Hamilton Khaki Field Automatic H70455733

The Hamilton Khaki Field Automatic ref. H70455733 is the 38mm stainless steel model with a satin black dial and black calfskin leather strap, part of Hamilton's Khaki Field collection. It is powered by the in-house-branded H-10 automatic caliber (based on the ETA/Powermatic 80 C07.611), offering an 80-hour power reserve, and is rated to 100 meters of water resistance.

Hamilton's field-watch lineage traces back to the trench watches it supplied around the First World War, and the company paused civilian production entirely from 1942 to 1945 to build timepieces for the US military during the Second World War, work for which it received an Army-Navy "E" Award, according to hiconsumption. Hamilton went on to produce watches to the MIL-W-46374 ground-troop specification and the GG-W-113 aviation standard from the 1960s through the 1980s, per the same review.

After Hamilton became part of the Swatch Group, these military design codes — oversized Arabic numerals, a military time scale, and utilitarian dial layouts — were reintroduced to civilian buyers under the Khaki name, as described by Teddy Baldassarre's review of the Khaki Field Automatic. The current Khaki Field Auto updates that heritage with contemporary case sizing (38mm or 41mm, versus the roughly 33mm historical originals), an exhibition caseback, and additional dial color options, while retaining the numeral-driven dial design associated with Hamilton's military watches.

At 38mm wide with an 11.5mm case height, hiconsumption's reviewer found that the watch "wears just a hair larger than its diameter suggests," describing it as feeling closer to 39mm in person, with a lug-to-lug that runs "a touch longer than you'd expect for a 38." Teddy Baldassarre's review similarly cites a 46mm lug-to-lug and 11.5mm case height as contributing to broadly wearable proportions across wrist sizes.

Shaun Seah, reviewing his own 38mm Khaki Field Automatic, called it "easily one of the most comfortable watches" he had worn, attributing this to the watch's light weight. hiconsumption's reviewer flagged the lack of effective anti-glare performance outdoors as a drawback, along with numerals that lack luminescence and a push-pull rather than screw-down crown — criticisms echoed in aggregated review commentary describing the omission of a screw-down crown on a field watch as a notable compromise.

The current Khaki Field Auto family is offered in 38mm and 41mm case sizes, in stainless steel or titanium, according to Teddy Baldassarre's review. Ref. H70455733 is the 38mm steel version with a black dial and black leather strap; Hamilton also lists a 38mm sibling, ref. H70455533, on a brown leather strap with the same black dial, H-10 movement, and 100m water resistance.

Hiconsumption's review of the 38mm Khaki Field Auto notes that a 2025 update to the line introduced sunray blue and green dial finishes alongside the existing black option, across both 38mm and 42mm sizes. Within Hamilton's Khaki Field family, the Automatic sits above the hand-wound, date-less Khaki Field Mechanical and below the more finished Khaki Field Murph, per hiconsumption's comparison.

Ref. H70455733 lists at $795 on its calfskin leather strap, as listed by TimeScape USA. Teddy Baldassarre's review places the broader Khaki Field Automatic line at "under $800 on strap," positioning it as an entry point into Swiss-made mechanical watches.

Hiconsumption's review, covering the steel bracelet configuration of the same core watch at $845, frames the Khaki Field Auto against alternatives such as the Tissot PRX Powermatic 80 for a sportier aesthetic, Hamilton's own $675 Khaki Field Mechanical for buyers who don't need a date function or automatic winding, and the $1,045 Khaki Field Murph for more refined finishing within the same family.
