I've got a Calibre 8700 that runs fast maybe +4/5 seconds per month. Usually use that to sync my Autos.

Hello!
I'm new around here, so I didn't want to post a new thread, but I'm not sure i'm using the right one neither.
Recently I received a Citizen Eco-drive AW00500-82E and is not on my wrist, first i'm trying to see what is the accuracy, so far looks like is around +2 seconds per week(I was expected more like +/- 2 seconds per month), and I wonder if anybody around here knows if this watch have inside an adjustment for setting the time faster or slower. I remember when I was young, my first watch had that adjustment (sorry can't remember the name of the watch), inside the watch had a little pin that you were able to move it towards the + or -.
Thank you!

Why would you expect +/- 2 seconds a month when the stated accuracy is +/-15 a month? +/- 2 a week is still about twice as good as what it is specced for.

...and I wonder if anybody around here knows if this watch have inside an adjustment for setting the time faster or slower.

Short answer - No.

Thank you for your reply.
I didn't know the watch, or any watch, have a "stated accuracy", I thought a good watch (better than Citizen) is more accurate, no more than +/- 10 seconds a year. I guess all this time I was wrong.

My Citizen Eco-Drive watches, a Euro Nighthawk and a JDM Promaster Diver, both run about 2 seconds a week fast so it sounds about right. Better 10s fast than 2s slow!

Citizen does make HAQ watches that are +\-10 seconds per year (like the AQ1030) but they are in another realm pricewise from most of their models.

Glad to know that after 10 years Citizen has improved their watches's accuracy a bit :-d

I have got a Citizen Eco Drive BM8476 15XE last xmas. So far so good. I synchronized it to the online atomic clock and hasn't lost a second.
Lighting in the dark is pretty good, considering it is not fully charged and didn't get much sunlight.

I've had over 30 Eco-Drives, many of them JDM Exceed models rated at 10 sec/year accuracy, and they have all met that spec. Most of the 'normal' ones keep relatively decent time, 5-10 sec a month, some even better, it's very much luck of the draw, but they all meet their spec. Accuracy is not specifically related to the cost of the watch, the materials, finishing, dial work, etc. will all have an impact on the price. There's no promise a $1000 quartz watch is going to be any more accurate than a $15 Timex, much of the time, it's often luck of the draw, unless the watch is specifically designed/built/spec'd to be a high accuracy model.

Ok so it hasn't lost a second, very good and I'll presume it's gained some number of seconds then.

I have unbelievable accuracy with my Eco-drive watch. My times are always +-1 second. It usually loses a second then gains it back or vice versa. Depends on how well the watch you get is made mostly. I also wear mines 24/7, which may make a difference.

Of the many quartz watches I've owned on top of the many user experiences posted here yours is the first and only one I've ever heard that both gains and loses time.

I'm stunned by my eco-drives, which never seem to vary by much more than 1-2 seconds per month. I've got a bunch of mechanicals (from Omega to Longines to Hamilton to cheaper ones - and I have huge affection for them) and a few quartz (Victorinox, Seiko) but - in my experience - the eco-drive is in a different league entirely. I've got one from 1997 and it's still powering along as good as the day I bought it. It surely has to give out at some point, but it's not today, apparently...
