A. Lange & S

[Limestone]

I just found out that A. Lange & S

[gran]

Yes they look absolutley faboulus in a metrosexual way

I think that we are greatly lacking in great A. Lange and S

This is the Lange 31

A watch which runs at a constant rate for 31 whole days without winding? Impossible, say some...Can be done, says the incredible team at Lange. The result - the Lange 31. A very handsome watch, with a simple dial, but hiding an incredibly complex mechanism to crack the 31 day running train.

Not only does the watch run without being wound for 31 whole days, it does so with a constant amplitude...keeping 270 degrees on the balance wheel throughout.

I don't think the large dimensions of the watch are to be feared...these days, might even be considered trendy.

But the reason for this large size is not due to trend...but for a more technical nature...the space required to house the huge mainspring and the clever mechanism to tame the torque.

The watch is powered by 2 mainsprings, each 1.85m in length, and at max power providing 20 N-mm of torque. As a comparison, the twin barrels on the Lange 1 provides 5 N-mm of torque
