This is an almost perfect example of the Omega MG 1166 timer. Comes with its original Omega red box, which is also in almost perfect condition.
 
One revolution in 60 seconds, 30 minute totaliser. Push the crown once to start, again to stop and again to reset to zero.
 
Inside is the Omega 9000 movement. This is in fact the world-renowned Lemania Movement
 
You rarely see these times where both the box and watch are almost as new.
