So embarrassed! Changed the battery yesterday. Obviously the hour changes from the crown, advance to change the date. Trying to adjust the minute hand, thought it was the little inset button in the case side but I can’t seem to get it to do anything. Help an old man would you?
It might have helped had you shown the 3 side of the case. Some Omegas with the tiny button on the side of the case, involve pushing the button IN, and HOLDING it in for 5 seconds. Then release and immediately press again, holding it pressed it. With many Omegas of the era, the hands with revolve at about 20 rpm of the minute hand. When you get close to the right time, release the button, then immediately press and release as the minute hand moves ahead, one minute per press. Hopefully, these instructions work for your watch.
Thanks chaps but none of the above instructions work for me. Maybe it has a fault. Edit. Sorted, turns out the crown pops out another setting for the minute hand, duh.
