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

The Sternglas Naos is widely praised for its refined daily wearability and Bauhaus design, with owners noting its durable construction, scratchless sapphire crystal, and flawless date mechanism. Reviewers highlight the comfortable and supple bracelet that drapes well and a date window that matches the dial. One owner advises replacing the original tan strap due to a lack of durability. The quartz movement is noted for its accuracy, and the absence of a seconds hand is seen as a unique solution to prevent misaligned markers. Overall, owners and reviewers rate the Sternglas Naos highly for its harmonious design and comfortable wear at its price point.

Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation

The Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation is noted for its refined, slimmed-down 39.5mm stainless steel case with a "super hard" coating and a box-shaped sapphire crystal. It offers 200 meters of water resistance and is powered by the slim Caliber 6L37 automatic movement, which has a 46-hour power reserve and an accuracy rating of -10/+15 seconds per day. Reviewers highlight its wearability and functionality as a dive watch, with one noting it as Seiko's thinnest diver ever at 12.3mm. However, concerns are raised about Seiko's continued reliance on the 62MAS design, with one reviewer wishing the Marinemaster remained a separate line, and the bracelet's end-links appearing mismatched in initial images. Its price of A$4,650 is considered high given its specifications compared to competitors.
