Montblanc embeds ancient glacier wood in the Iced Sea’s dial

Montblanc has given its Iced Sea diver an unexpected link to alpine history: real pieces of subfossil wood preserved for millennia within the Mer de Glace glacier. Embedded in a frozen-looking resin dial, the fragments form an organic pattern that makes each watch visually individual.

The Iced Sea Automatic Date 0 Oxygen Limited Edition is housed in a 41mm stainless-steel case with a brown ceramic unidirectional timing bezel. Removing oxygen from the case is intended to reduce the risk of condensation in demanding conditions.

Under the dial, the automatic MB 24.17 calibre offers about 38 hours of power reserve. Its 300-metre water resistance, legible luminous hands and adjustable stainless-steel bracelet keep this unusual material watch firmly within the diving category.

Reference MB137211 was introduced in 2026 in a run of 700 pieces. Montblanc lists a price of €5,900 in Belgium, pairing a genuinely historical natural material with a contemporary technical diver.
