Jean Marcel includes secret message on its ultra-thin Somnium

Jean Marcel Somnium ultra thin mechanical timepiece.

Jean Marcel, an independent German watchmaker specialising in low-run collectors’ pieces, has introduced an ultra-thin mechanical model named the Somnium Collection.

With a total height of just 6.8mm, the Jean Marcel Somnium is among a new breed of ultra-thin mechanical watches that have the same functionality and reliability as larger pieces.

The 43mm steel watch houses a hand wound JM H05 calibre based on a Swiss made ETA Peseux 7001 movement with glucydur balance to improve precision and reliability.


The movement is visible through a sapphire caseback.

Dials are protected by a non-reflective sapphire crystal on which a mystery Jean Marcel logo appears when it is breathed on.

The Somnium is limited to 300 pieces worldwide priced at €99,500.
