What people say

Owners + reviewers, side by side

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

Echo/Neutra 1956 Chrono

Owners widely praise the Echo/Neutra 1956 Chrono for its gorgeous looks and clean design, with one owner calling it a top 5 watch in their collection. The 40mm size and included straps are noted as comfortable and wearable. Some owners find the watch difficult to read in dull lighting. One owner of a 1956 GMT reported a non-screwing crown, and another owner of a 1956 GMT noted a misaligned bezel. Overall, owners rate the Echo/Neutra 1956 Chrono highly for its aesthetic appeal and wearability.

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.
