Breitling Superocean Heritage B31 AutomaticvsSeiko Prospex Marinemaster Marinemaster 1968 Heritage Diver's Watch

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 Seiko Prospex Marinemaster 1968 Heritage Diver's Watch is widely praised for its excellent quality and finishing, with reviewers and owners noting its GS-level craftsmanship and Zaratsu-inspired polishing. Owners appreciate its refined design, comfortable case shape, and the 4:00 crown position, with some finding it more manageable on the wrist than other models. The Caliber 8L45 movement offers a 72-hour power reserve and accuracy within -5/+10 seconds per day, and the bracelet features an improved clasp with an extension system. However, some find the price point high, and one reviewer noted the unsigned winding crown as a missed opportunity. On balance, owners and reviewers rate the Seiko Prospex Marinemaster 1968 Heritage Diver's Watch highly for its premium finishing and tool-like appearance at its price point.
