These features are all thanks to the new A. Lange & Sohne caliber L102.1 in-house made and decorated manually wound movement. The movement contains 262 parts and operates at 21,600 bph (3Hz) with a power reserve of 72 hours. You know what would have really sweetened the deal? A power reserve indicator on the rear of the movement (or side of the case).

Being that this is a higher-end watch in an already high-end brand, A. Lange & Sohne places a diamond end stone on the rear of the tourbillon palette as opposed to a synthetic ruby. You can see it through the rear of the case at the end of the hand-engraved balance cock. It pretty much goes without saying that as a Lange, the movement is beautiful, and in this instance I really appreciated the simplicity and three-dimensionality of it as well.

On the wrist, I would normally have no interest in a 39.5mm wide watch but somehow the 1815 Tourbillon makes a compelling case for itself. It is a calm, comfortable design enhanced for a more enthusiastic collector with the addition of the tourbillon, though the simple legibility of the design is not that obstructed by its inclusion. The watch isn’t that thick either, being about 11mm in thickness.

A. Lange & Sohne will offer two versions of the 1815 Tourbillon. First is the standard ref. 730.032 in 18k pink gold. It comes on a brown crocodile strap. There is also a limited edition of 100 pieces ref. 730.025 version in solid platinum matched to a black crocodile strap. Price for the A. Lange & Sohne 1815 Tourbillon is $164,100 in 18k pink gold and $201,300 for the limited platinum model. alange-soehne.com
