Greetings all. I recently acquired a moderately old Benrus 3-Star Automatic wristwatch. It's a #7026 Series. I believe these are from the 60's - though I don't know much about them. On the back of the case it says "open through crystal". Which makes me think that the Crystal should be removed using a Crystal Lift - and the movement lifted out through the bezel. Of course, the stem (presumably two-piece) would have to be separated prior to - or during the operation. BUT -
