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.

Marathon Jeep Willys SSGPM

The Marathon Jeep Willys SSGPM is praised for its handsome, retro design and attractive, clean dials with great hands. Owners note the case is nicely shaped and offers good value at $650 USD. However, some find the lugs extend far on smaller wrists, and the corporate Jeep logo detracts from the dial's appeal for some. The leather strap may need replacement with regular wear. Overall, owners and reviewers rate the Marathon Jeep Willys SSGPM highly for its retro design and value, despite some reservations about the Jeep branding and strap.
