Piaget – Reference 612104: The Cosmic Lava Lamp


If a lava lamp were a watch, it would be this Piaget. Born in the space-age dreamscape of the 1970s, the reference 612104 is pure retro-futuristic mysticism. 

With its yin-yang, teardrop-shaped green and gold enamel dials, it doesn’t just tell time—it transports you straight into a teenager’s room circa 1975, where blacklight posters glow and the cosmos feels just within reach.

 But this is more than just an aesthetic trip. 


The dual-timezone design isn’t a gimmick—it’s a portal. The dials resemble alien runes, a cryptic message of balance and harmony etched for travelers who navigate more than just Earthly coordinates. It’s a watch for those who exist on multiple planes of reality, for those who know time isn’t a constraint but a choice.


Powering this cosmic artifact are two Piaget 6P1 calibers—one for Earth’s time, the other for whatever distant planet calls you home.
