For sale is a vintage Omega gold filled Seamaster Quartz watch. The watch has a 34mm case with 19mm brown after market Omega strap purchased in October 2017.  The movement is marked: Omega Swiss 1345 Omega Swiss Seven 7 Jewels Unadjusted.  The serial number is 40792546 manufactured in 1979/80.  The inside of the case back is marked: 20 Micron 196.0126.

The Renata 329 battery was replaced in April 2018.  The movement keeps accurate time.  The time is set by pressing in the crown for 5 seconds, releasing, and then repress to start the sweep minutes. The hour is set by pulling the crown and rotating to the correct hour. Also has a day/date indicator on the dial.  I found it easier to calibrate the second hand with the installation of the battery.

I ship the watch USPS First Class with tracking in a generic black faux leather watch box.
