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.

Tissot Le Locle Open Heart

Owners widely praise the Tissot Le Locle Open Heart for its elegant aesthetic, featuring a guilloché dial and Roman numerals, and appreciate its practical 80-hour power reserve and Nivachron hairspring. The watch is also noted for offering dual bracelet and strap options, along with a see-through case back. However, one owner flags negative community feedback regarding the comfort of the synthetic leather strap. Overall, owners rate the Tissot Le Locle Open Heart highly for its attractive design and impressive technical specifications at its price point.
