White metal, black dial. This is what so many look for when considering a high-end chronograph. The Datograph Up/Down, a staple of high-end chronographery (is that a word? no, but it should be) hit on that, and the platinum case plus black dial coupled with arguably the sexiest damn movement in all of watchmaking made it a quick classic. But the Datograph isn’t perfect for all; nay, some prefer its slightly thinner, slightly more slender little brother, the 1815 chronograph. I am, in fact, one of those people, and an original 1815 chronograph in white gold remains part of my core collection to this day. I am, not shockingly, wearing it as I write this story.
