I'm wondering if anyone has had experience with this kind of issue:

This Rolex was just serviced btw.

Basically, I set it to atomic clock. Within the first 2 or so hours it gains about 5 seconds, then over the subsequent 24 hours it may gain 1 second, although some days it doesn't gain anything and is +5 seconds at the 24 hour mark.

So what would cause it to speed up after it being set, and then hold consistently? Any ideas?

While on wrist different positions and even temperatures how much power reserve in mainspring all effect the running of the movement so always fully manual wind before testing.Please don't get to anal about your watch the only way to test is over 5 complete days.When the bare uncased movements are tested at the COSC the test takes 15 days.Movement is tested in several different positions and temperatures.And in the first 10 days of testing movement could vary by up to 10 seconds over a single 24 hour test and still pass said test which is the movement should perform to a AVERAGE of between -4 to+6 seconds over any 24 hour period.

Agree the key word is "average" observed whilst operating in normal use rather than a few quick readings over short span of time.

It makes most difference if one must depend upon accurate timekeeping while untethered from the world of atomic clocks and other electronic doodads. Otherwise it's just a quick adjustment once a week or so...

Peter is right on the money. Being a mechanical device (even of the finest materials and engineering) it is subject to temperature, gravity, etc. That's why these measurements are taken over time for certification. Only really wild swings that can make you late or early for dinner should concern you.
