Editor's Notes

Montblanc's '1858 Geosphere' watches pay tribute to the adventuring spirit of mountaineers and were released to mark the 160th anniversary of the storied watchmaker Minerva. Integrated with dual time zones, this limited edition timepiece is illustrated with northern and southern hemispheres on the dial, and red dots marking the peaks of the Seven Summits Challenge, while the case back has a special depiction of the Gobi Desert and compass engraving. The automatic calibre is informed by movements from the 1920s, and the smoked dial, bronze case and hand-sewn leather strap have a bygone quality of archival chronographs.

We offer a two-year warranty for all working parts and manufacturing faults for luxury watches. For more information, contact one of our experts by emailing
