Description
This super clone Seamaster references the 231.10.42.21.02.005 and presents the Aqua Terra 150m in a 42mm stainless steel case with a silver-toned dial that catches light across its applied indices. The 231 generation established the Seamaster Aqua Terra as a legitimate contender in the luxury sport watch segment, and this particular reference demonstrates precisely why that reputation developed. The combination of a light dial, three-dimensional applied markers, and a polished bezel creates a watch that reads as both dressy and capable depending on context and pairing.

The .02.005 designation in the reference number indicates the specific dial and hand configuration within the broader 231.10.42 family. Omega uses this granular numbering system to differentiate dozens of variants that share the same case architecture but differ in dial color, hand finish, or surface treatment details.
Inside the Movement
The automatic caliber in the 231 series uses a free-sprung balance paired with a co-axial escapement for improved rate stability. This combination aims for better long-term accuracy compared to conventional lever escapement designs found in most mechanical watches. The date mechanism snaps over cleanly at midnight rather than slowly crawling, and the seconds hand can be stopped via crown pull for precise time synchronization. For a different take on the Omega sport watch format, see the Aqua Terra World Time 220.10.43 reference, which adds a 24-zone world-time ring to a similar case platform. Both are accessible from the Seamaster collection page for direct comparison.
What Sets It Apart
The 42mm 231 series with a silver dial occupies a specific spot in the Seamaster hierarchy: large enough for confident wrist presence, light enough in dial color to function as a dress watch alternative, and water-resistant enough for active daily use. The replica omega seamaster remains one of the most searched-for sport watch categories because the original design accomplishes so much versatility in a single package. This 42mm Aqua Terra captures that adaptable character in the previous-generation case shape that many collectors still prefer over the newer 220 series for its smoother contours.
