This Gruen, today. A manual wind day/date. Not something often seen. I wear it so seldom that I have to retrain myself as to getting the day and date correct, every time I wear it. At the date change, the date changes first, the day very quickly thereafter. The day can be backed up, the date can’t. Set it ahead until the date is correct, then back it up until the correct DAY shows. Then continue backing up until you reach the correct TIME. A pain in the derrière to set. But I’ve worn an auto wind watch without the date for a while, and that also is a pain.
