Owners + reviewers, side by side

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

Islander Northport 37mm Automatic Watch with Purple Ripple Dial #ISL-291

The Islander Northport 37mm Automatic Watch with Purple Ripple Dial #ISL-291 is widely praised for its looks, build quality, and impressive specifications, including a high-beat Miyota 9015 movement with hacking and hand-winding, sapphire crystal, and 200m water resistance. Owners consider it excellent value, citing the finishing and comfortable fit. One owner notes the bright lume is fleeting. The watch is powered by a Miyota 9015 movement with a 40-hour power reserve. Overall, owners and reviewers rate the Islander Northport 37mm Automatic Watch with Purple Ripple Dial #ISL-291 highly for its exceptional value and robust specifications at its price point.

Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation

The Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation is noted for its refined, slimmed-down 39.5mm stainless steel case with a "super hard" coating and a box-shaped sapphire crystal. It offers 200 meters of water resistance and is powered by the slim Caliber 6L37 automatic movement, which has a 46-hour power reserve and an accuracy rating of -10/+15 seconds per day. Reviewers highlight its wearability and functionality as a dive watch, with one noting it as Seiko's thinnest diver ever at 12.3mm. However, concerns are raised about Seiko's continued reliance on the 62MAS design, with one reviewer wishing the Marinemaster remained a separate line, and the bracelet's end-links appearing mismatched in initial images. Its price of A$4,650 is considered high given its specifications compared to competitors.
