What people say

Owners + reviewers, side by side

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

Gruppo Gamma Vanguard Steel

The Gruppo Gamma Vanguard Steel is praised for its aged steel case and cream sandwich dial. However, some owners dislike the distorted sapphire crystal and the absence of minute markers, with one noting difficulty in replacing the crystal due to hand fitment. The watch features a Miyota 9039 movement with a 42-hour power reserve and an accuracy range of -10 to +30 seconds per day, and is offered with two strap options. On balance, owners value the Gruppo Gamma Vanguard Steel for its distinctive aged aesthetic and dial design, despite some reservations about the crystal.

From video reviewers

Movement accuracy is a notable strength, with one reviewer noting a -1.8 second per day deviation after initial testing. A weakness is the substantial price hike for the re-release model, which raises questions about whether the upgrades justify the cost. Reviewers disagree on the watch's originality, with one calling it "decidedly derivative" and the other not mentioning this aspect.

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.
