Ulysee Nardin Marine Chronometer
A customer brought this in to me at my booth in the antique store. His intent is to sell it, and he asked me to check it out for function. I was trying to find a listing for Ulysee Nardin marine chronometer serial numbers, but most responses to my internet search turned out to be for watches. Does anyone have information on or a lead to where I can find information?

When I turned it over to wind it, I found this which I would guess means that it saw service during the time of Nazi Germany. The movement may have been made earlier. So I am trying to find a the actual date of this chronometer.

I am sure the company can provide you with some good information. If you would like more detail on German ships chronometers and other German military timepieces there is a definitive reference book on the full range of timepieces used by the German military that was a labor of love by Dr. Konrad Knirim: German Military Timepieces; 150 Years Watches and Clocks of German Forces ISBN 3-89355-232-4 You can buy this huge reference book from him directly at his website Konrad is a member of this forum he stops by once in a while as well.

I received this response from Julien Lovis
"According to our archives, your ship chronometer was made in 1944 and sold to Deutsche Seewarte, Gesundbrünnen.

The Deutsche Seewarte (German Naval Observatory), Hamburg was founded in 1878. It was responsible for making marine observations and geomagnetic observations. Gesundbrunnen is in Northern Berlin, and perhaps operations in Hamburg moved there in 1944. After the Second World War the operations were merged into German Hydrographic Institute, which was renamed the Federal Maritime and Hydrographic Agency in 1990.

I have run the clock. It is slightly out of beat, but came in about 10 seconds slow over 24 hours.

Thank you for sharing your collecting information.
Very impressive and comprehensive .
I agree that it is the people you meet that make the hobby so satisfying .
Did the German military record the assigned vessel for each timepiece ?
