The case is a modest 38.5mm across (the perfect size for a watch like this, if you ask me) and the dial utilizes what have become the design codes of the 1815 collection, with the slightly fancy Arabic numerals and the outer chapter ring. With the running seconds, power reserve indicator, and oversized tourbillon opening and bridge at six o’clock, this watch ends up looking kind of complicated, despite basically showing just the time. For the movement, Lange pulled out all the stops. There are 953 components (including the 633 used to make the chain for the fusée-and-chain mechanism), finishing is off-the-charts good, and there are a pair of diamonds used as the endstones for the tourbillon (something that would become a signature for the PLM watches).
