I am rebuilding a 1980s Seiko SQ100 Sport 6923 7069 (A) using a 7N33M movement.
This is to get the watch running and teach myself how to do it.
I have found the hands required are (Hr, Min, Sweep second) 110, 65,21 and the battery is a 371.
I have two questions I would appreciate some help on please.
The main supplier here in the UK offers two sets of hands which look suitable.
65/100 and 60/110 with a second hand which has the right diameter centre at 21mm but is slightly too long.
Any suggestions as to which set of hands I should go for, the 65/100 or 60/110 (or do I need to mix hands from both)?
I have also noticed on the bottom of the small compartment where the battery cell will go there is a metal tab which has a thin plastic covering strip on it. Will I need to remove the strip before I fit the battery?
My apologies if these are VERY basic questions. I'm leaning fast!
Thanks for looking,
Bern
