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 SSGPQ

The Marathon Jeep Willys SSGPQ is a vintage-inspired sports watch with a handsome dial honoring military heritage and a unique case shape. It features a 41mm stainless steel case with a matte parkerized finish, a sapphire crystal, and a MaraGlo luminous dial, powered by an ETA F06.402 quartz movement. Reviewers note that its longer lugs may extend past smaller wrists and the included leather strap is fragile. The Marathon Jeep Willys SSGPQ is available for $500 to $650 USD. On balance, reviewers find the Marathon Jeep Willys SSGPQ to be a good value, particularly for vintage Jeep enthusiasts, due to its design and heritage-inspired dial.

From video reviewers

The 41mm case size is a shared strength. Reviewers noted the bracelet clasp lacks micro-adjustments.
