What people say

Owners + reviewers, side by side

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

Lorier Astra

The Lorier Astra is praised for its outstanding details and design language, hitting a "dressy sports watch" vibe with a beautiful sector dial and lume. Owners note its versatile, do-it-all design with classic proportions and refined details like beveled markers, making it suitable for both formal and casual wear. The watch wears slightly larger than its 36mm case suggests, closer to 38mm, with lugs that taper and curve downward to fit well on smaller wrists. However, the bracelet feels a bit light, some screws are difficult to remove, and the Miyota movement can gain around 8 seconds in 12 hours with potentially offset date numerals. On balance, owners rate the Lorier Astra highly for its dressy sports watch aesthetic and refined details 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.
