Setting time and date in IWC Aquatimer - IWC Aquatimer Date Automatic Ss #354807 Watch for Men

Sounds like a problem with the hair spring inside, it will need a watch maker to replace or repair it.

mcdevito75 here, Shop NBC deals with IWC watches and they just might know, here is shop NBC info, 800-474-6762 Hope they can help.

mcdevito75 here, Depending on how new your IWC watch is, without running at all can be bad in the way that the oil in the movement can settle and more or less drain off the moveing parts, and without the oil distributed thru out the movement, your watch could run a bit fast. Re--starting your watch as you"ve done will help, re-distribute the oil, in the mean time switch your watches position on your wrist every couple of hours, crystal on top of wrist, then 2--3 hours later crystal turnned under the wrist, it may take a day or two for the condition to correct itself, if I'm right. Hopefully you have a warrantee with IWC on your watch. Hope this helps.

Try calling 310 734 0520. They should have what you need. You might not like the price though.

if its fitted with a screw down crown you need unscrew it anti clock, then pull crown out to first position and turn in either direction it should change one of the functions then pull it out to the second position and turn crown to set the other functionr remember to push crown back and screw back to case side its spring loaded on some model of AQ some models you need to pull crown in and out to change date then spin hands with crown to change day. IWC have a good website.

You have to send your watch. IWC do not supply any watch parts to private watch owners. Rate me, plz.

Obviously, you need a good shop to put it on so that it will stay on. You may not be able to tighten it sufficiently yourself. The case back may need to be taken off so that the stem can be held while the crown is tightened. Some times a little "locktite" on the threads maybe necessy
