Breitling Superocean Heritage B31 AutomaticvsSinn EZM 12

Owners widely praise the Breitling Superocean Heritage B31 Automatic for its excellent finishing and comfortable wearability, with many appreciating the sunburst dials and the redesigned mesh bracelet. The watch is noted for its versatile design, suitable for daily wear and swimming, and some owners find its weight surprisingly manageable due to the lug shape and bracelet design. The Breitling B31 movement offers a 78-hour power reserve and COSC certification. However, the watch's design is divisive, with some disliking its aesthetic and others criticizing the use of a Sellita SW200 movement at its price point, though discounts are seen to mitigate this. Some owners also find the watch too large for smaller wrists due to its lug-to-lug distance, and the white date display at 6 o'clock is a point of contention for some. Overall, owners rate the Breitling Superocean Heritage B31 Automatic highly for its finishing and comfortable wearability, despite some design and movement criticisms.

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.
