Nomos Worldtimer Dark adds lume to the city ring and home dial

Nomos Glashütte has launched the Club Sport Neomatik Worldtimer Dark, a black-dial version of its slim world timer that joins the permanent collection. The headline change is lume: the city ring and the home-time subdial now glow, not just the hands, numerals and indexes as on earlier versions.

The dial is glossy black, finished in what Nomos calls enamel, though it is not grand feu enamel. Hands, hour markers, numerals, the 24-hour subdial and the city ring are printed in warm off-white and coated in blue-emitting Super-LumiNova. After dark, the whole world-time display lights up.

The Dark arrives at the annual Nomos Forum. Last year the brand used the same event for the limited Night Navigation series, three references with sunburst black dials and colorful accents. This year it keeps the lights down and makes the black dial a core reference, number 793 SB.

What the Worldtimer Dark costs

Prices start at €3,920, $5,140 or £3,920 with an all-steel caseback and a textile strap. The version with a display caseback and steel bracelet costs €4,400, $5,760 or £4,400. The bracelet price matches earlier Club Sport Worldtimer models, so the extra lume comes at no added cost.

A solid caseback and several textile or leather straps are offered as options. The bracelet is a three-row Oyster-style design with brushed outer links and polished center links. Quick-release spring bars let owners swap it for one of the brand's textile straps.

The bracelet has two weak points. Its polished clasp scratches easily and it still has no micro-adjustment system. Both would improve daily wear, and neither has changed with this launch. The dial and lume are where the update is.

Case, movement and how it works

The case is unchanged: stainless steel, 40mm across, 9.9mm thick and 48mm lug to lug. It has a screw-down crown, a screwed caseback and 100 meters of water resistance. The lugs are among the shortest on any Nomos, so the watch wears compactly.

Inside is the in-house automatic caliber DUW 3202, which runs at 21,600 vph with 37 jewels and a 42-hour power reserve. It measures 31mm across and 4.8mm thick. It has the brand's blue-spring swing system escapement, developed with help from the university in Glashütte, and is adjusted in six positions.

Local time is on the central hands, with small seconds at 6 o'clock. A pusher at 2 o'clock, above the screw-down crown, advances the hour hand in one-hour steps and turns the city ring through the 24 time zones, while home time is on a 24-hour subdial at 3 o'clock.

That subdial has a two-color ring as a day-night indicator, outlined with blue and red ribbons inspired by Pan Am. The time offsets around the dial's edge are red, which gives the watch a sportier character. It is closer to a GMT with a city ring than a classic worldtimer.

The movement is decorated with thin stripes, blued screws and a classic three-quarter plate, visible through the sapphire caseback on the bracelet version. Nomos has made watches in Glashütte since its creation in 1990, and the finish shows the standard of that workshop.

Where the Club Sport Worldtimer came from

The Club Sport Neomatik Worldtimer debuted at Watches and Wonders Geneva in 2025 in brushed silver and blue. It was widely praised for its design, function and price, and became a commercial winner for Nomos. Several limited editions followed, including six colorful models, the Reverie and Roam editions, and the Radiant White.

The Dark is that white watch's opposite, and it pushes the Night Navigation idea further with lume. One commentator likens it to the Nomos × Fratello Weltzeit watches and their two-tone dials, and suggests the dark look may suit smaller wrists.

Nomos is known for Bauhaus-influenced design and German watchmaking at a fair price. In our ranking of the best luxury watch brands, NOMOS Glashütte is one of three names, with Tudor and Grand Seiko, that give the most watch for the money.

At $5,760 on the bracelet, the Dark stays at the price of earlier Club Sport Worldtimer models, while many rivals lean on price increases to grow sales. The new lume is the one thing added, and Nomos adds it for free.
