- What do you think about this mecanism compared to the stop second? I understand it is more easy to correct hands for the exact time with this system. Thanks for sharing your experiences and thoughts. - Is there only Saxonia automatic and Grande Saxonia ... 

It may make setting the watch slightly more convenient, but frankly it's not that hard to do with a normal hacking movement. It's importance is mostly that it is evidence of Lange always insisting on doing everything a little better than the competition. ... 

certainly great for setting time precisely .I like this feature very much.Two more that spring to mind>Glasshutte Original Senator Chronometer and the new JLC Duometre a Quantieme Lunaire.Mo

watches you mentionned to learn further on them. Cheers, patrickh

BUT, and a very big one at this, is that unfortunately for me it exists ONLY as part of Lange's automatic systems, and that is a very BIG NO NO for me.... Crying my worth off here,..... Stephen

JLC and Glashutte are manual winding. Thanks for your comments on the zero-reset system. Cheers, Patrickh

A zero restart is the best solution for accurary. Because the balance wheel doesn't stop. When it stops, it needs a few minutes to find again its right amplitude. A zero-restart doesn't have this trouble. Fr.Xavier...

There are some people with F.P. Journe Resonance watches where one balance wheel doesn't line up with the other balance wheel for a few days. Thus, I think the shock of restarting the balance wheel will require it to take a few minutes to re-adapt. The ba...

On the Sax O Mat system, the balance wheel is fully stopped, thus, when restarted, the balance wheel takes some time to find its original rate again. It is better to have a zero-reset system that does not require the balance wheel to stop.

means zero reset system, which is included in the saxonia automatic models. Maybe I am wrong. Thanks to give me some clarifications Best regards, Patrick H

One of the attributes of the Sax O Mat system is that the second hand resets and stops. This stopping part is what I'm referring to as being detrimental to the watch's rate and accuracy. The reset system itself does not affect the watch's rate and accurac... 

have a pure zero-reset? Does it exist? Cheers, Patrick H

All the Sax O Mat have a zero reset. What are you referring to as "pure zero-reset" ? I'm not following your terminology here... To my knowledge, there isn't a watch that has both a zero reset and a hacking seconds where the balance wheel and hairspring a... 

Sorry to do not know the correct term to describe this mecanism. Cheers, patrickh

2010 Saxonia annual calendar also have this zero-reset mecanism. A great implementation for accuracy from Lange. Do you have one model with this system? Cheers, Patrickh
