What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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 1970 Heritage Diver's Save the Ocean Special Edition

The Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition is praised for its beautiful design and refinement over previous models, featuring vertically textured glacier-inspired dials. Owners, however, consider the €1500 RRP too high, suggesting a price closer to €900-€1000, noting the aluminum bezel insert instead of ceramic. Some owners report the 6R movement runs slow. On balance, owners find the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition beautiful and a refinement, but the price and aluminum bezel are points of contention.
