Hamilton Khaki Field Titanium H70555533
42mm titanium field watch with 80-hour H-10 movement · Reviewed by Drew · amazon.com live, Sept 24 2026
Why it scored a 79
The Hamilton Khaki Field Titanium H70555533 has one of the strongest spec sheets here: a 42mm titanium case, sapphire crystal, 100m water resistance, Super-LumiNova and the Swiss H-10 movement with an 80-hour reserve. Quality scores 88 and Features 86. The rest of the rubric is less kind. At $795.00 Value is 70, tied for the lowest, the 2-year warranty scores 66, and 4.2 stars from 103 ratings gives Satisfaction 82, the lowest in the group. It ties the Seiko 5 Sports SRPD93 at 79 and ranks #8 on the Value tiebreak.

Should you buy the Hamilton Khaki Field Titanium H70555533?
The Hamilton Khaki Field Titanium H70555533 is for a buyer who wants a light Swiss field watch that keeps running through a weekend off the wrist. At $795.00 it ranks #8 of 10 in our Automatic Watches category. The specs are excellent; the ratings and price are what hold it back. If you want Swiss and 80 hours with better owner scores, the Tissot PRX Powermatic 80 Blue 40mm is $850.00. If price matters most, the Citizen Tsuyosa NJ0150-56X is $371.25.
Where it earns its score
- Titanium case. It is the only titanium watch in our category, lighter on the wrist than the steel cases around it.
- 80-hour H-10. The Swiss H-10 runs about 80 hours, roughly double the 41 hours of Seiko's 4R36.
- Sapphire and lume. A sapphire crystal and Super-LumiNova on a black dial keep it legible and scratch-resistant.
- 100m rating. Ten bar is enough for swimming, twice the rating of the Seiko Presage Cocktail Time SRPB41.
What to know first
- Warranty is the lowest factor at 66. Hamilton's 2-year international warranty trails Seiko's 3 years and Citizen's 5.
- Weakest owner scores here. 4.2 stars across 103 ratings gives Satisfaction 82, the lowest in our category.
- Listing inconsistency. The title says titanium while one bullet says stainless steel; H70555533 is Hamilton's titanium reference, so confirm before buying.
Our verdict
The Hamilton Khaki Field Titanium H70555533 scores 79, a Fair Buy and #8 in our Automatic Watches category. Quality (88) and Features (86) are near the top, but Value (70), Warranty (66) and Satisfaction (82) pull it down. Buy it at $795.00 if you want titanium and an 80-hour Swiss movement. Otherwise, the Tissot PRX Powermatic 80 Blue 40mm (82) scores higher.
