April 1964 Seiko 5 Sportsmatic Done !!!!!
Just finished the partial rebuild of a tatty gold plated Seiko 5 Sports. Serial number dates it to April 1964..
I battled for hours trying to successfully fit the 2 minute date wheel springs. Numerous hunting with a magnet after they pinged off in all directions (even working covered with clingfilm).
Now up and running at +8 secs/d face up.
The real killer is that, as a 6606 movement, there is no quickset for the day or date. Thank god for Youtube where there is a single video that explains the best way to set this up.
Not doing one of these again !!!

Disaster-- the end of the click has sheared.. Unleashed the mainspring. Completely stripped down--lost a tiny washer on the minute wheel(should work without it). Balance may also be a bit dodgy now. Manually made temporary click.. Now the movement no longer thinks it is a 18000 A/h movement, running at 25000 +, Found new click in Japan. Looks a bit terminal as during the strip down found red powder on a jewel (although it looks ok to the naked eye) Bit of a cluster ****.

New click spring obtained from japan. Stripped down again and still running fast. Got a demagnetiser on the way, lets hope that does the trick otherwise its scrap time.

Assuming it was magnetized previously, how could it have been exposed during teardown and reassembly?
