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!
