Omega Seamaster Memomatic 166.072 Alarm watch Blue dial very complete and serviced!

Steel Omega Seamaster Memomatic Ref. 166.072 vintage wristwatch, circa 1969

A stainless steel automatic centre seconds alarm wristwatch with date and two-tone dial

The Memomatic ref.166.072 was introduced by Omega in 1969. With a massive stainless steel case, measuring 40mm in width (excluding the crown), the case is detailed with a combination of satin and polished finishes. The model uses the highly complex Omega calibre 980 movement. Unusually the movement has a single barrel that controls the power for both the time and alarm functions. This means that the automatic rotor will provide all the power required for the watch to operate. The majority of vintage alarm watches incorporated a separate manually wound barrel for the alarm. Another unusual feature are the twin central discs which allow the alarm time to be displayed in hours and minutes, rather than via a single pointer as is more commonly found in alarm watches by other watchmakers. The pusher by 2 o’clock controls the alarm settings and a recessed pusher at 3 o’clock provides quick date adjustment.
