This thick quality spacer was for me the biggest positive surprise when doing this disassembly. I had never seen such a nice fitting spacer, normally most spacers almost fall out when you have unscrewed the case back. This one sits very firmly and secures the movement nicely. The three slots have to be used to "wiggle" the spacer out by using all three slots alternatively. A really nice solution to store an ETA 2824 in a 40 mm case.
