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 Sea Seiko Diver’s Watch 60th Anniversary Limited Edition

The Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition features a 40mm case, 300m water resistance, and a 72-hour power reserve from the Calibre 6R55 movement, with a new grey bezel insert and a wave-patterned silvery-white dial. Owners find the watch attractive and the large case wears well without feeling bulky. However, some consider the price of €1900 for a 6R54 movement with an accuracy of +25/-15 seconds per day to be too high, and the production run of 6000 units is not seen as a true limited edition. Overall, owners find the Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition aesthetically pleasing with good wearability, but express concerns regarding its value proposition and movement accuracy for the price.
