Rolex A 7750 Daytone secs @ 9 keeps stopping

Hi All,

 

I have the aforementioned watch, that had been running fine for about 6 months but now keeps on stopping. When it stops, the second hand (at the 9 o'clock position) is always showing "10 seconds past"  I have checked and the hand is not sticking or making contact with the dial or anything on the dial face.

A quick tap starts it working again but before too long it stops.

I do not ever use the chronograph features ;-)

 

What I have checked...

 

Reversing wheel and click

Main click

Oscillating pinion

Clutch

Balance and escapement

 

Any ides would be most welcome and appreciated!

 

Thank you 

 

Phil

Indeed, servicing the watch is what I wish to do.  

I recently rebuilt the watch and feel confident that there are no broken parts, and the watch was also lubricated at that time. Strange that the watch always stops with the second hand at exactly the same point, yet there is no contact between the second hand an any part of the dial or other hands.
