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.

Gruppo Gamma Field III GMT

Owners praise the Gruppo Gamma Field III GMT for its look and value, with specific mentions of its sandwich dial and comfortable OEM straps. One owner notes incredible quality for the price across their Gruppo Gamma watches. The watch features a 40mm brushed stainless steel case, box sapphire crystal, and a Seiko NH34A movement with a 41-hour power reserve and stated accuracy of -20~+40 s/day. Some find the lack of a date window a drawback for a GMT, and question its differentiation from other NH34-powered watches. On balance, owners and reviewers find the Gruppo Gamma Field III GMT to be a good value with quality construction for its price point.
