Oris Divers Sixty‑Five DatevsSeestern S450 Ocean Star

Owners praise the Oris Divers Sixty‑Five Date for its fun color variations, comfortable strap, and slim, wearable case size. One owner notes the bezel has zero grip despite minimal backplay and perfect alignment. However, one owner experienced significant issues including the watch stopping under warranty, bracelet pin failures leading to a lost link, and internal moisture and corrosion appearing two years after a service.

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.
