Hamilton Khaki Field Mechanical Power ReservevsSeiko Presage Classic Series “Craftsmanship” Enamel Dial

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.

Owners and reviewers widely praise the Seiko Presage Classic Series “Craftsmanship” Enamel Dial for its high-quality, handcrafted enamel dials, with specific commendations for the depth and subtle gloss of urushi lacquer and the excellent legibility of minimalistic markers and contrasting hands. The watches are frequently cited as offering significant value, with one reviewer noting the SPB163 as a great value at €1,300, and another highlighting the series' impressive 100M water resistance and Japanese design inspiration at $1,300 USD. However, the 12.4mm to 12.8mm thickness is noted by multiple sources as a potential area for improvement, with a preference for under 12mm, and one owner dislikes the date window. Accuracy figures for the 6R27 movement range from -15 to +25 seconds per day, and its power reserve is closer to 35-40 hours than the advertised 45 hours.
