I never could never get to throwing away my old and broken (automatic movement) and beloved Seiko 7009-3140. Had no problems doing this with my much costlier Eternamat
which 1) claimed to be a chronometer, which it wasn't, and 2) finally gave up the ghost, with a potential of costing a fortune for the repair.
After deciding to 'go quartz', I have purchased a Hattori VX43E movement, and wish to fit it into the remains of my Seiko .
Questions :
Where do the 2 gaskets A and B in the photo go ? Which way up ?
Is it necessar to vaseline the rim of the crystal before inserting, and also of the tiny gasket in the screw back ?
