The specs on an unregulated sellita SW200 is +/- 20spd. I think +10spd is totally reasonable. It’s luck of the draw with non chronometer watches to get less. My C60 is + 8spd and I’m thrilled with it.

I’ve owned probably 30 auto watches and +10spd is about par for the course. I’ve had a Seiko SKX that was about +30spd (still within specs)

My new C60 GMT is running about 2.5 secs a day over the last 8 days, which I am very pleased with.

This C65 Trident Diver has been running for a few days now, and will probably be on my wrist all week if the weather stays nice. Seems to be running at around +2 s/d.

I've had my Trident Pro 38mm for about five or six years now.
It's always been running at about -10 seconds per day.
It's my only watch so gets worn every day for all activities.

I own a good number of automatic watches, some of them chronometers and some not. It’s really the luck of the draw. My Marathon GSAR keeps to around +2 seconds per day while the new C60 Sapphire dark hovers closer to +9—both of them feature the Sw200-1 movement. My certified chronometers are generally more accurate, though I have a number of non-chronometers that seem to keep accurate time, too.

+10 seconds a day seems pretty high. As a reference point, I've had near-perfect accuracy with my Rolex Datejust(+/-3 seconds) and very good accuracy with my automatic Cartier (+/-5 seconds).

+10 seconds is well within tolerance on a non cosc movement. Your reference point is fine with similar luxury brands but to reference average affordable auto's against a Rolex and a Cartier is setting the expectation too high.

Always happy to welcome a fellow Cartier owner! :D

There are 86400 seconds in a day and a watch running at +/- 10 seconds per day equates to an accuracy rate of:

86390/86400 x 100 = 99.98% accurate.

I'm struggling to see the problem here.

I used to get wrapped up in auto accuracy, often comparing them to quartz watches. They are not the same animal and, when you give it some serious thought, what does it matter if the watch gains or loses 60 or so seconds a week. Scooter's mathematical breakdown perfectly illustrates the point Once you start embracing all the other aspects of a mechanical watch 10s here or there is of little or no consequence, unless it's a chronometer we're talking about of course.

My C65 Dartmouth has been +1s per day over the past few days that I’ve checked, not too shabby even though it is COSC.

I've given up trying to understand the accuracy of my CW automatic watches. They are creatures with a life of there own. One day they are within 5 secs of when set to then a day later they are 30 sec's slow as an example. I would say you need to wear them for the best way to get the best average accuracy

Just to add has anyone else given up on time.is since they added adverts which makes the accuracy useless? For reference I use clock.zone now and will stick with that site due to no adverts
