NOMOS Lambda Roségold

Here's the info, straight from the good folks in Glashutte -


Lambda Roségold: In mathematics, the Greek letter Lambda is a symbol for intrinsic values. At NOMOS Glashütte, it is the name of a highly precise instrument, constructed according to the rules of science and those of the watchmaking craft in the NOMOS workshops. For all this logic and reason, it remains a timepiece that calls forth the highest emotions. In white gold or, as shown here, a tick warmer in rose gold: a fine choice between two watches, both exempli- fying handicraft of the very best kind.

DUW 1001: Lambda’s caliber differentiates it in many ways from all other (equally fine) watches. The rubies of the movement, in which the staffs of the wheels turn, are held in polished gold chatons (18 karat), which are in turn screwed to the three-quarter plate with two or three blued screws. The edges of all the cocks and plates are angled and polished by hand. And the three-quarter plate is decorated with a stripe polish that catches the light beautifully, which is only to be found in this particular style at NOMOS Glashütte: the fine sunbeam polishing. Twin mainspring barrels ensure an extra power reserve—this extremely precise watch only requires winding twice a week. This is displayed on the dial side in the most aesthetically pleasing way: DUW 1001 has a 84-hour power reserve indicator.
