Introduced in 2009, the A. Lange & Söhne ZEITWERK

immediately made its mark with a mechanical jumping numerals display. The

Zeitwerk family now welcomes a new addition, the third with an acoustic

indication. This new model sounds the time on two pitches, one for the full

hour and one for ten-minute intervals. The two polished steel hammers, visible

on the dial side, are decorated with tremblage engraving. The left hammer

strikes a low note to indicate each full hour while the right hammer sounds a

high note every ten minutes. This striking function can be silenced by means of

the pusher at 4 o'clock. Proposed as a 100-piece limited edition, the case is

crafted from A. Lange & Söhne's proprietary honey gold.
