Function: Time (HR/MIN/SEC) , Alarm Some history of BULOVA and Wrist Alarm watch: The Bulova Corporation was founded in 1875 by a Czech immigrant named Joseph Bulova, at a small premises in Maiden Lane, New York City, USA. Little did anyone know at the time that this tiny fledgling enterprise was to grow into an empire that would irrevocably change the world of time and one day help put a man on the moon (Bulova Spaceview Accurtron). Fast forward to 1948, Bulova research scientists and engineers had continued to experiment in alternative, more accurate timekeeping technology. Since the days of the quartz clock with Bell Laboratories, Bulova engineers were convinced that a stable constant source of vibration would be the answer to a replacement for the mechanical spring and balance wheel of a conventional watch. The problem was how to make it small enough to fit into a wristwatch. The existing quartz clock was the size of a room and the ability to produce microelectronics, capable of reducing the high vibration speed of a quartz crystal to a regular pulse suitable for controlling a watch, was still many years away. In 1953, Bulova research scientist, Max Hetzel, working in the Bulova laboratory in Bienne, Switzerland, came up with the solution. Accurate to within two seconds a day, this first true revolution in the watch making industry since Christiaan Huygens' pendulum clock of 1656, didn't tick anymore, it hummed. A tiny battery caused a micro tuning fork to vibrate at exactly 360 cycles a second. The challenge was to bring this invention from the research laboratory to the production line as a commercially viable product, suitable for mass-production. While work progressed on Max Hetzel's humming watch, Bulova continued to recognize the new trends of the industry by introducing move versions of its popular self-winding watch. In 1953, Bulova introduced the 'Wrist-Alarm', an entirely new concept in wristwatches. THE BULOVA WRIST ALARM WATCH This Bulova wrist alarm watch in addition to displaying the time, the mechanical movement features a secondary manually-wound spring which, when wound and released operates an audible buzzer, alerting the wearer at a pre-set time. This buzzer not only makes noise, but physically vibrates the watch, noticeable both on the wrist or when placed on a hard surface - making the watch usable as an alarm clock as well ! Very rare collectible timepiece. While most collectors think of brands like Vulcain and Jager-LeCoultre when thinking of alarm watches, Bulova was also a major player, producing a number of wrist alarm variants starting in the late 1950’s. This particular example dates to 1968 and features Bulova’s in house alarm movement, the Cal. 11 AERC. With a 34mm case, beautifully aged dauphine hands, and a distinctive alarm hand, this Bulova brings the charm and engineering of a proper mechanical alarm to your wrist. How the Alarm works? Given the relatively complicated (pun intended) nature of this watch, a short primer is in order. This model has two crowns, but they share a common barrel. To wind the watch and the alarm, wind the upper crown at 2 o'clock. Note that winding is not possible with the alarm enabled. To set the time, pull the upper crown and set the time as usual. To set the alarm, wind the bottom crown at 4 o'oclock- please note that it can only be set in reverse. To enable the alarm, pull the bottom crown out. To disable it, leave it pushed in.
