A 38mm hand-wound Swiss watch that looks like a purist's dress watch until you wind it. The domed eggshell matte dial is quietly luminous, warm against polished and brushed 316L stainless steel. Wind the crown and the sapphire caseback reveals a fully mechanical animated penguin automaton driven by the same motion that powers the Soprod P054 movement. Discreet, irreverent, and rooted in 18th-century Swiss automata tradition. 10 ATM water resistance. Swiss made.
