Undercurrent – Natural Blue Agate. The Vincero Undercurrent is built for those who are consistent, unhurried, and effective without announcement. Every dial is cut from genuine blue agate, formed as silica-rich water seeped through volcanic rock over millions of years, creating layered patterns unique to each piece. Each band reflects shifts in pressure and mineral content, making every watch face one-of-a-kind. With a 41mm case, 11.5mm thickness, 22mm strap, and powered by a Citizen Miyota automatic movement, it combines precision and durability. Sapphire-coated crystal, 316L surgical steel, and 10 Atm water resistance ensure longevity. Limited to 500 individually numbered units, this watch embodies patience and timeless style.
