Montblanc scales Mount Smartwatch with Summit timepiece

German watchmaker Montblanc unveiled its first smartwatch, the Summit, in London on Thursday.

The buckles on all the straps are made from stainless steel.

The watch is available in several different finishes in combinations of black and silver.

The Summit's black calf leather band is the cheapest strap option.

Brown and navy Florentine leather, as well as laser-cut rubber, are more expensive. The priciest option is alligator skin.

The Summit's bezel has a brushed effect caused by tiny microabrasions made in the steel.

The Summit contains sensors that cause the watch face to change as it moves, so that it looks like the light is catching it.

Montblanc based the Summit's faces on traditional designs from its 1858 collection.

Each face has its own complications, which are also Montblanc-branded.

According to Montblanc, the Summit is the first smartwatch to rock a domed sapphire glass face.

This is a pretty distinctive crown, but you can pay more to have it customised.

The Summit will launch globally in May, starting in the UK and Europe. Pricing starts at $890 (£720 or AU$1,160 converted).
