My wife's 2 month old Datejust is gaining about 10 seconds per day. I have not done a scientific time test other that set the exact time to the atomic clock on Oct. 20th, today it's 50 seconds fast. It's stored on it's side crown up. Too new to regulate it? I heard it may take a few months before it settles down?? What's the process to regulate? How long does it normally take?

Try observing it for a week, and note the daily variance. Try storing it dial up instead of crown up too. If it's still running outside COSC parameters, then you can send it to Rolex USA and have them regulate it. John

At this point there is nothing to worry about. New Rolex watches often run fast or slow and need about six months to 'break-in' before they start keeping steady time (i.e., it may be fast or slow, but it will always be the same amount of time fast or slow).
I wouldn't worry for a few months. If it's still that fast after six or eight months, have it regulated by an authorized dealer. As for storing it in a certain position, it really doesn't make much more than a second or two a week.
Keep in mind, ladies-sized Rolex watches don't have as long a power reserve as the full-sized ones. The mass of the rotor can't fully wind the main spring through normal wear. This won't affect accuracy, however, but it may mean that if it's not being worn every day, your wife may want to manually wind it to avoid having to reset it.
Regulating a Rolex shouldn't take a watchmaker more than an hour or two max. However, the time required for the watch to make it from the front counter to the watchmaker's work bench is dependant upon their backlog, (and your proximity to an authorized watchmaker, remember it's under warranty, so why screw around).
All that said, 10 seconds a day isn't too far out of the COSC standards, so I'd wait a bit and monitor it for a week at a time.
Congrats on the watch, btw.

My Dweller is actually running about +8 per day (odd because for the first three weeks I owned it, it was running -2). I'm a bit concerned at this point, but I'm going to hold off sending it to Rolex until after the holidays. John

from people leaving it in different position during rest will effect the timing performance! Something to do with the balance of the movement in different positions!
