Hi,
The reverso Grande Sun Moon is a beautifully designed watch ( I own one). It's featured in the 2007 catalogue.
I think the reason why it is not getting much attention because it was released at the same time with the JLCSquadra series. The Squadar series has more marketing (since being the first) and because of the squadras' bigger dimension design, it appeals especially popular with the men or ladies who prefer a big watch. The entry Squadara Hometime is also a few grand cheaper then the Sun Moon.
IMO Reverso Grande Sun Moon has all the appeals (it is especially beautiful to say during daytime) to be a awesome and classic watch but it was somehow overshadowed by other new releases in the JLC sea of reverso series. Somehow you will always find them in the AD stock but the squadra and I believe this will stay on. Imagine Sun Moon is on a squadra case....what would happen????
