Kind inquiry on IWC Pilot 3777

Hello all,

Just recently bought a pilot 3777 and loving the look of this piece.

Apologies if these questions have been asked before, but would like to confirm from the kind forum experts here the following:

(1) Is it advisable to manually wind the watch even if I leave it on a winder the whole time I don't use it? (i.e., I use it 3 or 4 times a week and leave it on the winder the rest of the week);

(2) Is there a danger to overwinding the watch and is it normal that there is no noticeable tightening of the crown even if I've manually wound it more than 40x clockwise rotations?

(3) The winder I use has 3 settings, namely: clockwise, counterclockwise and both. I use clockwise rotations for the 3777. Is this correct?

Thanks in advance all! Happy Holidays!

If you use it alternate days then when fully wound it will last from Monday night to Wednesday morning so if you are reasonably active it should be wound up if you do some walking with your hands out of your pockets.
On a winder it will wind up in both directions but considering above maybe it's not needed.
There should be no need to wind the watch and it is impossible to over wind the watch manually.
A winder incorrectly set and rotating all the time will cause premature and accelerated wear on 7 day auto movements so with that in mind I would try without using a winder as not sure of the accelerated wear a winder can cause on this movement.

Hello JNO, welcome and congratulations on your beautiful watch!
(1)It is not advisable to manually wind that watch if you do not need to. If you use a winder, then the watch should be fully wound. If it is running and is showing the correct time when you remove it from the winder then there is nothing more you need to do.
(2) There should be no noticible tightening as the watch becomes wound. This automatic movement has a clutch mechanism to prevent overwinding, so manually or automatically overwinding the watch is not really possible. However, winding a watch more than it needs to be wound will eventually cause some excess wear and tear. Again, as long as the watch is running and keeping good time, you shouldn't need to wind it any more.
(3) Clockwise is the correct setting for your winder with this movement. It only winds in one direction and you have it right!

Thank you very much UK Greg and Ben!

Greatly appreciate the insights.

Happy holidays to the IWC community.

Hi JNO,
From completely wound down, it will take 800 clockwise rotations(looking at dial) to fully wind your watch. Once wound, one hour rotating after every 5 hours static, or 2 X 2 hour winding periods in 24 hours will be ideal to keep it at optimal power. A simple timer on your plug will do the job perfectly.
