With its latest technological enrichment, the LANGE 1 MOONPHASE corresponds precisely to the LANGE 1, the globally acclaimed pièce de résistance of the Glashütte workshops, which in the meantime has received countless awards. The enhanced, manually wound Calibre L901.5 movement, consisting of 398 individual parts, stands out with a host of the typical hallmarks of Lange quality, among them:
- rigid Glashütte three-quarter plate made of cross-laminated German silver
- twin mainspring barrels for more than three days' power reserve
- patented Lange outsize date
- hand-engraved balance cock with whiplash precision index adjuster and a shock-resistant screw balance timed to 21,600 semi-oscillations per hour
- stop seconds
- 54 jewels, of which nine in screwed gold chatons
- manually blued steel screws
- manually bevelled and polished plate edges
- plates and bridges damascened and solarised with Glashütte ribbing
- endstone set in a gold chaton on the separate escape wheel cock, carried by a black polished steel plate true to tradition.
The LANGE 1 MOONPHASE is available in three case styles and with hand-stitched crocodile straps and the sturdy Lange prong buckle: yellow gold (Ref. 109.021), pink gold (Ref. 109.032), and platinum (Ref. 109.025). Precious metal bracelets and clasps are available on request as well. The heavy three-part cases with sapphire-crystal glasses and casebacks feature a push-piece at 10 o'clock for fast adjustments of the Lange outsize date and a recessed corrector between 7 and 8 o'clock for the moon-phase display. The ergonomic crown with the embossed Lange signature communicates perfection down to the last detail. It winds the movement and sets the time. The neatly arranged displays on the asymmetric, tiered solid-silver dial interact with celestial harmony to tell the hours, minutes, and seconds, to indicate the power reserve, to show the outsize date in the smart twin aperture, and now to faithfully track the orbit of the moon which is framed by the seconds scale. The LANGE 1 MOONPHASE salutes the night with its luminous hour, minute, and power-reserve hands as well as its glowing hour markers. These features and the precision-crafted solid-silver dial with the subtly accented chapter ring and minute scale emphasise the winning personality of this new LANGE 1 which will delight connoisseurs of benchmark horology with its aesthetic and technical refinements. In this particular case, the asymmetric dial architecture designed in 1990 for the first Lange timepiece of the revival has proved to be quite providential: the position of the moon-phase display on the dial relative to the hour and minute scale is congruent with the position of the moon relative to the earth.
