3 seconds

[Blue Shadow]

So I synced up my DJ to www.time.gov yesterday at 4pm. I just checked it and my DJ is 3 seconds slow in a 24 hour period....not too bad I guess!

Right where it should be...

I don't care for slow but it is in the range for COSC.

Check it after a week and then average it out. If your watch averages a variance within COSC, you should be ok.

[Bob70]

sounds ok to me.

Not too bad at all, my GMT-IIc is also about 2-3 seconds slow per day. I much prefer my watches to run slightly fast however.. But i'm waiting for my first servicing to have it adjusted.

Just checked mine too. I'm still running +6 seconds per day. Still within specs, I understand.

If I had one within COSC, I'd be very happy. One of my watches was running about -20 since servicing about 6 months ago. I've been keeping tract of the accuracy for all that time. That one watch kinda got me obsessed with accuracy. But now that it's back to the watchmaker for checkup and regulation again, I find that my obsession with accuracy is gone. A watch should be worn for enjoyment, not to display accurate time IMHO. I'm looking forward to getting it back, and hopefully, it will be within COSC, and I'll wear it with pride. It's a beautiful, classic 5512.

It is important to understand that a new watch off the shelf may need a break-in period of a month or so to settle in.Now this allows the watch to find its true beat rate and distribute the oils evenly around the moving parts. If you find your watch not to be as accurate as you would expect after the break-in period, there are generally two courses of action to take to increase the accuracy, both very minor in nature,but require any good competent watchmaker to do it.Now if your watch runs consistently too fast or too slow remember the keyword being consistent. The solution for the watchmaker would be to regulate the true beat rate accordingly plus or minus.Now this is a very simple and quick procedure achieved by turning Microstella adjustment nuts and screws.And with the use of a time-measuring machinery a good watchmaker can accomplish this in a matter of minutes I just cannot understand why they send watches back to the RSC for such a simple task. Regulating is most probably one of the most common tasks for any watchmaker to do.Now when a watch is fast or slow or does not have a consistent rate, especially in different positions.Then the balance wheel needs to be adjusted further to compensate for the different positions. Although this too is a simple procedure, it does require a little more time to correct as each position needs to be monitored and adjusted carefully.But don't be in a hurry to get the back off for a few seconds either way its not life threatening to be a few seconds off COSC spec.

Glad you have seen a bit of common sense and your obsession with accuracy has gone now you can fully enjoy your watch.

My Explorer runs about +3/day on average.

Here's the numbers from my AD on my new DJ.

I really haven't timed it for myself, except to glance at it from time to time against my radio-controlled clock. It's running at least this good. This was done on the day I picked up the watch.
