How about the precision of Dornbluth watches...

View previous topic View next topic Go down  Message [Page 1 of 1]

I thought that it would be interesting to start a topic about the precision in timekeeping of the Dornbluth watches. Why? Because, in my opinion, the beauty of a watch is very much about how well it keeps time...this is the first purpose of a watch, to measure time...a beautiful looking watch means nothing if it doesn't have the ability to tell the time within a reasonable margin of accuracy. So...did anybody tested his or her watch?

2 Fine idea! on Thu Apr 30, 2009 7:34 pm

I don't know much about precision, but my sense is that my Dornblüths are at least as accurate as any other mechanical watches in my collection.

Can you establish the parameters for testing accuracy? It would be very interesting (and maybe helpful to Dirk) to compile the results.

Cheers!

3 Parameters for testing accuracy... on Fri May 01, 2009 7:39 pm

I wear my Dornbluth every day, seven days(and nights) a week, so in testing accuracy, for me, the only parameter that matters is how the watch perform on the wrist. As for the reference timekeeper, I use the internet GMT time (see the GMT official site), which they say is accurate within 1 second. I know that there are other scientific methods for testing accuracy of a watch... but, as I mentioned before, for me, the whole purpose and beauty of a watch is to wear it (I don't believe in a beautiful handcrafted but unwearable watch...I've seen some of those at Basel last year).
Now, about my own cal.04.0...when I received the watch, it ran about +4 sec/day, but the difference increased suddenly to +20 sec/day, after I did not wear the watch for almost 2 months...this margin of error remained for a while but again, after not wearing the watch for a couple of days, the difference reached +26 sec/day...this is a little bit strange but not very annoying.
So, I'm looking forward to read your experience regarding this matter.

Her is a link to a comparison between iwc and dornbluth. The weak side of dornbluth seems to be the accuracy. But this might have changed since 2006..

This is the answer on accuracy I received from Dirk Dornblueth:

"Our watches are delivered in -2/+6 sec per day. We have a testing period of several days here to regulate the timepiece.
But there are different wearing behaviours of the individual client, which have influence on the results, but our experiences tell us, that the difference will be in this area"

That's a very interesting article, Pichao, thanks for posting the link.

I have my 99.1 form December 2008. At the moment it loose 2 secs per day. I think it's a great timekeeping.
