A. Lange & Söhne has again proved their talents in watch designing and making by presenting the Lange 31, the first mechanical wristwatch in the world that is capable of a 31-day power reserve. And another striking point lie in the patented constant-force escapement that is able to power the going train with constant torque delivery. Lange 31 also provides the highest quality rate stability and rate accuracy for a whole month.
So you forget the winding your watch quite often? It’s kind of alright here, since the Lange 31 has an autonomy system enabling it to show the right time for 31 days. Take a closer look at that sapphire-crystal backside, and you can see the key-winding mechanism, another element to guarantee precision, which has rarely been found in watchmaking. Besides, this mechanism brings more precise winding transmission ratio than a crown.
Three seals protecting the watch against water are found between the winding mechanism and the case, which can withstand maximum 3 bar pressure. Five to ten times longer than the springs of regular mechanical wristwatches, the two mainsprings have compound energy of more than 3 joules, with a total length of 3700 mm.
Aside from the innovative movement, this timepiece has also performed greatly in aesthetic value. The platinum model features a solid silver and rhodié dial, and rhodiumed gold hands and platinum deployant buckle. Then the model in 18-carat pink gold has got a solid-gold deployant buckle, a dial made of solid silver, argenté and hands of pink gold. The models both come with a hand-stitched crocodile strap, elegant and durable. Traditional elements of the house have also been displayed, like the whiplash precision index adjuster on the balance cock and the three screwed gold chatons.
So how can you miss such an A. Lange & Söhne Lange watch which is so superbly done? But if the price is a problem to you, try the high quality replica ones which will not let you down, either.
