Pure class Tony. I actually think this rosr gold version of the 1815 chrono is my favorite, even more so than the Datograph version in RG due to the purity of the dial, without the date 🔥🔥 [nt]
The colour of the Up/Down indicator and the date window discs throws off that purity for the Dato. We are of course splitting hairs at this point, both watches could the be the apex of any collection.
I have a very weak spot for watches that we can relate with our professions. This is what happened to me with the Milgauss. Have a great weekend Tony! Alex
