I bought a 2252.50 (the mid-size version) this past June and it took about 3 months to settle down. It started out about 1.5 seconds/day slow and gradually sped up. During that time I pretty much wore it the whole time, even when sleeping. I generally wouldn't wind it unless I had a particularly sedentary Sunday.

It now gains about a second a week. I'm really happy with it. I note that if I don't wear it and set it down dial down, it will gain a second in a day, and lose a second if set down dial up.

-4 sec/day out of the box might bother me but I'd track it every day just for the sake of accurate data. I note that mine will still lose or gain 4 seconds within a week's time depending on how often I wear it, how I set it down, and how active my left arm was during the week.

I'd talk to the dealer and tell him that you are tracking the accuracy of the watch and if he won't let you return it after a couple of months (for a swap) you'll return it now.

: Just bought a SMP 2254.50 w/ 1120 movement on
: Tuesday (around lunch time). I realize that
: there is a "settling in" period
: for automatic chronometers, but I have it on
: good authority that I shouldn't wait on
: this. I'd like opinions from any of you all
: as well.

: Rough checks against the USNO atomic clock
: showed a 1- to 2-second loss by the end of
: the first evening. Before putting the watch
: "in service," I gave it a full
: wind, and I have worn(and continue to wear)
: it round the clock, including to sleep.
: Thursday morning, down by a clear 3 seconds,
: and by the end of that 24-hour period, it
: had lost over 4 seconds.

: Yesterday evening, I gave it a full-charge
: wind, altho the audible clutch-slip
: indicated that it was already fully wound.
: Now that things really had my attention, I
: made as sure as my eyes, fingers and ears
: could be that it was dead-on w/ the USNO
: clock. Now 12 hours later, -2 seconds or so.

: I'm reminded that COSC standard is -4 to +6
: seconds, and that Omega says its standard is
: -1 to +6 seconds. As I have purchased an
: OMEGA watch, and not something else, I think
: it is reasonable to demand the OMEGA
: precision specification.

: The AD says to give it a week to settle in. The
: AD also insisted the 2254.50 has a 60-click
: bezel, just like my 2531.80 does; I won't
: insult those of you who own these 2 great
: watches by noting what you will notice
: simply by LISTENING as you turn your bezels!

: An Omega expert who I trust very highly says
: that while a chronometer will, indeed,
: settle in over a week and even a couple of
: months, it should *NEVER* be out of COSC
: specifications. (I'm extrapolating from that
: to think the same holds true for Omega
: specifications as well.) So I am inclined to
: force the issue, either exchanging the watch
: for a new one -- and beginning serious time
: checks on that one right away! -- or taking
: a full refund.

: Opinions? Is 48 hours enough to know there's a
: problem? Would you wait, for any reason?

: Thanks!
