Born on Instagram

This collaboration started on Instagram, between Romaric André, alias Seconde/Seconde/, and Guillaume Laidet of Nivada Grenchen. They shared ideas about the best Seconde/Seconde/ touch for the “Pac-Man” Depthmaster, and the jellyfish came straight away.

Seconde/Seconde/, alias Romaric André, is a French artist known among collectors for twisting and customising vintage watches with humour. Discover the full Depthmaster collection.

Jellyfish hands, made in France

The jellyfish hands were made in France, by the last watch-hand manufacturer in the country. They came in five colours: blue, orange, yellow, grey and purple, and only 10 watches were made in each colour.

On the matte black dial, the printed luminous markers and white print keep the time legible, and the hands carry cream Swiss Super-LumiNova.
