGNETIC-INCABLOC-WATERPROTECTED Automatic 9008 88. Tried googling the mark
but came out with nothing. I want to ask what is the purpose of the push pin on the 8oclock area, and what kind of movement I can use for it. Watch case is 35mm in dia, inside dia at 30mm.
Thanks in advance
