Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Hamilton Khaki Field King Day-Date owners widely praise its classic styling, 80-hour power reserve, and excellent value. Opinions on water resistance are split; some express concern over the 50m rating, while others find it sufficient for daily wear and swimming. One owner notes the stock strap can be stiff. Service costs range from $55 for routine maintenance to $220 for full service with movement replacement. On balance, owners rate the Hamilton Khaki Field King Day-Date highly for its classic aesthetics and impressive power reserve at its price point.
The 80-hour power reserve from the H-40 automatic movement is a significant strength. The 50-meter water resistance is considered a limitation for a field watch.
The Tissot PRX UFO Robot Grendizer 50th Anniversary is praised for its tasteful integration of anime elements onto the PRX design, featuring an engraved Grendizer bust on a sunburst blue dial with Super-Luminova, and is the first 40mm PRX to omit the date. Owners widely report huge demand, with all 1975 units selling out quickly. The packaging and watch box are described as "dope" and "insane," with one commenter stating the packing alone is "worth the buy." The watch retains the familiar 40mm case, Powermatic 80 movement with 80-hour power reserve, and integrated bracelet. Some find the Grendizer dial less appealing than the standard waffle dial, with one owner calling it "childish," while another considers it "the best PRX." The Grendizer graphic is less prominent in person than in photos, and the watch has a ghost date position. The Tissot PRX UFO Robot Grendizer 50th Anniversary retails for US$825 / CHF 795.
