I have had my watch for a couple of days now, a Senator Perpetual, and in the last 24hrs it has gained 15 seconds (5 seconds overnight in upright position in case, and 10 seconds on wrist).

 

When I asked the question about accuracy with GO, this is the response I got direct from them:

 

 “Automatic watches are tested in five positions and the permissible range for the average daily inaccuracy of automatic watches is between -5 and +10 seconds per day at a temperature of 20-25 degrees.

Manual winding watches are tested according the Chronometer ISO standard. In case of automatic watches, it doesn’t make sense because they are permanently and differently actuated. The Chronometer ISO standard is more intended for non-moving watches like our manual winding time pieces.”

I’m going to give it a while for the movement to settle down, before I get an average for my watch. As comparison to Swiss Chronometers, I own an Omega Planet Ocean with Co-axial movement, which was 7 seconds per day fast, sent it back for regulating under warranty and is now +1/2 seconds per day. Also have a Rolex which is +2/3secs per day.

Did your watch take time to settle down from new? If so, how long and what was the rate variance?

 

Thanks,

As for a new wtch, you have to wait a bit before judging its accuracy...Let's say a month.
Then, if it is not accurate, which is very relative for a mechanical watch, in comparison with a quartz watch, you can get it back for your AD to set it more accurately...
You'll have to know that in important factor is the way the wearer lives with his watch...Is the wearer a quite person, or a more active one???
Frequently a watch has to bet set to the owner...
So, do not desperate...
As for mine, the Senator Navigator, for the moment, it is weavering between one and 2 sec per day, but it doesn't mean that after 3 or 4 weeks, it will be the same.I'll see.

i've got 4 GOs and the fastest one is at +8 but that watch is about 6 years old. Most were +2-4 when new.
Give it a month or so to settle. After wearing a new watch for while we tend to stop picking on the accuracy and enjoy the watch more!

. . . was excellent right out of the box, and although I haven't performed any rigorous tests yet, it seems to be ~ +1 sec/day. I have a fair amount of experience with the cal 39 automatics, and they've exhibited a wide range of timing accuracy, but they've also exhibited a very high degree of rate stability. For example, my second G O was a Senator power reserve that ran +21 sec/day right out of the box, and was about the same when I sent it in for service after four years; it came back adjusted to +8 sec/day, and remained there until I parted with it several months later. My first G O was a cal 39 Karree chrono that essentially ran perfectly out of the box when I acquired it in 2001, and was running perfectly when I sold it a few years later; it gained ~ 60 seconds over an 18 week period when it was continuously either on my wrist or a winder - performance which borders on the phenomenal. My second Karree perpetual ran ~ -8 sec/day out of the box when I acquired it in late 2004, and only lately have I noticed a slight improvement in timing performance (which might be an indication that it's time for service!). I don't have any experience with the cal 100, but I'd let it settle in for a few months before sending it back for regulation . . . +15 sec/day is not acceptable, in my opinion, for a modern watch, so keep tabs on it for the next several weeks so you can give G O a meaningful report of the timing performance if it doesn't improve with break-in. Cordially, Art

Own my Senator Perpetual Calendar (Cal 100) for about 3 weeks now and the watch had been gaining approx'ly 20 sec/day out of the box despite my trying of different resting postions, placing it on my Orbita or Underwood winders and wearing.  By far, this is the worst results I have seen from my small GO collections.

Gave up and just sent it back to the AD for regulation.  May take up to a month to get the watch back as my AD claimed that most of the local watchmakers had gone to Basel.  Will update you on the matter once I get my watch back.
