The Lange 31 Watch Equals 31 Day of Power
the lange 31 by a. lange & sohne came out last year as the world’s first watch with a 31 day power reserve. the key to the 31 day power reserve is the energy balance. the energy i men’s tagheuer s not only pulled from the battery but also from the movement which includes a winding key stored in a twin mainspring barrel.
this concept of using the movement as a power source has become popular recently including in the perrelet diamond flower watch which uses the wearers movement as additional power which we discussed about in a previous post. the movement is a way for watchmakers to look a little deeper into the ongoing research in watch power. for example, in the lange 31 the key winding mechanism is larger than usual for luxury watches, but the size is a technology in itself because men’s mont blanc fewer revolutions are needed and power can be built up a lot faster than a smaller key winder.
another innovative and patented feature of the watch includes a outsized date indicator. after the 31st day of each month it automatically switches to the 1st date of the following month and it’s extremely legible; really large for great reading.
this watch deserves a lot more re panerai watches cognition if you ask me, it has been the center of attention for a while, but 31 days of power reserve is an amazing technological feat in watchmaking. other specifications include a calibre l034.1 movement, power reserve indicator, outsized date, sapphire crystal glass and caseback, crocodile strap, solid silver dial, and constant force escapement for controlled torque delivery.
