What people say

Owners + reviewers, side by side

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

Oris Big Crown Pointer Date Calibre 403

The Oris Big Crown Pointer Date Calibre 403 is praised for its in-house Calibre 403 movement offering a 120-hour power reserve and a 10-year warranty. Owners and reviewers highlight its good finishing, inspired dial design with luminous Arabic numerals, and the analog date complication for quick checks. The 40mm stainless steel case is 12.3mm thick with 50 meters of water resistance. Some owners find the 40mm size perfect, while others prefer the 36mm version. The deer leather strap's clasp scratches easily, and the higher price point compared to standard models is a point of discussion, with a noted owner concern about time-setting accuracy not yet addressed. Overall, owners and reviewers value the Oris Big Crown Pointer Date Calibre 403 for its impressive performance and refreshed aesthetic 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.
