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.

Lorier Hyperion SII Skyward

Owners widely praise the Lorier Hyperion SII Skyward for its comfortable, thin, and light wearability, with one owner noting a perfect case width and another highlighting its 10.7mm thickness. The bi-directional GMT bezel is described as decent for its price, and the movement is considered fine and accurate, making it a low-key travel watch. The bracelet is also noted as well-made and finished for the price. On balance, owners rate the Lorier Hyperion SII Skyward highly for its comfortable wearability and value as a mechanical GMT.
