My new Sinn..gained 10 seconds since setting it yesterday..oh no

[thodgins]

I am very impressed with Sinn and Sinn's overall construction. I am so glad I looked at their website and bought this model, 103 A Sa Hd. I have a feeling more Sinn watches will be in the collection down the road.

As far as the 10 seconds or so, I am not overall concerned with the accuracy. Any thoughts on hand wind watches and accuracy?

Don't sweat it. My U1 was about +5 per day when I got it and it's settled to
-3 per. You may end up with a really good +2 or so.

As it is new you should allow at least 3 months of daily wear to assess its accuracy. You'll find that it should settle down. to 2-3 secs a day +/-

I qwould give it some time as well but 10 seconds a day is not too bad in my book.

Like everyone else said....+10 seconds = no worries.|>


enjoy the watch!

That is interesting. Thus far my new Sin 103 A St Hd has been slow about -2 sec/day. I set it up again tonight for more timing measurements.

It is funny how a watch from the same maker and exact same watch can run at different times. I read 2 reviews about the Eberhard Traversetolo and one reviewer said he had gained 30 seconds per day and the other said 8 or so seconds. As I was thinking about that watch, a guy told me his ran slow. Who knows why that is. It is interesting.

From I what little I know, Sinn watch movement is from ETA (high grade) but unmodified. As such, it is not Sinn's fault that your watch run "fast" or "slow" :-D

In fact, as suggested by others and even Sinn, there is a break-in period and afterwhich a deviation of 10 seconds is quite acceptable for automatic watches.

Aloha!

And I have revived this thread just to point out that a mechanical watch movement is basically a living thing....it is not as if you set it one day and it stays exactly like that forever. It is constantly changing...

As the temperature changes..

In different positions....

At different altitudes....

as the lubricants change over time....

as friction causes parts to wear...

as you drop it, bang it, whack it, smack it, and take it 75 feet under the ocean.....

how about the absolute accuracy of the watchmakers timing machine?

And although my computer checks the NIST atomic clock when I log in, sometimes I am logged in for several days or hours and thus my computer clock is inaccuracte.

Even the 10 atomic clocks running around the world all feed into one "master" clock in Paris that decides what time it -ahem- REALLY is. :-d
I assume that there are small differences between the clocks or this would not be needed.

And it's still not clear to me how they originally set the atomic clocks in the first place back in the 50's and 60's. I'm sure they used the Navy's USNO clock/GMT based on earth's motion, but even this can be off by several milliseconds per day. I know they set up UTC in 1972, but still it seems to me that at some point someone had to make the call..."NOW!" or "MARK" or whatever.

OK back to work...

Cheers,
John

wear in is an accepted norm and with a hand wind it is even more so.
after a few times of full wind and run down if it doesn't settle in at 5 sec +- then i would be concerned.
