This one I haven’t worn for several years. For two reasons. Several years ago, it quit! I tried a new cell, to no avail. So it has sat in my vault until last week when I happened to look at it, to find it was running! This one is likely from the early to mid-1970s, before Omega was absorbed by Swatch. This one is a stepper motor quartz. It came my way when the husband of a friend whose watch it was, passed away. Nobody in the family wanted it, and she wanted to find a good home for it. So she gave it to me. The bracelet is too tight a fit on my large wrist, so I likely won’t wear it very often.
This watch was designed by Omega to require a bunch of button pushing to set it to time. In the hand set position, when you turn the crown, the hour hand only, moves. Turn the crown and the hour hand will advance until the correct DAY shows, then move the hour hand until the time is set about one hour slow. Press the crown in to the wearing position. The crown has a dimple (button) in the middle. Press and hold it for 5 seconds, then release it and immediately press it in, and hold it pressed in. The three hands will advance until the watch indicates the correct time, then immediately release the dimple. The hands stop at the correct time. Then, a button on the case edge at the 4:00 is repeatedly pressed and released until the correct date shows. I have heard that, back in the day, Omega had so many complaints from agents, dealers, and owners about the cumbersome setting procedures that they re-designed the system.
