Long before the wristwatch became an expression of personal style, Ulysse Nardin was building precision instruments for those who navigated the world's oceans.
Founded in Le Locle, Switzerland, in 1846, the manufacture established its reputation through marine chronometers—highly accurate timekeepers essential to navigation before the arrival of modern electronic systems.
The Maxi Marine Diver translates that heritage into a contemporary sports watch. Its oversized case, wave-pattern dial and prominent power-reserve indicator evoke the functional character of traditional marine instruments.
Reference 263-90 combines a lightweight titanium case with an automatic chronometer movement, a rotating dive bezel and 200-meter water resistance. Its design is unmistakably nautical, yet its decorative dial and distinctive proportions give it a character beyond that of a conventional dive watch.
