What people say

Owners + reviewers, side by side

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

Hamilton Jazzmaster Open Heart Auto

The Hamilton Jazzmaster Open Heart Auto is noted for its dressy yet versatile design, featuring striking gradient dials and intricately shaped cutouts that reveal the H-10 movement. It boasts an 80-hour power reserve and Nivachron hairspring. The watch is available in 36mm, 40mm, or 42mm stainless steel cases. On balance, the Hamilton Jazzmaster Open Heart Auto is appreciated for its visually engaging dial and movement display at its price point.

From video reviewers

The smoked dial's precision cutouts offer a captivating view of the automatic movement. Legibility is compromised by the open-heart design.

Marathon Jeep Willys SSGPQ

The Marathon Jeep Willys SSGPQ is a vintage-inspired sports watch with a handsome dial honoring military heritage and a unique case shape. It features a 41mm stainless steel case with a matte parkerized finish, a sapphire crystal, and a MaraGlo luminous dial, powered by an ETA F06.402 quartz movement. Reviewers note that its longer lugs may extend past smaller wrists and the included leather strap is fragile. The Marathon Jeep Willys SSGPQ is available for $500 to $650 USD. On balance, reviewers find the Marathon Jeep Willys SSGPQ to be a good value, particularly for vintage Jeep enthusiasts, due to its design and heritage-inspired dial.

From video reviewers

The 41mm case size is a shared strength. Reviewers noted the bracelet clasp lacks micro-adjustments.
