Lambda features a complication: the power reserve indicator. It sweeps an arc across the dial and tracks 84 hours, or three-and-a-half days, accurate to the hour. The four needle-thin hands give this watch model a graceful elegance—with fine features reminiscent of a kinetic sculpture.
The polished case of the watch frames the dial with a slender bezel, while the transition from the side to the back of the case is a radiodrome; that is, a curve with a shrinking radius. The lugs reflect the curved form of the case as well.
