Here is something you don't see everyday. The Toubrograph "Pour le Merite" by Saxony's A. Lange & Sohne was the second watch by the high-class watch maker to bear the "Pour le Merite" badge. The available model is of the rarest, in platinum, with just 51 pieces made. The watch was released in 2005 with an incredible reception. Despite the fact that A. Lange & Sohne watches are often very similar in character, it is the small differences that each new model bears that are intriguing. The watch company defines conservation, when it comes to keeping high-end watch *** a purists' art form.The Tourbograph "Pour le Merite" features a world's first combination of desirable complications. It had a one minute tourbillon, a fusee and chain escapement, and a rattrapante chronograph, along with a power reserve indicator. All in a very *** looking, but mechanically complex package. The watch itself has over 1000 parts inside, each carefully finished by hand. The split second or 'rattrapante' chronograph is a 30 minute counter that can split between two time. That is why the watch has two chronograph seconds hands. Manufacturing, decorating, constructing, and testing of each tourbograph "Pour le Merite" watches takes well over a year. So even though the limited edition was release in 2005, Lange is still likely *** them today, even with such a limited run.Despite the ultra luxury status of the watch, when you handle it, you don't immediately think "I should really be careful with this." It doesn't come across as delicate, but rather as a very well put together watch utterly capable of being worn and relied upon daily. Given its value, and the fact this this is what I call an "investment grade" watch, I wouldn't recommend wearing it so often though. Right now, one of these very rare A. Lange & Sohne Tourbograph "Pour le Merite" watches is available on JamesList. Price? Well it is high, very high, but this is the type of watch that can command such a value. Like I said, they are investment grade watches meaning that they are among the few watches in the world with the ability to appreciate in price. The watch is being offered now at about 685,000 Euros.

The talented watchmakers at A. Lange & Sohne created Large 31, the first mechanical wristwatch in the world with a 31 days power reserve and a patented constant-force escapement able to power the going train with constant torque delivery. Lange 31 transcends the notion of power reserve while keeping the same high Lange standards and providing highest quality rate stability and rate accuracy for an entire month.The Lange 31 has an unmatched autonomy that allows you to forget winding it from time to time. The watch shows the right time for 31 days even if you take it off, a special function emphasized by the solid-silver dial engraved with the inscription "Monats-Werk". On the right hand side of the solid-silver dial, an ample indicator displays the power reserve. The left hand side is balanced with a stylish patented outsize date. A closer look at the sapphire-crystal backside of Lange 31 discloses the key-winding mechanism, another precision element rarely found in watch*** that was specially designed and constructed to match Lange 31. This mechanism permits more precise winding transmission ratio than a crown. Consequently fewer revolutions are required and more energy saved. Between the winding mechanism and the case there are three seals protecting the watch against water with maximum 3 bar pressure. The key is introduced through an opening in the sapphire-crystal case-back and has an integrated torque limiter that prevents damages of the mainsprings. In the moment the mainspring is entirely wound, any attempt to turn the key releases the triangular toothing of the two wheels and stops the power flow. The Lange 31 features a powerful L034.1 calibre stored in a 37.3 mm diameter and 9.6 mm height space. The energy storage function is provided by two stacked spring barrels which incorporate the two mainsprings. These two mainsprings are five to ten times longer than the springs of regular mechanical wristwatches and their compound energy is more than 3 joules, as their total length is 3700 mm. A constant force escapement controls the power delivery. It has a pretensioned spiral spring that instantly retightens on the fly every ten seconds. In a controlled way, the next ten seconds the stored energy from the spring is sent to the going train while the torque output constantly powers the watch to function for a month.In addition to the innovative movement, the aesthetic enhances the value of this timepiece. The model in platinum has a solid silver and rhodi�� dial, as well as rhodiumed gold hands and platinum deployant buckle. The model in 18-carat pink gold has a solid-gold deployant buckle, the dial made of solid silver, argent�� and the hands are pink gold. Both models have hand-stitched crocodile strap. Traditional Lange elements such as three screwed gold chatons and the whiplash precision index adjuster on the balance cock are also present. All finishes are superbly done.
