A.Lange & Sohne Grand Lange 1 Lumen Watch

A.Lange & Sohne will launch its ultra limited edition timepiece called Grand Lange 1 Lumen next year. There will only be 200 pieces to be offered to the public. This timepiece is a combination of ideas that only A. Lange & Sohne is capable to transfer to real life. This watch uses ideas of past models from the brand. By doing this, the brand ensures a perfect mix and variety in this timepiece´s design.

The Grande Lange 1 Lumen is privileged with a 40.9mm case made of pure platinum and it has an amazing 9.8mm of thickness.

This beauty is powered with an incredibly high end caliber, Lange L095 2 that has an impeccable 72 hour power reserve. Its plates and bridges are equipped with incredibly polished German silver. The balance cock is fully hand engraved and let´s not forget about its platinum buckle.

The outer ring and the surface of the hours and minutes are made of a rare sort of black silver. The almost transparent crystal made of pure sapphire reveals beautifully the mechanism of the luminous date. The power reserve and time can also be seen in the dark.

A.Lange & Sohne treated the sapphire crystal of the dial with a very rare coating that works as a barrier for most rays of light.

The greatest technical challenge found while developing this piece of art was to find a way to keep the most luminosity to display the date. The developers found an answer to this riddle in a very interesting way. They realized that they could use a white luminous compound and use black numbers with a similar compound and then those will rotate on a glass (transparent) with a luminous compound.

We can conclude that this timepiece is very interesting because of the nice features it has to offer. It includes 42 jewels and 7 screwed chatons made of pure gold. It comes with a very fine black crocodile strap that suits this timepiece perfectly.
