Who's had their new watch regulated?

[delldeaton]

I'm still less than a week in on a new Rolex, but figure it will end up losing about half-a-second a day. Unfortunately, I'm one of those types who'd rather have it gain 3 seconds a day than have that.

So I was wondering if anyone else had had a relatively new watch regulated so soon?

Beyond that, how long does it take (will he need to keep it a while)? Can the AD do it? Is it something they'll likely get right the first time, or will I be back again w/ it? What should I be concerned about (eg, pressure testing the watch after it's re-sealed)?
