I bought a relatively inexpensive non running A7123 Divers style SQ Sports 100 in June.
The bezel didn't turn nor did the day and date wheels and the crown was stuck.
I have done a very basic rebuild and modification as a learning exercise.
Case = A7123 8380
Dial 8229 801LT (The original got badly scratched due to me).
Hands = From original movement
New movement = Miyota 1S02
Crown = Yellow Non Seiko (can't remember the spec)
Case gasket = FH3030BOA
Bracelet = original Z343
Bezel was gummed up with what I think was salt. (A little warm water and a thin knife then some WD40 got it turning again).
While asking questions and doing some trial and error work I have had a lot of fun working on this and learnt a lot about how to handle the various parts and which tools/materials I need to do this type of modification.
Once the house move is out of the way I hope to learn how to actually repair a movement but one step at a time.
Now to see if it keeps working and doesn't let the rain in (I'm not going to get it pressure tested as I don't dive and won't be selling it).
My thanks to everyone who has helped me get this far,
Bern
