What people say

Owners + reviewers, side by side

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

Marathon Jeep Willys SSGPM

The Marathon Jeep Willys SSGPM is praised for its handsome, retro design and attractive, clean dials with great hands. Owners note the case is nicely shaped and offers good value at $650 USD. However, some find the lugs extend far on smaller wrists, and the corporate Jeep logo detracts from the dial's appeal for some. The leather strap may need replacement with regular wear. Overall, owners and reviewers rate the Marathon Jeep Willys SSGPM highly for its retro design and value, despite some reservations about the Jeep branding and strap.

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.
