Patek Philippe

On an auction I recently purchased my Calatrava WG, Ref #3590, automatic caliber 28-255.
I have just got it back from Patek in Geneva after a service and restoration.
It's a beuty, I promise!
I have no spec. on this watch so I really don't know how many turns it should be wounded after
lying still and has stopped.
I have no winder yet, so I have been asking around about this and I got different answer every time.
People says 15, 16, 17 or 18 turns.
I have tried all and it seems to be to few turns and still not happy with the power reserve.
Does anyone know how many turns you should wound this watch?

Just about 10 turns should get it going.

Then once it is going wear it .. The watch will get wound by your motion and the power reserve will go up during the day nicely to the maximum.

The caliber 28-255 requires 650 turns per day in both directions .. Clockwise and Anti-Clockwise. This will happen easily on your wrist during a normal day.

Thanks for the answer!
I have tried 15-18 turns and used it during the day.
Every night I take my watch off and after 3 or 4 days
the watch has stopped during the night.
I thought maybe 15-18 was to few turns but
I maybe have to send it back to Patek again for
checking.
That will be another 10 wks of waiting!

If you have been wearing your watch for a few days it should never ever stop.

Whilst you wear your watch and move about it should wind to maximum and them run for more than 24 hours. That way if you wear your watch every day it will never stop.

If it stops after 3 or 4 days it is wrong somewhere.

It is possible, although unlikely, that you are simply not moving around enough to wind the watch fully while you wear it. You might try experimenting by wearing it or moving it around quite a bit (think in terms of causing the rotor to revolve about 1500 times, which should fully wind the watch), then put it down and see how long a power reserve it has. If it has an appropriate power reserve (probably 38 - 42 hours for that movement in vintage condition), then the problem is that you need to move around more.

Yes, I work in an office and sit by the desk almost the whole day, but of course I do move a round during the day.
I will try your suggestion!

Thanks a lot!

... bought one myself about 3 weeks ago - it´s 36mm diameter and have a second one "oversize" with a diameter of 37mm and the cal240 - those watches are amazing - so simple and elegant - my absolute grail watches.
