What people say

Owners + reviewers, side by side

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

Glycine Combat Sub Sport

Owners widely praise the Glycine Combat Sub Sport for its exceptional value, thin profile, and solid build quality, often noting its finishing and wearability as superior for its price point. Reviewers consistently flag its slim case, with measurements around 10.4mm to 10.8mm, and appreciate its non-homage design and comfortable lug curvature. Accuracy figures vary, with one owner reporting only 2 seconds per day loss, while another notes their Sellita SW200 movement runs at +6 to +9 seconds per day. Some owners report inconsistent power reserve not reaching the advertised 42 hours and find the lume sub-par for nighttime legibility. A few also mention sharp bracelet edges and a potentially short bracelet for larger wrists, and one owner dislikes the "COMBAT" text on the dial. On balance, owners and reviewers rate the Glycine Combat Sub Sport highly for its impressive thinness and value as a Swiss automatic diver.

Zelos Spearfish GMT

The Zelos Spearfish GMT is widely praised for its exceptional value, with reviewers highlighting its superb finishing, flawless machining, and a tool-less micro-adjustment clasp that exceeds its price point. It features a La Joux-Perret G100 movement with a 68-hour power reserve, achieving an average accuracy of +2.6 seconds per day, or a Miyota 9075 movement offering flier-style GMT functionality. The 40mm case and bidirectional 48-click ceramic bezel are well-executed, though one reviewer noted a minor compromise in the end link fit. Overall, owners and reviewers rate the Zelos Spearfish GMT highly for its impressive finishing and value proposition.
