Which Black Lacquer Aqua Terra is this?
This article covers the 41 mm bracelet model, reference 220.10.41.21.01.002, as identified on OMEGA’s official Japan product page. The page is for the Japanese market; its local pricing should not be read as a US or worldwide price.
OMEGA announced its black-dial Aqua Terra range on June 21, 2024, in three sizes: 41 mm, 38 mm and 34 mm. The name alone can therefore refer to a family of watches rather than this exact reference. Check the reference number when comparing a listing or another size.

What distinguishes the dial and case?
The defining appearance is a black varnished dial finished with lacquer. On this 41 mm version, the date window sits at 6 o’clock; the dial also uses triangular indexes and an outer minute track, as described in OMEGA’s 2024 black-dial Aqua Terra announcement.
The listed 48.00 mm lug-to-lug measurement and 13.40 mm thickness are useful alongside the 41 mm diameter when judging wrist fit. The bracelet is stainless steel, and the 20 mm lug width is the relevant dimension to check when assessing compatible straps.

How does it compare with the 38 mm and 34 mm black-dial models?
OMEGA’s 2024 launch announcement describes different dial layouts and calibres across the three sizes. The 41 mm model has the trapezoidal date window, triangular indexes and outer minute track. The 38 mm model also has a trapezoidal date window, triangular indexes and minute track; the 34 mm version instead has a round date window, sailboat-shaped indexes and no minute track.
| Size | Dial details in OMEGA’s 2024 announcement | Calibre stated in the announcement |
|---|---|---|
| 41 mm | Trapezoidal date window, triangular indexes, outer minute track | 8900 |
| 38 mm | Trapezoidal date window, triangular indexes, outer minute track | 8800 |
| 34 mm | Round date window, sailboat-shaped indexes, no minute track | 8800 |
OMEGA described all three sizes as Master Chronometer certified. The 60-hour power reserve in the specifications above belongs to the 41 mm calibre 8900 reference; the launch announcement does not state a power reserve for the 38 mm or 34 mm models.
