This is not an easy problem. Bulova were very offhand about giving models exact names. You'll find a guide for going about finding out about it here: http://www.watchophilia.com/general-information/determining-the-model-name-of-a-watch/

I agree with Geo. Also there might be an o ring washer missing.

Beautiful watch! Depends of where you live, it could be cousinsUK.com or ofrei.com among many....just my main preferences, check out section with suppliers!

Here are some photos of the amplifier I just completed, built exactly according to the schematic and circuit board layout I posted earlier. I borrowed a trick from my electric R/C flying days, where electronic speed controls often used heatshrink tubing as an enclosure. Here the tubing just acts as a sub-enclosure to provide some strain relief: Here it is in the case: Vintage style labelling: Oh, by the way, I measured the exact current consumption to be 3.63mA. Adding a red LED and 470 Ohm resistor would increase this to 19.2mA, thus cutting battery life to less than 1/5 of what it would be without the LED.
