T3 The Leo


The T3 is Zeroo’s first automatic tourbillon and the only watch in the collection presented on a stainless steel bracelet. Its open works design adds an architectural aesthetic that is both industrial and refined, making the T3 ideal for both dress and casual wear. Elegant and sporty, the Leo offers a modern take on a classic style.


Please note that T series watches are manual, hand-wound timepieces. It is important to never overwind your watch. We recommend up to twenty winds every other day.
