Richard Lange, to be precise. I have never even tried on a A. Lange & Sohne. I have always liked the Lange 1. Just recently I have started researching the various models a bit. One of my favorites is the rose gold black dial 1815 Chronograph, which seems to now be discontinued. The Datos are spectacular. Also like the L1 Timezone. Not sure I like the Grand L1 as much as the regular L1, although the Luminous model seems to work nicely in that range.
But I keep circling back to the Richard Lange. What a beautiful watch.
Great forum here guys. Hope to join you guys soon w/ a piece of my own
