1966 Bulova Wrist Alarm waterproof, manual winding alarm movement cal. 11AERC, 34.2mm. case.
The watch is wound using the upper crown, it winds both the timekeeping mechanism and the alarm. The lower crown is used to set the alarm and will operate when the lower crown is pulled out.
Look closely at the dial, note the unique “kris” hands of the alarm, a Movado design hallmark. They almost never survive the passage of time, so to find a watch with them still in place is unusual.
Bulova is the most successful American watch manufacturer. Established in 1875 in New York by an immigrant named Joseph Bulova, it was acquired by the Loews Corporation in 1979 and then again by Citizen in 2008, but continues to operate independently from the same New York location.
Bulova’s most important achievement has been the Accutron watch in 1960, which were truly revolutionary, though the electronic tuning fork movement of the Accutron watch was obsolete 10 years later by the introduction of the quartz movement.
