Odd behavior...14060

[stil]

Hi All,

I have a 20 year old 14060 that was serviced within the last 18 months. It's been running like a beast until last night. I took it off to wind it up and reset the time. I went through my normal procedure to unwind the crown, wind the watch, pulled it out further to stop the seconds, set the time, pushed in crown and screwed it down. Put the watch back on and didn't think about it again. The time was 10:12PM.

This morning I put the watch only to notice that the time was still 10:12 and about 15 seconds. So I went through the same process again and it's been running fine since.

Would you recommend to have a watchmaker take a look at the internals to make sure everything is OK? Does this sound like acceptable behavior?
