Keeping it running

• On an average day an automatic gains roughly 4 hours of reserve per hour on the wrist, so about 15 hours of wear fills the IWC 82000. Desk days charge more slowly.
• Most automatics can also be wound by the crown. If yours has stopped, a few dozen turns gets it going before you put it on.
• Off the wrist it stops about 60 hours after it was last full.
• If it does stop, don't set the date between 9pm and 3am. Here's why.

Never let it stop
