What people say

Owners + reviewers, side by side

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

Sinn EZM 12

The Sinn EZM 12 is widely praised as a purpose-built tool watch for air rescue and medical professionals, with reviewers highlighting its innovative design for critical timing, including a one-hour countdown bezel, an internal 10-minute bezel, and a pulsometer for pulse-taking. Its Tegiment hardened case, Ar dehumidifying capsule, and easily removable components for decontamination and strap changes are consistently noted as practical strengths. Owners and reviewers also point to its value at around €2,527/$3,340 and robust magnetic resistance. However, some owners find the dial layout busy and the lume on the hands disappointing, while the winding and inner bezel crowns are reported as difficult to operate, and the 38-hour power reserve is considered less robust than expected for its serious purpose. Overall, owners and reviewers rate the Sinn EZM 12 highly for its unique, practical design and robust construction tailored for demanding professional use.

From video reviewers

The tegimented case and bezel offer superior scratch resistance. The dual rotating bezels, an inner count-up and outer countdown, allow for monitoring multiple timeframes simultaneously. Reviewers noted the pulse rotor for measuring heart rate as a unique function.

Glycine Combat Sub

Owners widely praise the Glycine Combat Sub for its exceptional thinness, with many noting its 10.4mm to 10.8mm profile for a diver, perfect proportions, and solid build quality that offers significant value, especially at discounted prices. Its unique aesthetic is appreciated for avoiding homage looks, and the lug design contributes to a smaller perceived wear size despite its 42mm case. Some owners report an inconsistent power reserve and sub-par lume that can be difficult to read at night, while one owner noted a slightly off-color lume pip on the chapter ring. Overall, owners rate the Glycine Combat Sub highly for its refined feel, slim profile, and value proposition.

From video reviewers

The Glycine Combat Sub offers good value at its price point, with reviewers highlighting its attractive design and comfortable wear. However, multiple reviewers noted areas where cost-saving measures are apparent in the build quality.
