This watch is not defective and is designed with only one hand.
The original M24 watch is a one-handed Japanese quartz movement that lets you read the time between hours in 15, 30 and 45 minute hand positions. The time between hours is in increments of 15 minutes. If the hand is a quarter of the way between 12 and 1, the time is 12:15. If the hand is halfway between 12 and 1, the time is 12:30.
The watch is not defective and is designed with only one hand.
The M24 II watch features two hands.
