NOMOS gives you a city-based worldtime display in a notably thinner case; TUDOR keeps a reference-time hand on home time while letting you jump the local hour forward or backward. Choose by how you travel and wear a watch: the NOMOS emphasizes a slim profile and city selection, while the TUDOR offers a more direct local-time adjustment, a higher water-resistance rating and a longer stated power reserve.
How their time-zone displays work
The central difference is not simply how many time zones each watch can show; it is how you interact with it when you travel. NOMOS uses a city ring and 24-hour register, while TUDOR uses a conventional traveler-GMT arrangement with separate reference and local-hour indications.

NOMOS: select a city, then synchronize the display
The Club Sport neomatik Worldtimer uses the integrated DUW 3202 movement. NOMOS’s instructions are a three-step setup: choose a city with the pusher, synchronize the displays using the supplied setting pin and case corrector, and set the time with the crown. The city ring makes the selected time zone part of the display rather than requiring you to interpret a separate rotating 24-hour bezel. See the NOMOS collection page for the setting instructions and movement overview.
TUDOR: keep reference time while jumping local time
The Black Bay Pro pairs a fixed 24-hour bezel with a yellow 24-hour reference-time hand. When changing time zones, the local-hour hand jumps independently in either direction, and the date follows local-time changes. That arrangement is useful if you want to retain a clear home- or reference-time indication while adjusting the local hour. TUDOR describes the operation on its Black Bay Pro family page.

Case, water resistance and movement specifications
The published dimensions point to different priorities. NOMOS is thinner by a substantial margin, while the cited TUDOR reference is rated to a higher water-resistance depth and has a longer manufacturer-stated reserve.
| Specification | NOMOS Club Sport neomatik Worldtimer | TUDOR Black Bay Pro |
|---|---|---|
| Case diameter | 40 mm, per NOMOS’s 2025 launch material | 39 mm, for reference M79470-0004 |
| Case thickness | 9.9 mm, per NOMOS’s 2025 launch material | 14.6 mm, for reference M79470-0004 |
| Water resistance | 10 atm / 100 m, per NOMOS’s 2025 launch material | 200 m, for reference M79470-0004 |
| Movement and stated reserve | DUW 3202, integrated worldtime caliber; 42 hours, per NOMOS’s 2025 launch material | MT5652, COSC-certified self-winding GMT; approximately 70 hours, per TUDOR |
These are manufacturer specifications, not independent tests of accuracy, endurance or real-world water performance. The 200 m rating is higher on paper, but it does not by itself establish a particular dive certification. The TUDOR figures above are specific to the opaline M79470-0004 product page; case measurements and details can vary by reference. NOMOS’s dated figures come from its April 1, 2025 launch release, and TUDOR’s reference-specific specifications are on the M79470-0004 product page.
The 40 mm versus 39 mm diameter difference alone cannot predict wrist fit. Thickness is the more conspicuous published distinction: the NOMOS is 9.9 mm high, compared with 14.6 mm for the cited TUDOR. Trying each on is the most useful way to judge how those dimensions, case shape and strap or bracelet feel on your wrist.

As displayed on the manufacturers’ U.S. pages checked October 7, 2026, the prices differ by reference and configuration. These are manufacturer price displays, not a survey of retailer or secondary-market prices, and may change.
| Watch and configuration | Displayed U.S. price | Source and qualification |
|---|---|---|
| NOMOS references 790 and 791 | $5,370 | NOMOS U.S. collection page, checked October 7, 2026 |
| NOMOS reference 792 | $5,580 | NOMOS U.S. collection page, checked October 7, 2026 |
| TUDOR Black Bay Pro, opaline and some bracelet variants | $5,075 | TUDOR U.S. pages, checked October 7, 2026; configuration-dependent suggested retail price |
| TUDOR Black Bay Pro, certain fabric or hybrid-strap variants | $4,725 | TUDOR U.S. pages, checked October 7, 2026; configuration-dependent suggested retail price |
The NOMOS collection page shows blue 790, silver 791, silver 792 and dark 793, among other editions. TUDOR lists black- and opaline-dial versions with bracelet, fabric or hybrid strap configurations. Because the displayed prices do not correspond to one uniform strap or bracelet configuration, compare the exact reference and included fitting before treating one figure as a like-for-like price. Current NOMOS listings are on the U.S. collection page, and TUDOR configurations are on its family page.
Which one should you choose?
Choose the NOMOS if a thinner worldtimer suits your routine
- You prefer a city-based display and the NOMOS pusher-and-corrector setting sequence.
- A 9.9 mm published case height matters more to you than the TUDOR’s higher water-resistance rating or longer reserve.
- You want the NOMOS design and are comparing its exact reference and price against a specific TUDOR configuration.
Choose the TUDOR if you want a jumping local hour and a home-time reference
- You want to adjust local time in either direction while retaining the yellow reference-time hand.
- The cited M79470-0004’s 200 m rating is a more useful specification for your intended wear than NOMOS’s 10 atm rating.
- You value the approximately 70-hour stated reserve over the NOMOS movement’s stated 42 hours.
These are different solutions, not interchangeable executions of one interface. NOMOS’s Ines Hatzmannsberger described its launch as “a reimagined world time watch for the everyday life of a global generation” in the 2025 Watches and Wonders transcript; that is the manufacturer’s positioning, not an independent performance assessment.
