Pretty proud of myself today. Yesterday I rebuilt the 2824-2 using the ETA manual (after failing with the Selitta manual), and today I did a teardown and rebuild without having to use the manual for like 90-95% of the movement.
Having a calendar makes it quite a bit more complicated, especially in the keyless works area (for setting the date without having to move the time 24 hours for each day).
The parts in the bottom left portion of the container are for the calendar works and keyless works (and a couple parts for time setting). Quite a few extra parts to remember! I hope to be able to do it without the manual next time. I'll pay extra attention during disassembly.
Also I can't test the function of the watch yet until the new spring arrives tomorrow. That one tiny nose hair sized spring prevents everything from running!
In the meantime, I did a full service of the 6497-2 and it seemed huge in comparison! I can disassemble and reassemble that thing very quickly now, and have it running with good amplitude and timing.
