Yes the Japan LE edition is a very nice one. Another LE that I recall correctly but I can’t find by googling would be the brown dial version done for “Hausman” (spelling) in Italy. I could have sworn I saw the press release years ago for this limited edition for the Italian retailer.
I can’t speak for service intervals but I did just get a 16710 back from service. I’m in USA and dropped off my watch at the AD on April 5th, they sent to Rolex service center (assuming Dallas RSC like previous watches I’ve had serviced) and the AD called yesterday with the watch ready to pick up. B
