Compare the older version of the villeret moonphase to the new version through the above link. I prefer the older version. As HEPennypacker said, I dont know how I feel about that curved date hand, and I think the roman numerals, the logo placement, and the moon face are all superior on the previous version
I looked at this watch HARD before the MUT Moon was announced, then switched my loyalty. I've tried on both (that is to say the MUT Moon and the older Villeret Moon. Ive never seen the new BP VM). The BP is smaller at 38mm. It's a more classic look (in terms of morning suits and monacles) whereas the JLC is going for a more modern stripped down minimalism IMO. I've read a few complaints about the JLC in this regard, that it lacks a full calendar complication up top like the reverso calendar or the BP VM but as i said I think they were trying to strip things down.
