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.

Nodus Duality II

Owners widely praise the Nodus Duality II for its refined dial construction, improved proportions, and wearability with a thinner 11.5mm case. The dual-crown functionality for movement and internal rotating bezel is a key feature, alongside 300 meters of water resistance and a durable three-link bracelet with the NodeX extension. The Miyota Cal. 9015 movement is noted, with some owners preferring Nodus finishing over alternatives. One owner finds the Nodus Duality II overpriced at $868, citing a loud rotor and lower-quality bracelet, while others argue US assembly, the movement, and the internal bezel justify the cost. On balance, owners and reviewers rate the Nodus Duality II highly for its refined design and wearability at its price point.
