I received my 14060M a little over a month ago. When I first received the watch, I was gaining 5 sec/day for about a week. I tried different resting positions at night in attempt to "self-regulate" the watch, but position didn't seem to affect my watch's timing.

After about two weeks, I decided that I'd set my watch a minute slow and set my watch again once it got to a minute fast. So I unscrewed the crown, gave it about 60 turns in the winding position and set the time. About a week and a half into it, I checked the time to see that it was fast by an average of 4.25 sec/day. Not bad...at this rate, I'd only have to wind/set my watch once a month. However, the past week, my watch has been gaining between 6 to 7 sec/day. I'm not sure if it's just my watch "breaking-in" but it's a little disappointing. I'll continue monitoring the watch; if it's consistently out of COSC spec, I'll have to get it regulated.

I do believe there is a breaking in period, but that should only last a couple of days. I'd bring it in to have it regulated...

It does take a bit for all the gears to mesh but definitely take it tour AD if you have concerns ! However its still within Spec !

It's been my experience that a Rolex will pick up an extra second or so after a few weeks/months of use..

My theory is that the watch is initially dragging on the oil that has not "smoothed" out onto all the working surfaces.. If the watch has been running for a while before you get it, it doesn't experience this trait...........

In any event, if it's off by 5 seconds I would have it regulated........... I don't care what COSC is..

I've also found that Rolex watches will tend to gain slightly after some wear. Wearing habits also have an effect.

In my experience positional variation is slight (if at all) with modern Rolex movements.

A simple regulation would take care of it.

Key thing is establishing consistency so I'd give it another couple months to settle. Don't be too disappointed in current performance because if its' consistent, it is thus very accurate, just a matter of slowing it down a touch.
