Oris Big Crown Calibre 113vsSeestern S450 Ocean Star

The Oris Big Crown Calibre 113 is noted for its distinctive mint green and rose pink dial, a 43mm stainless steel case, and an in-house hand-wound movement offering a 10-day power reserve. It includes a business calendar complication, day, date, and a non-linear power reserve indicator, with excellent readability provided by Super-LumiNova. One reviewer found the bold dial color potentially clashes with a business context and wished for a smaller case size. The Oris Big Crown Calibre 113 is priced at CHF 6,350 / €6,350 and includes a five-year warranty. Overall, reviewers highlight the Oris Big Crown Calibre 113's unique dial and extensive complications as its primary draw.

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.
