Seiko 1982 ~ 7120-7123 Movement

i inherited this watch, it was my grandads and is stamped on the back, i quite like it but its broken (not 100% sure whats up with it, ive been looking for watches with similar movements to cannibalise)

its stamped British Aerospace on the back which is what BAE systems used to be called, my grandad worked for them since English Electric which then became British Aircraft Corporation (BAC) and then British Aerospace.

the battery is also vintage as it has "W Germany" on it (from before the berlin wall came down).

heres some pics
