The 42mm stainless steel case combines brushed and polished surfaces, sitting above a fixed black-coated bezel. The sunray-brushed black dial carries applied indices and Roman numerals, with an oversized double-window date display at two o'clock and a small seconds sub-dial at six. The home time indication sits at nine, adjusted via pushers on the left flank. Hands and markers are filled with luminous material. The self-winding UN-24 calibre runs at 4 Hz with a 42-hour power reserve. A black rubber strap with pin buckle completes the watch.

Learn more about Ulysse Nardin

Leonard Ulysse Nardin founded his workshop in Le Locle in 1846 and specialised in marine chronometers — the instruments ships used to determine longitude, where an error of seconds meant an error of miles.

The house became one of the two or three most important chronometer makers in the world. More than fifty navies used Ulysse Nardin instruments, and the company holds an extraordinary record at observatory trials: over four thousand certificates and dozens of gold medals, more precision awards than any other manufacturer.

Its modern era began in 1983 when Rolf Schnyder bought the failing company and partnered with Ludwig Oechslin, a scientist and horological historian. The results were the Astrolabium Galileo Galilei of 1985, which displays the positions of sun, moon, and stars and entered the Guinness records as the most functional wristwatch, followed by the Planetarium and Tellurium — together the Trilogy of Time.

Oechslin also designed the Freak of 2001, arguably the most radical wristwatch of the modern era: no dial, no hands, no crown. The entire movement rotates to indicate the time, and it was the first watch to use silicon components in the escapement, a material now standard across the industry.

The Marine collection continues the chronometer heritage. Kering acquired the brand in 2014.

Frequently asked questions, and things you should know about this watch

Can I swim with it?

Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.

Water resistance explained

Will the glass scratch?

Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.

Sapphire, mineral and acrylic compared

Does it need a battery?

No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.

Quartz, automatic and solar compared

How long does it run for when it's not worn?

About 42 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
