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

Owners widely praise the Seiko Prospex SPEEDTIMER for its unique dial colors and vintage-inspired design, with many appreciating its compact 39mm case size and 100m or 200m water resistance. Reviewers and owners note the V192 solar movement’s power reserve indicator and its reliability, though some owners express a preference for automatic movements. One owner finds the $700 price for a solar quartz model expensive, while another criticizes the €860 price point and desires a thinner case and a bracelet with quick-release or micro-adjustment. On balance, owners and reviewers appreciate the Seiko Prospex SPEEDTIMER for its distinctive aesthetic and versatile wearability, despite some reservations about its price and case thickness.

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.
