What monthly spring drive accuracy numbers you getting?

[samson66]

Just finished up my 30th day of tracking my new-to-me SBGA001. Figured since it's my first spring drive I'd keep a close eye on it and see what it is capable of.

This is what I wound up getting after day 30

+7.4 seconds for the month
+.02 seconds/day average

Most accurate watch I own. Curious what kind of numbers you guys are getting on your spring drives? I'm pretty impressed so far

Beautiful watch, congratulations on it.

I recently picked up my first spring drive (and first GS, ha), the SBGA415 "Winter" model, just over a month ago. I haven't checked the accuracy as rigorously as you have, but anecdotally I reset the watch once approximately 17 days ago and since that time it has gained 5 total seconds, making the daily accuracy somewhere around 0.3 sec/day. It's the most accurate mechanical watch I've ever owned.

A hair over +8 for calendar August (Snowflake).

My most accurate watch in my Speedmaster. I just checked right now, I'm +2 seconds since I reset the time around the 4th of July. I do wind it every morning, even if I don't wear it that day.

I think that is remarkable, especially for a non spring drive.

edit: sorry to hijack the Spring Drive topic.

I suspect you mean +0.2 sec/day and not +0.02 sec/day .

BTW, it's the same accuracy I'm seeing with my solar Tuna, which is a regular quartz with no mechanical parts involved. Kudos to SD, then!

Yes thank you for pointing that out. +0.2 sec/day according to the app. Although works out to +0.247 sec/day over 30 days to be exact.

I've never timed my g-shock but it seems like it's in the same general ballpark judging from the times I've reset it.

Good to know the spring drives and right up there with a standard quartz watch for accuracy.

My 9F quartz has gone -/+ 0.00 for more than six months now.

Well it's hard to beat THAT number

Damn that's a beautiful, clean looking watch. Love that it shows the day and date.

Thanks, yes it's one of the few watches I've bought from a store on impulse. Spotted it in a Seiko dealer in Hiroshima a few years ago, and couldn't resist. I've worn it most days since.

In my case the G is much worse wrt accuracy. About half a second per day fast, in line with the declared spec.

The new SLGA007 is between 0 and 0.1 s/day accuracy.

[Moondoggy]

My new SBGA469 I set the time exactly with seconds at 12, I reckon in five days it is out about half a second.....pretty darn good!

Love lining up the swordfish hands with my imac clock on the minute.

My Seiko Prospex LX SNR041 gains .08 secs/day. It’s gained 2.7 seconds in 32 days. I have 4 Spring Drives and this is the most accurate. My least accurate is an SNR031. It runs at 0.3 secs/day.
They’re all amazing. They’re all I wear. I’m a convert…….

Here’s my graph from my timing app.

Is awesome, I’ve had my new spring drive on for six days and the accuracy is taking over my existence always checking, my other watches are in retirement.

How I have lived for this long without such accuracy I do not know. It’s insane.

Ten months now and still dead on.

I know. It’s easy to get spoiled. I actually really like the power reserve indicator as well. I use them more than I expected to.

Nice pix Adam

Could you improve the accuracy with a new battery?

Thanks Eddie. It had a free battery change and pressure test last year. Before that it would lose a second every couple of months, but the 9F can be regulated quite easliy and I'm guessing the service centre tweaked it at the time.

I'm hoping it'll do the full 12 months

I think there's a very good chance you will. On another forum I read a March 2121 post by someone who purchased and set an SBGN007 (which is what I have) in July 2019 and now - slightly short of 2 years later - he is accurate within 1/2 a second. My own SBGN007 is now 55 days since I set it and it's MAYBE .02 seconds ahead. That would annualize to .14 seconds over a year if it keeps it up. The 9F movement is really something special; GS watches seem to under promise and over deliver.

[guber]

SLGA007 is getting me 0-0.1 seconds per day so far.

[Pius XIII]

It’s been 24 days since I last set the time on my SLGA007. It’s still dead on.

[samson66]

I'm only four days into my SBGE253 ownership but so far it is spot on. SD is amazing
