Hello folks,   I  bought an old Benrus ref. 1345 from the bay, item arrived today. It has a solid case back that denotes also for the opening of the watch through the crystal. As you can see from the posted photo, I have already removed the acrylic crystal and the outer ring with the minute indices. But now, how do I proceed to remove the movement? Is there a specific way to remove the stem from the dial side?     Thanks in advance   Evan
