What people say

Owners + reviewers, side by side

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

Grand Seiko SBGN027

Owners widely praise the Grand Seiko SBGN027 for its exceptional Zaratsu polishing, compact 39mm size, and versatile monochrome aesthetic, noting its thin profile and suitability as a grab-and-go watch. The 9F quartz movement delivers highly accurate timekeeping, with one owner reporting +/- 10 seconds per year. However, some find the lume limited, the bracelet lacks micro-adjustments, and the GMT hand can be easily mistaken for the minute hand. One owner reported a black index on the bezel disappearing after a couple of months. On balance, owners rate the Grand Seiko SBGN027 highly for its premium finishing and accurate HAQ GMT movement in a wearable size.

Straton Speciale Automatic or Quartz watch

Owners widely praise the Straton Speciale Automatic or Quartz watch for its great retro feel, TV-shaped case, and fun color combinations. The automatic version is reported to be accurate at approximately +2 seconds per day. The meca-quartz model starts at $320, while the automatic is around $800 with a bracelet, both featuring a 40.8mm lug-to-lug measurement for wearability. Owners consider the quartz version reasonably priced, with its value linked to its mechanical movement. Overall, owners rate the Straton Speciale Automatic or Quartz watch highly for its retro aesthetic and wearability at its price point.
