Whilst I was on the plane today 
I like some of what I see from the press releases so far, especially those with maps on the dial - the 4810 Orbis Terrarum looks like it will repeat the success of the Heritage Spirit Orbis Terrarum. A tad bigger at 43mm for the 4810 Orbis Terrarum compared to the 41mm Heritage Spirit Orbis Terrarum but with a more colorful worldtime dial with shades of green and orange/ yellow for the daytime indicator.
I believe we will see some live pictures from the other PuristSPro Moderators who are in SIHH now so stay tuned everyone! 
Cheers
Robin
