This massive 40x50mm. OMEGA MEMOMATIC from 1970 is as clean as you will ever find! The case and bracelet essentially look pristine, as does the original dial, hands, OMEGA crystal an winding crown. The automatic winding OMEGA movement was just cleaned and is accurate. The OMEGA MEMOMATIC was introduced in 1969 and is the only alarm watch that uses a single barrel to power both the alarm and timekeeping. The nice part about this alarm watch is the fact you can set the alarm TO THE MINUTE; making this a highly precise and useful tool. This is a prime example.
