OMEGA introduced three black-lacquer-dial Seamaster Aqua Terra 150M watches in June 2024: 34 mm, 38 mm and 41 mm models. They share a glossy, smooth black dial, but differ in dial layout, case dimensions and movement. The 34 mm and 38 mm use calibre 8800; the 41 mm uses calibre 8900.
What distinguishes this black-dial trio?
The defining feature is the smooth, glossy black lacquered or varnished dial. That sets these references apart from earlier black-dial Aqua Terra models discussed in the launch coverage, which used the collection’s teak-inspired horizontal stripes. OMEGA described the June 2024 range as a black varnished-dial version of the Aqua Terra. Fratello Watches’ launch report and OMEGA’s announcement show how the design changes across the sizes.

How the three references compare
| Case size | Reference | Dial details | Movement and reported power reserve | Reported dimensions |
|---|---|---|---|---|
| 34 mm | 220.10.34.20.01.001 | Round date window, sailboat-shaped applied indexes, no outer minute track | Calibre 8800; 55 hours, as reported by Fratello Watches in 2024 | 34 × 40.5 × 12 mm; 16 mm lug width |
| 38 mm | 220.10.38.20.01.004 | Trapezoidal date window, sharp triangular indexes, outer minute track | Calibre 8800; 55 hours, as reported by Fratello Watches in 2024 | 38 × 45.1 × 12.3 mm; 19 mm lug width |
| 41 mm | 220.10.41.21.01.002 | Trapezoidal date window, sharp triangular indexes, outer minute track | Calibre 8900; 60 hours, as reported by Fratello Watches in 2024 | 41 × 48 × 13.4 mm; 20 mm lug width |
Dimensions are diameter × lug-to-lug × thickness, and all three sets of measurements are reported by Fratello Watches rather than independently measured here. OMEGA identifies the movements as Co-Axial Master Chronometer calibres certified by METAS. The brand’s specifications also give each watch 150 m (500 ft) water resistance and a five-year warranty. OMEGA’s announcement provides the range’s official design and specification details; Fratello’s report supplies the case measurements and power-reserve figures.
Choosing between the 34 mm, 38 mm and 41 mm
34 mm: the distinct dial layout
The 34 mm reference is not simply a smaller version of the other two. It has a round date window, sailboat-shaped applied markers and no outer minute track. Its reported lug-to-lug length is 40.5 mm, with a 16 mm lug width.

#1 Best Overall
- Model 220.12.38.20.03.001
38 mm: the smaller of the two matching layouts
The 38 mm shares the larger models’ trapezoidal date window, triangular indexes and outer minute track. Its reported dimensions are 38 mm across and 45.1 mm lug-to-lug, with a 12.3 mm thickness and 19 mm lug width.
41 mm: the different movement
The 41 mm also follows the larger dial layout, but pairs it with calibre 8900 rather than calibre 8800. Fratello reports a 60-hour power reserve for calibre 8900, compared with 55 hours for calibre 8800. Its reported lug-to-lug length is 48 mm and thickness is 13.4 mm.

Those measurements can help narrow a fit preference, but they cannot establish which watch will suit a particular wrist. The available launch information does not provide wearer testing or wrist measurements.
Bracelet and everyday specifications
Fratello’s 2024 launch coverage describes a steel bracelet with a butterfly deployant clasp and tool-free comfort adjustment. OMEGA specifies 150 m water resistance and a five-year warranty for the range. These are manufacturer-stated specifications, not independent test results.
Rank #3
- Omega Seamaster Aqua Terra Automatic Men's Watch 220.10.41.21.01.001
Launch price and later reference
Fratello reported a launch price of €7,300 including VAT for each of the three watches in its June 21, 2024 coverage. That is a historical reported price, not a verified current price or a figure that can be assumed to apply in every market. OMEGA’s November 3, 2025 seasonal feature still identified the 41 mm reference 220.10.41.21.01.002, but that mention does not establish current stock or the status of the 34 mm and 38 mm versions. OMEGA’s 2025 feature names the 41 mm watch.
