What people say

Owners + reviewers, side by side

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

Seiko Prospex SPEEDTIMER Seiko 145th Anniversary Limited Edition

Owners widely praise the Prospex SPEEDTIMER Seiko 145th Anniversary Limited Edition for its refined presence and intricate dial patterns, with some favoring its unique red dial and steel bezel over other Speedtimer models. However, some owners criticize the 24-hour subdial as useless, the date window as recessed, and the stock bracelet as difficult to fit, while others find the pushers stick out too much. One owner notes the $995 price point is high for the 6R55 movement, suggesting a lower range, though others appreciate the Seiko finishing and charm. On balance, owners rate the Prospex SPEEDTIMER Seiko 145th Anniversary Limited Edition well for its unique aesthetic and finishing, despite some functional and value concerns.

Yema Diver

One owner reported a water ingress issue on their Yema Diver the first time it got wet in a lake, despite rinsing and inspecting the watch and bezel. Another owner notes this manual wind Yema Diver has a cool patina but is unlikely to be waterproof or gain value. Overall, owners view the Yema Diver as a fun second watch rather than an investment.

From video reviewers

The Swiss Sellita movement is a notable feature. Reviewers did not reach a consensus on any weaknesses.
