• Upcoming updates
    Over the next couple of weeks we will be performing software updates on the forum. These will be completed in small steps as we upgrade individual software addons. You might occasionally see a maintenance message that will last a few minutes at most.

    If we anticipate an update will take more than a few minutes, we'll put up a notice with estimated time.

    Thank you!

Hi -
Pictured is the circuit from a bulova quartz movement... Does this look like something leaked from the quartz oscillator?
- thanks!

That is just locking glue . The round goldish cylinder is your Xtal and it just filled with clean air .
The small white circle with a brass nut in the middle is the timing trimmer capacitor can be adjusted to make small time corrections , Best left alone . as it is fragile

In the case of watches, it is the resonator. The quartz crystal version of Bulova's tuning fork.
Sorry to say you are splitting hairs .all 32.768hz are fork or C . And run though a 15 flip flop array to give a division of 30 .
Giving a final 1.09 hz that is calibrated by a disc capacitor. . Most users here don't understand or care about the exact make up or design of Xtals .
I use double oven xtals temp controled for calibration .
Best regards Raymond.
