Hamilton currently lists two Khaki Field Quartz models in the US: the 33mm H69301930 and the 38mm H69401930. Both have quartz movements, sapphire crystals, stainless-steel cases and a published water-resistance rating of 5 bar (50m). The practical differences are size, thickness, caliber listing and strap width: the 33mm takes an 18mm strap, while the 38mm takes a 20mm strap.
What is the difference between the 33mm and 38mm Hamilton Khaki Field Quartz?
The 38mm model is 5mm wider and 5mm longer from lug to lug than the 33mm. It is also 0.75mm thicker and uses a wider strap. Both have black dials, stainless-steel cases, sapphire crystals, Super-LumiNova and a textile strap, but their published calibers and strap references differ.
| Specification | 33mm H69301930 | 38mm H69401930 |
|---|---|---|
| Movement and caliber | Quartz; ETA F05.105 mh2 | Quartz; F06.105 |
| Case diameter | 33mm | 38mm |
| Thickness | 7.55mm | 8.3mm |
| Lug to lug | 41mm | 46mm |
| Lug width | 18mm | 20mm |
| Dial, case and crystal | Black dial; stainless-steel case; sapphire crystal | Black dial; stainless-steel case; sapphire crystal |
| Water resistance | 5 bar (50m) | 5 bar (50m) |
| Lume | Super-LumiNova | Super-LumiNova |
| Supplied strap reference and type | H6000002241; textile | H6006941021; textile |
These specifications are listed on Hamilton’s 33mm H69301930 page and 38mm H69401930 page.
Which size should you choose?
Choose by proportions, not diameter alone
Case diameter gives a quick sense of scale, but lug-to-lug length helps show how much of the watch spans the wrist. The 33mm model measures 41mm lug to lug; the 38mm measures 46mm. Those figures, along with the difference in thickness, offer a more useful comparison than diameter alone. Hamilton’s published specifications do not provide wrist-size recommendations, and the dimensions do not establish how either watch will fit a particular person.

Consider the strap width
The 33mm model’s 18mm lug width and the 38mm model’s 20mm lug width mean their straps are not interchangeable at the lugs. For an aftermarket strap, match the width to the reference and check with the seller that its construction, spring-bar fit and buckle are compatible. Hamilton lists textile straps for both models; its product pages do not endorse aftermarket alternatives.
What does Hamilton say about the design?
Hamilton presents the collection as a return to its military heritage, emphasizing simple design, clear Arabic numerals and a railway minute track. The product copy describes a black dial, old-radium-colored Super-LumiNova indices and a green textile NATO strap with brown leather loops. These are Hamilton’s descriptions and positioning, not an independent assessment of the watches’ historical lineage.

Hamilton calls the 38mm watch “a reliable and rugged companion ready for exploration.” The phrase is brand positioning, not evidence of independent field testing. Hamilton also states that quartz mechanisms are known for accuracy, with “only a one-minute variation annually”; that is a general statement about quartz mechanisms, not a measured accuracy result for either reference.
Is the Hamilton Khaki Field Quartz water resistant?
Hamilton publishes a 5 bar (50m) water-resistance rating for both models. That specification alone does not establish which activities are suitable for these exact references; the product pages do not list approved water-use conditions. For reference-specific guidance, check with Hamilton rather than treating the depth figure as a promise of suitability for swimming, diving or another particular activity.

What care and battery guidance is available?
Hamilton’s general Khaki X-Wind instruction manual, marked 10.2025, says water resistance can be compromised as gaskets age or after impacts. It recommends annual water-resistance checks at an authorized Hamilton Service Center, authorized battery replacement and prompt replacement of an empty battery to reduce leakage risk. Because this manual is for the X-Wind, treat that as general Hamilton guidance and ask Hamilton for instructions specific to the Khaki Field Quartz.
The same X-Wind manual says watch-battery lifespan typically ranges from two to five years depending on the movement and its energy demands. That broad figure is not a battery-life specification for either Khaki Field Quartz reference; Hamilton’s reviewed product pages do not state a model-specific battery type or replacement interval.
