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.

Studio Underd0g Guacamole (Gen3)

Owners widely praise the Studio Underd0g Guacamole (Gen3) for its fun, cheerful, and unusual design with great colors, and one owner found its actual wrist presence perfect. Some owners, however, find the dial printing tacky and the overall design looking cheap, while others feel it is a bit pricey for what is offered. The pushers lack crispness, and the crystal is very reflective and domed too much at the edges. One owner expresses concern that it uses a Seagull ST91-B movement, known for a high failure rate. On balance, owners are split on the value proposition of the Studio Underd0g Guacamole (Gen3) at its current price point, with some appreciating its unique aesthetic and others finding the design and movement choices underwhelming.
