I recently purchased this watch in a watch lot and I know nothing about alarm wristwatches. I am able to set the time by pulling out the stem located at 4 o'clock but I must maintain pull on the crown while adjusting the time. Is that normal for this type of watch? I've played around a bit with the upper stem. It seems the alarm time is set by pulling the stem out. The alarm time hand adjusts only counter clockwise. When I twist the upper crown while the stem is engaged, it feels like I am winding a watch. Is that how the alarm is wound up like an old time alarm clock? Does anyone have any additional info on the movement? Any info is appreciated.
