The jewel bearing of the retrograde minute hand ...
... is typical for Rainer Nienaber, and serves the purpose to reduce the wear on that piece as much as possible. The main problem common to all retrograde indications is the massive wear, resulting from the hand's high speed, abruptly decelerating when returning to the start point. Over the years, this normally results in a maladjustment, sometimes even a massive failure. Bearing the hand in a jewel, additionally with other systems to reduce the negative effects of the mass inertia, such as brakes, and very low mass of the hands, helps to keep the system working flawlessly over decades.

Marcus, I very much like...
...the dial on your Rainer Nienaber. The contrasting guilloche patterns are beautiful and eye-catching. One thing that I noticed in the next to last photo is that the minute hand appears attached to a jewel on the outside of the dial. Is this a signature ...

Thanks for the info, Marcus.
I like that the use of the jewel on the outside of the dial is not only aesthetically pleasing, but also functional. That's fantastic. Cheers, Daos
I like the Chronoswiss Chronoscope
It's a nice simple watch with the most beautiful thin hands. A watch that is very under the radar IMO. Cheers, Anthony...
