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.

Fortis Marinemaster M-40

Owners praise the Fortis Amber Orange for its gorgeous appearance and strong wrist presence, noting its crazy lume and 70-hour power reserve. The Doxa SUB 300T, described as having a superb, eccentric design with a highly legible dial and functional no-decompression bezel, uses an ETA 2824-2 movement. However, the SUB 300T's 42.5mm case wears large and its 14mm thickness is not ideal for dress shirts, though it boasts 1,200m water resistance. On balance, owners appreciate the Fortis Amber Orange for its striking aesthetics and impressive lume.
