What people say

Owners + reviewers, side by side

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

Maen Manhattan 37

Owners widely praise the Maen Manhattan 37's visually rich dial and refined finishing, with some noting its sleek, trim 37mm case and impressive timekeeping. The bracelet receives mixed reactions, with some finding it cheap and lacking compared to alternatives, while others appreciate its taper and overall value. One reviewer highlights the Ultra-Thin variant's slim 7.1mm case and 100m water resistance, powered by a manually wound ETA Pesaux 7001 movement. Conversely, another owner reports a Ronda 150 movement running fast at +18s/d to +24s/d, and some with 6.5-inch wrists find the 47mm lug-to-lug distance wears larger than expected. The Maen Manhattan 37 offers excellent value with its Art Deco-inspired design and remarkable light play on the dial. Overall, owners and reviewers rate the Maen Manhattan 37 highly for its visually rich dial and refined finishing at the price.

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.
