What people say

Owners + reviewers, side by side

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

Breitling Superocean Heritage B31 Automatic

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.

Seiko 5 Sports SKX series

The Seiko 5 Sports SKX series is widely praised for its value, robust build, and powerful lume, with owners appreciating its comfortable bracelets and improved movement featuring hacking and hand-winding. Some owners find the original SKX models heavy and bulky, while others praise their ruggedness and iconic dive watch design. Reviewers note the 38mm models offer great value at around €350 and are exemplary gateway watches, though their 100m water resistance without a screw-down crown makes them unsuitable for diving. The Seiko 5 Sports SKX series is seen as a decent watch, especially under £200, but lacks the tool watch capabilities of the original SKX, missing a screw-down crown, bezel pip, and ISO rating. On balance, owners and reviewers rate the Seiko 5 Sports SKX series well for its blend of value, improved movement, and tool-watch aesthetic, despite some missing dive certifications.
