Editor's Notes

Montblanc's '1858 Geosphere' watch, now with a suitably glacial blue dial, is an ode to the Seven Summits challenge – "the holy grail of mountaineering adventures" that consists of climbing the highest mountain on each continent. It's been expertly crafted in Switzerland with a MB 29.25 automatic movement that enhances Sellita's SW300 workhorse with an in-house, 'modular' worldtime complication, whose two domed, rotating hemispheres feature 24-hour scales with a day and night indicator - and the seven summits picked out with blue dots.

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
