Has jewel reliable Bulova movement. In the early s, with World War II threatening and American involvement in the conflict imminent, Bulova entered into a contract with the United States government to produce instruments that would aid the American war effort.

Many of these had little to do with timekeeping, including altimeters, variometers, telescopes for range-finding on artillery, and time fuses for explosives. As one of the few American watch companies, Bulova took its patriotic duty quite seriously: The company also devoted 25 percent of its advertising to the promotion of war bonds and stamps, a service for which it was awarded a distinguished service certificate by the Secretary of the Treasury Henry Morgenthau, Jr.

The following tables will help you date your vintage Bulova watch. Watches dated post have a 2 alpha-numeric date code on the outside backcase, whilst watches dated before usually contain a date code symbol on the inside movement (see below for examples).

We see that some older chronographs have separate serial numbers for the cases and movements; that some chronographs Caliber 12 models, for example have serial numbers on the cases, but not the movements; we are told that the serial numbers on various models were used by the case-makers, but not by Heuer, so that Heuer maintained no records tying the case serial numbers to production dates, models, etc. All this leads us to the oft-repeated conclusion that serial numbers on Heuer chronographs are not useful for the purpose of dating a particular watch or for confirming authenticity in the sense of the case and movement having been together, since they left the factory.

Heuer’s serial number situation becomes all the more frustrating for those who collect vintage Heuers, when we see the lovely Rolexes and Omegas with the dates inside the case-backs and tables of serial numbers, including the years of production ; model numbers are also marked on the cases. But let’s get back to the Heuers: Even though we have authentic Heuer chronographs with no meaningful serial numbers, and cases and movements with no reference numbers at all, I believe that we can derive some worthwhile information from the serial numbers on the movements of certain Heuer chronographs, specifically those from the ‘s and ‘s.

One of the great inventions in watch making in my humble opinion, and a great piece of technology. The watches are mainly mechanical. The electronic part is keeping the tuning fork swinging — all the rest is done mechanically. But for this post, I will only take it apart and have a look at some details, and put it back together at a later time. The electronic circuit for the tuning fork is on the left – only a transistor, a capacitor and a resistor. Battery on the right, the 2 coils to drive the tuning fork on the top with the ends of the tuning fork around the coils , and the mechanical part in the middle.

The left coil actually consists of 2 coils, but we will get there later Battery and wheel bridge removed One huge difference to a conventional mechanical watch is that the power flow through the wheel train is inverted. So there are minimal forces at work, and the movement probably will take centuries to wear out if properly maintained. When the crown is pushed in, the contact is pushed up against the contact and closes the circuit.

When the crown is pulled out, the circuit is interrupted. This allows to store the watch without running the battery down And here I encounter my first problem – the central tube that holds the cannon pinion has rust on the outside and quite a bit of dirt on it. This prevents the cannon pinion from turning, thus making only the second hand turn – the minute and hour hand won’t turn The cannon pinion under the microscope This is the index wheel under the microscope.
