What people say

Owners + reviewers, side by side

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

Dryden Chrono Diver Gen 2

Owners widely praise the Dryden Chrono Diver Gen 2 for its exceptional value and comfortable wearability, with particular appreciation for its refined PVD finish. The watch features a Seiko VK63 Meca-Quartz movement, improved lume, and solid bezel action, all housed in a 42mm case with recessed pushers and 100m water resistance. Some owners note the 49mm lug-to-lug may be large for smaller wrists. On balance, owners rate the Dryden Chrono Diver Gen 2 highly for its amazing value and comfortable wearability.

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.
