Ulysse Nardin Maxi Marine Chronometer Ref. 263-67/40

Classic Stainless Steel Marine Chronometer | Automatic COSC Movement | White Dial | Power Reserve Indicator

Overview

The Ulysse Nardin Maxi Marine Chronometer Ref. 263-67/40 represents the brand’s long-standing connection to marine chronometry, combining a robust stainless-steel construction with a precise automatic chronometer movement.

Featuring a 43 mm stainless-steel case, a white dial with Roman numerals, blue hands, and a black alligator leather strap, the watch offers a distinctive combination of sporty functionality and traditional Swiss watchmaking.

The dial provides a highly practical layout with a power-reserve indicator at 12 o’clock, small seconds and a date display at 6 o’clock. The watch is powered by Ulysse Nardin’s UN-26 automatic calibre, which is COSC-certified as a chronometer and provides approximately 42 hours of power reserve.

Historical Context

Ulysse Nardin has a particularly strong heritage in marine chronometry. Founded in Le Locle in 1846, the manufacture became internationally recognised for producing highly precise marine chronometers used for navigation.

The Maxi Marine Chronometer collection brings this maritime heritage into a contemporary wristwatch format. Reference 263-67/40 combines the traditional characteristics of a marine chronometer with a larger 43 mm stainless-steel case, modern water resistance, and an automatic COSC-certified movement.

The model's design is defined by its white dial, Roman numeral hour markers, blued hands, and characteristic power-reserve indicator. A transparent caseback allows the UN-26 movement to be viewed.
