During SIHH, A. Lange & Söhne announced that in honor of the 25th anniversary of the original Lange 1 timepiece, the German brand would be introducing a new limited edition take on the watch every month of 2019 up until October 24, 2019 (10 total watches). January saw the release of the Lange 1 “25th Anniversary” Edition, and today we’re happy to introduce you to the second commemorative model: the Grand Lange 1 Moon Phase “25th Anniversary”.
The Grand Lange 1 Moon Phase is a timepiece that has existed within the greater A. Lange & Söhne collection since 2014. It was released as an extension to the Lange 1 Moon Phase with a larger diameter at 41 mm (2.5 mm larger than its older sibling) and a slightly reorganized dial layout. The moon-phase display is larger than that of the original Lange 1 Moon Phase thanks to its placement in the hour/minute subdial compared to its former placement in the small seconds dial. For proportion’s sake, the big date was increased in size as well by 4 percent.
Just as with the Lange 1 “25th Anniversary” Edition, the new Grand Lange 1 Moon Phase features an argenté-colored dial made of solid silver with blue numerals, indexes, and hands, appropriate for the watch’s “silver jubilee.” The moon-phase disc on the new model is what separates it from any previous release as this is the first time that A. Lange & Söhne has created a moon-phase display with a disc made of solid white gold. Six stars and a number of additional dots are hand-engraved to create the starry night sky surrounding the inlaid golden moon. This construction offers a three-dimensional effect that enhances the poetic complication.
Caliber L095.3 is visible through the sapphire crystal exhibition caseback. As is typical of A. Lange & Söhne, the movement is superlatively finished and twice assembled by hand. The three-quarter plate made of untreated German silver is decorated with Glashütte ribbing and allows a view of the in-house built balance spring. Holding the hairspring in place is a balance cock that has been hand-engraved with the number 25 in the style of Lange’s traditional big date window. The special engraving is surrounded by a floral motif and all engraved recesses are accentuated with a blue coating to tremendous effect.
