What people say

Owners + reviewers, side by side

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

Oak & Oscar The Ashland

Owners widely appreciate Oak & Oscar The Ashland for its handsome design, symmetrical dial layout, and good timekeeping, with one owner reporting -4 seconds per day. Some pre-owned examples show minor marks on the lugs, bezel, and case, along with strap wear, consistent with normal use. On balance, owners value Oak & Oscar The Ashland for its attractive design and reliable performance.

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.
