Montblanc extended its 1858 Geosphere collection with a new titanium variation for 2020.

First released in 2018 — with a black sunburst dial and a black ceramic bezel insert and in stainless steel or limited edition bronze case — the Geosphere 1858 is now available with a blue gradient dial, a blue ceramic bezel insert, and in a grade 5 titanium case.

Grade 5 titanium is lighter than steel or bronze and even compared to grade 2 titanium, it’s more resistant to scratches. Although lighter, the case dimensions are the same as before, at 42 mm x 12.8 mm.

The movement, caliber MB 29.25, is not a manufacture movement (is based on Sellita caliber SW300-1) but does have an in-house complication added on for the world time functionality. The 4Hz movement is automatic, has 26 jewels, and a 42-hour power reserve.

The main complication, developed by the Montblanc watchmakers in Villeret, are the two domed globes, one for the northern hemisphere and the other for the southern hemisphere, turning in opposite directions, which complete a full rotation in 24 hours. Both have divisions showing 24 time zones, along with coordinating individual day/night indications.

2020 Montblanc 1858 Geosphere

As before, in addition to the useful world time complication, the 1858 Geosphere comes with a bi-directional rotating bezel that features cardinal bearings and can be used as a compass, in conjunction with the hour hand.

Further, the compass bezel, dual-time globes, second-time zone indication, and main time are all lit by luminous paint. The paint is white to match the blue color scheme, as opposed to cream for the original Geosphere 1858s that debuted in 2018.

A second-time zone indication sits at 9 o’clock, and the date is indicated opposite that at 3 o’clock (via a blue color-matched date wheel visible through a rectangular aperture).

The 1858 Geosphere comes with a domed sapphire crystal, a flat ridged crown in titanium — with the black and white Montblanc emblem inlaid in the center — and is water-resistant to 100 meters.

For 2020, the Montblanc 1858 Geosphere is available with a blue Sfumato calfskin leather strap for with white two-stitch threading for $5,800 or a beads-of-rice metal bracelet for $6,200, both at 22 mm wide at the lug end. (Ref. Ref. MB125565)
