What people say

Owners + reviewers, side by side

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

Sternglas Naos XL Automatik

Owners widely praise the Sternglas Naos XL Automatik as an amazing and best affordable automatic Bauhaus watch for its price. However, some owners find the 42mm case size too large, with one describing it as resembling a "flying saucer" on a 7.25-inch wrist, and another noting its unsuitability for a predominantly white dial. The Miyota movement is described as just okay. Overall, owners rate the Sternglas Naos XL Automatik highly for its value proposition as an affordable Bauhaus automatic.

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.
