Stepping up in the same colour and case shape
Ulysse Nardin's Diver line occupies an interesting position: a house built on marine chronometers and precision instruments for the sea, producing a contemporary diver that connects that heritage to daily wear. This reference pairs that lineage with a Milanese mesh bracelet, which is an unusual choice for a 300-metre-rated tool watch and one that shifts the character of the piece considerably. At 12.2mm thick, it sits notably flat for its depth rating — most watches certified to this level carry more bulk than this, and the consequence is that it disappears under a shirt cuff in a way its competitors rarely manage. The UN-816 runs silicon components in the regulating organ, meaning no lubrication is required there and the rate should stay stable for longer between services than a conventionally finished movement. The matte black dial keeps reflections off the surface and lets the rhodium-plated indices and Super-LumiNova do their work cleanly, whether in low light above water or below it. The mesh bracelet, beyond looking unlike anything else at this depth rating, adjusts at the clasp without tools — a detail that matters more than it sounds when the watch moves between a bare wrist and a wetsuit sleeve.

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.
What size strap does it take?
21mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 47.5mm, which suits wrists from roughly 16.5cm (6½ inches) upward.
Lug-to-lug decides fit more than case diameter does.
