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.

Seestern S450 Ocean Star

Owners widely praise the Seestern S450 Ocean Star's Yachtmaster-style case and flawless bracelet finishing, with one owner noting the ST2130 movement keeps good time. The bezel action is described as having individual notches but feeling like a friction bezel, while another owner flags the bezel and crown action as smooth with perfect alignment. Lume is a point of contention, with one source describing it as a nice cool blue with ice-white application, while others note it as weak or not matching Prospex standards, despite using BGW-9. The watch is considered a "big boy" ideal for larger wrists (19cm+), potentially too large for 17cm wrists due to its size and non-tapering bracelet. Overall, owners rate the Seestern S450 Ocean Star highly for its build quality and finishing at the price point, despite some reservations about its size and lume intensity.
