    I don't know specifically about this clock but most 
clocks don't have spacers between the hands, rather the 
stems clamp the hand to the shaft. The root of the stem is a 
split spring which grips the shaft. If part of the split 
section had not broken off you can compress it a little with 
small pliers or tweezers and push it onto the shaft to the 
depth is should go. Some stems have a collar around the hand 
to aid in spacing. Make sure the hand is straight so it 
won't catch on another hand. You may be able to rescue this 
clock.
    Something else. I've found some clock motors have 
powdered iron cores or perhaps they are the magnets. They 
can begin to crumble and particles get into the motor. I've 
been able to get them out with sticky tape and toothpicks 
and the motor ran fine. I've had to do this to a couple of 
darkroom timers.
