No worries, that's very normal for a mechanical watch and is actually a very good amount of deviation. Mechanical movements are not as accurate as Quartz and even COSC chronometer standard watches (one of the highest certifications for mechanical watch accuracy) is something like +6/-4.

Just to be clear, the testing results you found were for a particular watch and those results won't be the same for every example of that watch (i.e., just because that particular watch was +1 at crown left doesn't mean yours will be). Every watch has its own quirks and variations and it even varies over the watch's lifetime and the seasons (no kidding). I've had stretches where my JLC is dead on over a month and other periods where it's +3-5 every day.

Crown left just means orienting the watch physically crown left, i.e. Upside down so the crown points left instead of right. Obviously on your wrist the watch will be in many different positions over the course of the day, there's no way to put it in one orientation.

When you sleep and take the watch off, it may be worth resting it in one position that makes it most accurate. Watches tend to be slightly faster dial up, i.e. Flat. Slightly slower crown up, i.e. On its side.

Experiment with it and have fun! Part of the enjoyment of the hobby is learning the quirks of your particular watch.

 

Thanks for the helpful response. I will try crown up tonight and see what it does tomorrow. It is a fun hobby and I am glad I am getting into it. I look forward to adding more to the collection!

 

Those are honestly all pretty good in terms of time keeping.

If you want accuracy, buy a quartz chrono....these are within 0.5sec per day...day after day after day...under $200.

Thanks for the suggestion, but if I wanted the quartz, I woulda bought a quartz.

Congratulations! That's great performance. Enjoy your new watch.

 

My Russian clock acts +/- 2 seconds a day. I wear it all the time and watch the gait deviation during the day, which is never more than two seconds. I set it up a week ago and it’s now in a hurry for a total of a second. For 60 euros ... (Vostok Amphibia cal. 2416b)
