What should I look for?

If it’s new/unworn, it should be good to go. You’ll know if there’s a problem if it doesn’t keep time within a few seconds per day. Assuming it’s just been sitting and not been used for any length of time, it shouldn’t need service or lubrication anytime soon.

^^^ What they said. It should be issue free, if there is something amiss it will show up in the timekeeping. Just wind it and wear it and keep an eye on the rate. All should be ok.

As @Evitzee noted, use one of those sites.

Accurate time keeping and monitoring is based on consistency, don't expect a watch to give reliable results if you wear it for a day, leave it for two, wear it for an hour etc etc.

Wind it fully on "day one" and set time to one of the links, then maintain a routine of wake up, sh!t/shave/shower, get dressed, put your watch on, give it about ten or so manual winds and then go about your normal day.

Don't check the time until the end of a week! Then compare it to the time on whatever site you use.

I know.......it's an automatic, so it should be perfect, but it's still a mechanical movement subject to variations in the positions it's worn and rested at, and if the wear/rest cycle is not regular the timekeeping will fluctuate.

If you are active during the day you could probably forget the morning winding, but it wouldn't hurt.

Let's know how it goes.
