While I was typing it up this thought popped into my head; "A Prius is more electric than mechanical. A Tesla is all electric. Teslas have caught on fire and burned up. Hmmmm...maybe I should stop typing. Nah, go for it!" :lol:

Where in CLT does your brother work? I'm a Nurse Practitioner and work in the Lake Norman area.

Mine was running +35 sec out of the box. CW offered to have it regulated and sent it back within a week. It's now at +2/day

I did this earlier as I've only just got the submarine one. Bit if OCD I guess. Ones the trident COSC the other a trident pro. Both set identically earlier today with my iphone. Let's see how they drift.

Back to this topic, on which I did contribute something nearly two years ago.

I've now had my C60 just over two years, and it's still gaining. Less so than before, but noticeably. I've just monitored it over a week, using this site ( http://www.timeanddate.com/worldclock/uk/london) as my reference, and in 7 days it has gained 50 seconds - so that's just about 7 seconds a day, and indeed the daily increase was regular and very close to that. In the two years since it was new I've worn it almost every day an in all that time I think it has only run down once, and then only for a few hours. So it's well run-in.

Now I'd appreciate some advice, please. Is this 'normal', now that the watch has left the first flush of its youth? I don't know because I have no experience of automatic watches other than with this one. (My C5 MkII is not often worn so it spends most of its time stopped.) I know it's not a COSC-guaranteed watch so it's not going to be spot-on accurate, but I do feel that I would like it to be more accurate than it is; it would be good to be resetting it once every couple of months instead of once every couple of weeks. Or am I expecting too much? Advice, please.

To be honest, 7 seconds per day is pretty good for a non-COSC mechanical watch and well within tolerance. So the watch seems fine. Just re-jig it once a week, eg as a Sunday morning task. :)

At its current rate, your watch is operating just fine. Regulation might improve it, but seriously....+7 sec per day is great. the specs call for a -10 to +20 range.

If you want more accuracy then either regulation, COSC, quartz or quartz COSC is in the cards for you.

Thanks for the information, welshlad and Kip - I really didn't know what it was reasonable to expect and what it wasn't. Now I do, so I'm happy.

COSC is -4 to +6 seconds a day so +7 is quite close to COSC specs.

I have been at this watch thing not for long (had them...then came iphone...now back to wearing them).

What I find bit hard to understand is, how close does it have to be in keeping accurate time? Assuming COSC standard if it falls behind 5 sec every day its a minute behind in 12 days (or 15). I mean how many keep the same watch on for 15 days anyway? We, materialistically spoiled generation change our watches every couple of days! And when I measure my daughters swimming speed, I would pick the stop watch on iphone any day!
