1972 Bulova Accuquarts Day Date. Asymmetric shaped case. 2242 Bulova UAS movement. This a another is another that had been discarded as broken. When I acquired this watch the battery retaining bar was missing. A fellow Bulova collector in a Facebook group was kind enough to offer me one of his spares for free. Once installed with a new battery it took running. Humming like a champ. As you can see, the movement has had a rough time or two. Looks like severe battery corrosion but still has not stopped this guy from keeping almost perfect time. The first month I had it operating it picked up 12 seconds. There is still some work to be done. The wind is tough and the day and date wheel do not advance. It has an appointment with my watchmaker and hopefully will be good as new soon. I love the Asymmetric shape watches. Its just a great piece to look at. The shape, the dial finish is a sort of a two tone metallic, the diamond and logo at the 9.
I have so far been unable to locate any adverts with this case style.
The Bulova AccuQuartz movements utilized both Quartz and tuning fork technology. Basically, production costs were high, and the two systems together were redundant, so they became Quartz movements. The idea was that the Quartz crystal could regulate the tuning fork more accurately, but this was unnecessary. What followed would be the stepper-motor Quartzes followed by ones with the modern rotor and stator.
Also, I believe my watch may be falling in line with the Line Book image posted in this thread. The linebook date is shown as '73. My case back is marked N2 but after digging through some corrosion I have found an N3 on the movement. Its an N3 that they used an N2 movement for, or...I have the wrong case back. Has anyone seen this case on a confirmed N2 of any model ? was it even in existence in '72 ?
I can recognize the movement as clearly an Accutron movement. The caliber 224 series is the Accuquartz movement; 2242 is the version with day and date. They had the rectangular block at left center for the circuitry, as opposed to the discrete soldered components visiblein the 214 and 218 movements. The row of six screw holes at the far left is for adjustment/regulation, ranging from coarse (bottom position) to extremely fine adjustment, in the topmost position. Adding a screw to a hole slows the watch down.
