On day one of SalonQP, the United Kingdom’s largest watch fair, Montblanc has unveiled a new version of the Orbis Terrarum that’s extremely limited in production and quite patriotic (if you’re British, of course). The company has decided to make just five pieces based on the 4810 Orbis Terrarum (not to be confused with the earlier Spirit Orbis Terrarum), with a small twist: a Union Jack flag signaling the daytime hours on the day/night disc indicator.
