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 Rallygraf Meca-Quartz II

Owners widely praise the Yema Rallygraf Meca-Quartz II for its cool retro 70s vibe, faithful reissue of a thin vintage design, and excellent build quality for its price, with particular commendation for its tactile pushers and top-notch Milanese strap. The watch is noted for its substantial, weighty feel and well-aligned indices, and the Seiko VK64 meca-quartz movement provides a sweeping chronograph hand. However, some owners find the meca-quartz ticking not very smooth, the left subdial a "useless" 24h indicator, and the watch overpriced compared to similar models. Several owners report disappointing alignment issues with indices, and one owner experienced the dial rotating slightly when chronograph pushers are depressed or when adjusting the time, with these issues not resolved during service. On balance, owners rate the Yema Rallygraf Meca-Quartz II highly for its retro styling and perceived value, despite some recurring quality control concerns.

From video reviewers

The watch's vintage-inspired design and value at its price point are consistently praised. The meca-quartz movement is mentioned as a feature by multiple reviewers.
