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.

Oak & Oscar The Olmsted 38

Oak & Oscar The Olmsted 38 is praised for its sharp, stealthy aesthetic with a durable ceramic-coated stainless steel case and a clean, no-date dial. Reviewers highlight its excellent wearability at 38mm and the value proposition at $1,475, which includes two strap options. The watch features a sandwich dial with stencil numerals and orange accents, powered by a modified ETA 2892-A2 movement. Overall, reviewers find Oak & Oscar The Olmsted 38 to be a modern and aggressive take on the classic field watch, offering exceptional value.

From video reviewers

The Olmsted 38 features tightly executed tolerances and an ultra-fine level of finishing. Reviewers did not reach a consensus on any weaknesses. Reviewers did not explicitly disagree on any points.
