Just found a pic of the 2008 Japan market LE in a local magazine. There wasn't much info on it but the short description said that the watch had a diameter of 42mm (I hope it was just a typing error). The case and dial aesthetics point to the Traditionelle automatic but I am not sure if the skeletonized movement (with geneva seal) is the in-house auto. It could very well be (and looks like) the already existing skeletonized cal. 1120 movement in Traditionelle-style clothing. Its limited to 40pcs.
Just like the Malte power reserve, and the Traditionelle automatic that had their roots in Japan LE's, this could be another design study that could make it into regular production.
I'll keep a lookout for it and make another post as soon as I catch it in the metal.
