I have just aquired a pin set watch.
It is a Cylindre movement so I am told and pin set.
I today wound it and set the time for the first time.I looked at it 7 hours later and the hands had not advance at all.
I reset the time and after 10 minutes the hands were still correct.
My question is
If the pin is stuck partially down would it cause this problem as when I reset the time the pin appears to be sticking further out than before.
The watch has supposedly been serviced before I got it.

i realise this is not a high grade watch
thanks in advance

Yes, pins can get sticky, and so can the mechanisms they operate. Maybe you have loosened it now that it has worked once. You can try pressing and releasing the pin a few times to see if it just needs its lubricant spread around. Good luck!

If you can wind, it the pin is not stuck. If moving the crown moves the hands the setting device is stuck, but the hands should move some. If the hands are not moving when you move the crown, the canon pinion is loose. This is a tubular pinion that goes over the center wheel. It is a friction fit it carries the minute hand and drives the gears that run the hour hand.

Several methods of securing the cannon pinion were used when pin set cylinders were in use so we need a good view of the movement to see the problem.

An update
The watch actually did run when I reset it again but stopped after about 20 minutes.I left the watch for an hour to prove it was stopping and not running slow
I then reset it and the same thing happened,it ran for a short while then stopped.
The strange thing is I could still hear the movement and the balance was running when I looked .Maybe the action of turning it over was enough to get the balance oscillating for a short while.
Anyway it is on its way back to the seller for repair or refund

Another question
when I first wound the watch I was surprised at the small number of turns to reach what I assume was full wound.Is this because the watch is small or a cylindre movement or a fault.
I am used to my 16s watches requiring maybe 20 plus turns, this watch was only approximately 8-10

no the hands moved when the pin was pressed and the winder worked when the pin was not pressed.I think the watch was just stopping and my original though that the hands had not moved was incorrect

Seems to be a loose cannon pinion. It is a simple friction fit on your watch. The motion work is probbaly dirty. The cannon pinion drives a larger gear which drives a second pinion which fits over the cannon pinion. Crud in these gears can stop teh hand motion and if the cannon pinion is loose enough the watch will continue to run.
