Stepping up in the same colour and case shape
Ulysse Nardin built its reputation on marine chronometers — timekeepers that navigators trusted at sea — and the Diver collection carries that lineage forward into something worn on the wrist rather than bolted to a ship's chart table. This reference fits that tradition honestly: a concave unidirectional bezel, a sandblasted blue dial that stays legible rather than decorative, and an anchor engraved into the solid caseback as a quiet acknowledgement of where the brand comes from. The UN-816 beneath that caseback is built on a Sellita SW300 architecture, but Ulysse Nardin has replaced the escapement components — anchor and escape wheel both — with silicon parts. Silicon runs without lubrication, resists magnetism, and does not wear the same way metal does; over years of ownership that matters more than any headline specification. At 42mm on a fabric strap the watch sits lightly, and the blue textile keeps the whole thing from feeling heavy-handed for daily use.

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?
Yes. At 300m it is rated for swimming, snorkelling and recreational diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes 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 comparedHow 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.
