Hi all,
I had my milsub for about 6 months now. One thing that used to happen before was that after setting the time and pushing the crown in, the second hand would jump a few seconds. Recently, it stopped doing that i.e. no jump after setting the time. What happened?

Also, sometimes I hear a pinging sound sometimes when I put the watch next to my ear. It doesn't happen if it was resting for a bit but once I wear it and move it around, I can hear "ting, ting" at the same time as the ticking sound. Is that a problem?

My last question is about hand winding. Can it be over-wound and how many turns are the max amount?

Thanks

I am not a watchmaker. But I believe that this has to do with the engaging of the indirect seconds hand after hacking. I wouldn't worry about it.

Some of my watches make a tick tick sound and some more of a ting ting sound. I wouldn't worry about it.

No, it can not be overwound. Automatic winding watches have a gear that disengages when fully wound. I don't fully hand wind my automatic watches. I just give them a few turns of the crown (or swirls to move the rotor), set the time/date, and strap it on!

Thanks

cheers,

Does it go really fast (gain several seconds in a few minutes) when it makes that 'ting, ting' sound?

To add to Gigfy's 'indirect seconds' answer: there are threads with ST16 pictures by lysanderxiii. They show how the 'hacking lever' in this watch is a brake on one of the intermediate wheels, instead of stopping the balance. So instead of keeping the whole train under tension when stopped, the part after the brake is free to build up some slack. I'm not sure though how that alone would make the second hand jump after releasing the brake, and why it would go away. Might have something to do with the ratio of available torque and dampening due to friction. But wouldn't less friction (as the watch wears in) make the train oscillate more? I hope some (or at least one) of the more experienced people will chime in.
