Note to collectors: this watch features a Martin Braun proprietary movement, not a modified ETA as in the past. After joining forces with Franck Muller, MB started producing in-house movements, making this an even more unique timepiece.
"...If this watch were to be kept wound for 122 and a half years, its moon phase display would deviate only by one day. This is just one of the elements that differentiates it from a conventional moon phase display, meaning that this timepiece can be worn for close to three generations before its realistic moon needs to be corrected.
The setting of conventional moon phase displays generally takes place incrementally, meaning that the disk is moved in little steps, making an absolutely precise setting only nominally possible. This is not the case with the Selene. Setting is done by a corrector located in the case band at 8 o’clock. The corrector guarantees that the disk that eclipses the large moon on the dial can be rotated gently and evenly. This also means that the moon phase display can be set to the minute. If, for example, full moon occurs at precisely 10:05 pm, then the disk can be moved via the corrector at exactly 10:05 so that absolutely no eclipsing of the moon is visible and the entire moon beams up at its wearer. The Selene is the first and only watch in the world to make this possible.
This realistic moon display is something Martin Braun and his team achieved creating after numerous attempts to permanently capture a photorealistic moon in glass. A disk with two dark circles revolves underneath this transparent moon and eclipse it. Thus, the shadow of the moon is clearly to be seen, and even at new moon it is there and visible. This design is completely new and replaces the two semi-circular cutaways used in conventional displays." (from Martin Braun website). CS053813.
