Reviews

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

Glycine Airman GMT

Owners widely praise the Glycine Airman GMT's classic pilot design and consider it a well-made watch. Some owners find the GMT hand visually similar to the minute hand, which can be frustrating. The Sellita-based movement kept acceptable accuracy. On balance, owners and reviewers appreciate the Glycine Airman GMT for its classic pilot design and build quality.

Zelos Spearfish GMT

Owners widely praise the Zelos Spearfish GMT for its exceptional value and build quality, with one owner noting it garners more compliments than higher-end watches. Reviewers highlight its excellent machining, flawless finishing, and a superb bracelet featuring tool-less micro-adjustment that surpasses its price point. The watch is powered by a Sellita SW330-2 automatic movement. Some owners report accuracy around +2.6 seconds per day, while others note a minor compromise in end link fit. Overall, owners and reviewers rate the Zelos Spearfish GMT highly for its impressive finishing and bracelet at its $645 price.

From video reviewers

The bezel action is a strong point. The bracelet quality is a weakness. Reviewers disagreed on the dial material, with some mentioning aventurine and others meteorite.
