Another vintage Omega Seamaster added to the collection:

This one's powered by the 1337 Quartz movement from the early 80's. 17 jewels, IAHH, and accurate to within 5 SPM when it was new. 2 o'clock pusher can manually advance the seconds hand by 1 second for each push, while holding it down hacks the watch until released. The minute hand is not adjustable from the crown (the crown only controls the hour hand).

35mm square, so should wear a bit larger on the wrist than circular ones. What do you all think of it? (Got perm. from seller to share photos)

Nice!

That’s rather nice,could happily wear that.
