    Help - have I killed my Citizen EcoDrive?

    So, I was looking to fill a Citizen Eco Drive GMT with silicon oil. I got the case open and popped the stem out, but after re inserting the stem, the hands are still frozen and not moving. The hour hands, date and GMT hand can be set fine and the stem appears to be locked in place properly but the second hand is not moving. Is there something I'm missing or have I damaged the movement?

    I've tried resetting it by pulling the stem out to the time setting position for 30 sec but no luck. I should say this is both when filled with oil and when emptied.

    Picture for reference!

    Only one of my wild guesses but is there a chance that the oil could be acting as an insulator of some sort?

    Either too little torque from that movement to overcome the density of the oil or somehow it was not dielectric and it fried the internals. My guesses.

    Is this something that has been successfully attempted by others in the past? I'm not a watchmaker but it sounds like you might have damaged something.

    I know some folks over in f17 have experimented with filling their G-Shocks with oil. Bell & Ross used to sell an oil-filled quartz diver and Sinn still does today. I'd imagine the latter two are pretty modified in order to function while filled with oil.

    Increases the water resistance depth (due to the oil being less easily compressed than air), and makes the dial very readable under water at any angle.

    Maybe I'm just not very adventurous, but I'd stick with buying the Sinn UX. That way I know it's designed to be filled with oil and the person who did it knew what they were doing.

    In retrospect, using lavender massage oil may not have been the best idea
