A. Lange & Sohne 140.029 Box & Cert Dated NOV 2011.  A true revolution in time telling! While most watches tell time using rotating hands to indicate the minute & hours, this watch actually displays the time via a mechanically operated fully digital numeric readout. Jump hours & mechanical digital watches are not new, they have been around for decades, however what Lange & Sohne has developed is the first digital-readout display watch that has the hours & minutes apertures lined up horizontally, in a natural reading format. In addition, the hours & minute numbers are displayed in a large format making for an extremely legible & easy read. Polished 18K white gold case with fine satin finished case band (edge). This watch features a black dial. The movement bridge protrudes through the dial & is made of untreated German Silver with a fine brushed finish. The bridge encompasses the hours, minutes & seconds displays. As the bridge is part of the movement, the dial is lowered to surround the bridge, thus reducing the overall case thickness. Jumping hour & minutes in a digital display of Arabic Numerals. Hour & minute windows display with tapered edged window frames. The tapered frame eliminates shadows, allowing for a clean & legible view of the current time. Small seconds silver sub-dial located at the bottom of the dial. Power reserve (Up/Down) Indicator located at the top of the dial bringing symmetry & balance to the dial. Polished white gold hands for both the seconds & power reserve indicators.

  • Visible on the bridge is a large screw which is used to attach the bridge to the mainplate. A sapphire jewel end-stone. Lange Caliber L043.1, beats at 18,000 vph, contains 66 jewels with an approximate power reserve of 36 hours. Other movement features "Patented Mainspring Barrel" A relatively enormous amount of energy is required to both power the movement & simultaneously advance the three disc's every hour. Thus the necessity for a more powerful mainspring. The mainspring sits in a barrel which in turn rotates the opposite way as as the mainspring relaxes, thus keeping a higher level of energy transferring to the movement. Manual Winding   requires a little more effort, as you are winding both the mainspring & the barrel at the same time. "Patented Constant-Force Escapement" provides 2 major innovations, Most escapements deliver the highest level of torque whilst the mainspring is fully wound, yet as the mainspring relaxes the torque weakens. This Escapement delivers a near constant level of torque to the balance across the entire 36 hour period and thus enhances the rate stability of the movement. Provides a switching step for the instantaneous jumps of the minutes & hours with a drop warning, this governs the sudden burst of energy provided to advance the discs. To absorb the excess forces that occur during the sudden advancing and stopping process, the excess energy is dissipated via a fly governor. Most escapements deliver the highest level of torque whilst the mainspring is fully wound, yet as the mainspring relaxes the torque weakens. This Escapement delivers a near constant level of torque to the balance across the entire 36 hour period and thus enhances the rate stability of the movement.
