When they’re done right, limited edition watches are great. They offer some exclusivity, membership to a special club, and that feeling of being part of something bigger than yourself. When they’re done badly, limited editions are merely a poorly thought-out logo whacked on a dial. Thankfully this UNICEF limited edition is very much in the former camp. Montblanc has taken one of their coolest models, the Orbis Terrarum, made some super-subtle design tweaks and wrapped it all into a very worthy cause. Who wouldn’t like it?
