Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Gruppo Gamma Vanguard Steel

Owners widely praise the Gruppo Gamma Vanguard Steel's aged steel case and cream sandwich dial. Some owners, however, note distortion from the sapphire crystal and a lack of minute markers. One owner found the crystal distortion problematic and mentioned difficulty with replacement due to hand fitment. The Gruppo Gamma Vanguard Steel is priced at $730 and features a forged carbon dial with 'Old Radium' Super-LumiNova. Overall, owners appreciate the Gruppo Gamma Vanguard Steel for its distinctive dial and aged case finish, 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.

Praesidus Service

Owners widely report issues with Praesidus customer service, citing slow response times and unresolved problems. One owner noted the domed glass offers vintage distortion and the unbranded dial appeals to history buffs, but experienced jumpy hand sensitivity when setting the time. Another owner reported a scratchy crown and rotor issues that persisted after warranty service, followed by a locked crown. On balance, owners express significant dissatisfaction with customer service and product reliability, overshadowing any positive design elements.

From video reviewers

The 38mm case size is a strength for those preferring smaller watches. The dial may show slight discoloration or unevenness in finish.
