Lol 41mm auto SMP's on the bay for less than $1000.00??? How am I missing these? I've seen some but they are in terrible condition and not the blue bezel models.
My ETA SMP now has a gen dial, gen bezel, gen dw, gen hands and gen crown and all it cost me was $600.00 installed. If you spend the time to shop for parts, it's actually reasonable.
A gen quartz in satisfactory condition will still run you minimum $900.00 delivered. Unless you go with a mid size...and even those are more than $800.00...
Anyone looking to Franken for starters will need to start with an ETA movement. Your 21j wont take gen parts.
