If 40 turns of the crown equals a full wind, how much do I have to swing around my arm for a full wind?

In other words, how many swings of an arm equals one crown rotation?

And if a beer is 12 ounces, and an average gulp is about half an ounce, how many beers would I have to drink to fully wind my watch?

It's not how many swings of the arm, it is how many rotations of the rotor, however you accomplish that.

Typical Rolex movements, 650 turns per day will keep it in a static state.... no loss/no gain.

Since the mainspring is a 48 hour power reserve, it would take ~1300 turns of the rotor to put in a full 48 hr wind if you could do it without any loss due to the watch actually running.

Most folks don't even put in the daily 650 turns and their watch likely only has around 20 to 30 hours of power.

If you have been wearing it normally as you would for a couple of weeks, put it on the counter until it runs down and stops. This will tell you about what you put into it daily, a more valuable metric than how many times you have to wave your arme.

Do your own math.

20 minutes using a Shake Weight usually gets 'er done.

I wear my watch every day for about 16 hours. Relatively active for a desk job guy.

Every time I've taken it off and let die to test the power reserve it ran 70 hours give or take an hour.

So I think if you're not passed out sleeping in a chair all day, regular movement will keep if fully wound.

Every time you glance at it to read the time you rotate your wrist and wind the watch.
