But this isn't just a black dial version of the current 1815, it's a black pulsation dial, or a tweak to the boutique edition 1815 that was introduced in September of 2015. Now that watch, of course, was inspired by the very first 1815 chronograph from 2004, which had a pulsation dial in silver with a white gold case and a black pulsation dial with the rose gold variant. This is the first time Lange has offered a black pulsation dial in a white metal case, and the combination is one that is hard to ignore. What makes the piece even more compelling is, quite frankly, the other side to the watch, which has been described by our own Kevin Rose as "A little city back there." The caliber is simply spectacular, and there isn't a single person that would dispute the claim that this chronograph is among the finest ever produced. With this new watch, nothing has changed, and you'll still have the wonderful view from behind.
