Sternglas Marus 2.0

Owners widely praise the Sternglas Marus 2.0 for its well-built, heavy case and excellent bezel action, which is considered superior to some competitors. Reviewers note the refined case and luminous dial markers, while the green dial stands out from other divers. The Seiko NH35A movement offers accuracy ranging from -20/+40 seconds per day. One reviewer desired a slightly larger screw-down crown. Overall, owners and reviewers rate the Sternglas Marus 2.0 highly for its robust build and standout dial at its price point.

From video reviewers

The Seiko NH35 automatic movement is a shared strength. Reviewers did not reach a consensus on any weaknesses.

Seiko Prospex Sea Save the Ocean Special Edition

The Seiko Prospex Sea Save the Ocean Special Edition is widely praised for its visually striking and unique dial designs, often described as a standout feature offering significant aesthetic appeal for the price. Owners and reviewers consistently highlight the attractive blue gradients, wave patterns, and textured finishes that evoke ocean depths. The watch is generally considered comfortable to wear, with a well-proportioned case size and good build quality. Accuracy is reported as around +5 seconds per day by one owner. However, several sources point to the bracelet and clasp as a weak point, with criticisms including pin-and-collar construction, stamped clasps, and a lack of a convenient diver's extension. Some reviewers also note potential issues with bezel alignment and day/date wheel alignment. On balance, owners and reviewers rate the Seiko Prospex Sea Save the Ocean Special Edition highly for its exceptional dial design and overall value.
