What people say

Owners + reviewers, side by side

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

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.

Yema Superman Bronze CMM.10

The Yema Superman Bronze CMM.10 is praised for its neo-vintage dive watch aesthetic, featuring a bronze case with brushed and polished finishing and a gradient blue sandwich dial with Super-LumiNova. It is powered by the in-house CMM.10 automatic movement, which offers a 70-hour power reserve and chronometric precision rated at -3/+5 seconds per day. The watch is available in 39mm and 41mm case sizes and comes on FKM Viton rubber straps. It was offered at a pre-order price of €999. Overall, reviewers highlight the Yema Superman Bronze CMM.10 as a refined neo-vintage dive watch with a capable in-house movement and attractive finishing.
