Hamilton Khaki Field Mechanical Power Reserve

The Hamilton Khaki Field Mechanical Power Reserve is noted for its 40mm sandblasted case, filling a size gap in the Khaki Field line. It features a new H-23 hand-wound movement with an 80-hour power reserve and a functional power reserve indicator at 9 o'clock. The case is 11.95mm thick, which is described as noticeably thicker than other Khaki Field models, and its proportions differ from classic manual-wind versions. The movement includes a slipping spring to resynchronize the power reserve indicator after shocks. Overall, reviewers appreciate the addition of the power reserve complication to the hand-wound model, though one reviewer noted a preference for a contrasting color on the indicator.

From video reviewers

The power reserve indicator at 9 o'clock is a functional addition to the classic design. The 40mm case size and 100m water resistance are noted strengths. Reviewers did not reach a consensus on weaknesses.

Zelos Aurora Field

The Zelos Aurora Field is praised for its unique and gorgeous dial, with the hammered teal bronze version and its great lume, particularly on the minute track, being singled out. Owners find the rubber strap comfortable and flexible with good hardware, and the watch is highlighted as feature-packed for its price point, including 200m water resistance, Grade 2 titanium, and 30,000 A/m anti-magnetism, with the new clasp noted as the best to date. However, some owners criticize sharp bracelet edges, an odd case shape with lugs that cause it to wear high, and dial text that appears cheap and plasticky, with one commenter finding the straight lugs look a bit off. Overall, owners rate the Zelos Aurora Field highly for its value and unique dial, despite some concerns about case and bracelet finishing.
