Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Oris Big Crown Pointer Date Calibre 403 is praised for its 120-hour power reserve and anti-magnetic properties, with reviewers noting its simplified design and vibrant blue dial. Owners highlight the smooth winding feel of the in-house Calibre 403 movement, which features twin barrels. However, some owners report minor time-setting issues, and the 50-meter water resistance is considered underwhelming by one reviewer, who also notes the deer leather strap's clasp scratches easily. On balance, owners and reviewers rate the Oris Big Crown Pointer Date Calibre 403 highly for its impressive power reserve and value proposition.
The 5-day power reserve of the new in-house Calibre 403 movement is a key strength. Reviewers noted the comfortable H-link bracelet and vibrant dial color options.
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.
