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 Auto Chrono

Owners widely praise the Hamilton Jazzmaster Auto Chrono for its value and dressy yet substantial look. The H-31 or adapted 7753 movement is noted, alongside a 60-hour power reserve. Some owners prefer a 3-6-9 subdial layout or a smaller case size, and the movement's thickness makes it unsuitable for those seeking a slim watch. On balance, owners rate the Hamilton Jazzmaster Auto Chrono highly for its value and refined aesthetic.

Lorca MODEL No.2 CHRONOGRAPH

The Lorca MODEL No.2 CHRONOGRAPH is praised for its well-made construction and vintage-inspired aesthetic, featuring a 37mm case, a balanced three-register dial, and a quality bracelet and clasp suitable for daily wear. It includes a manual-wind Sellita SW510M movement with a 63-hour power reserve and offers 100 meters of water resistance in a thin package. Reviewers note a unique grooved bi-directional bezel, which is described as an atypical but potentially divisive choice for a chronograph. On balance, reviewers find the Lorca MODEL No.2 CHRONOGRAPH to be a well-made watch that successfully blends vintage charm with contemporary design.

From video reviewers

The Lorca Model No.2 Chronograph features a notable guilloché bezel that adds vintage flair to its design. The watch is powered by a Swiss Sellita SW510M manual movement, offering 63 hours of power reserve. A potential drawback is the relatively small 37mm size.
