Official specifications make the family easy to compare, but they do not establish a firsthand review of weight, comfort, accuracy, or durability. This guide separates Hamilton’s specifications from editorial observations and identifies each model by reference.
Which Hamilton Khaki Field Titanium references are covered?
The official pages cited here cover three references: the 38 mm H70215130 and the 42 mm H70665130 and H70665533. Their shared Titanium Auto name does not make their configuration or availability interchangeable. Check the reference on a product page or retailer listing before relying on a detail.
| Reference | Size and configuration | Hamilton-listed specifications | Collection status on cited page |
|---|---|---|---|
| H70215130 | 38 mm; black PVD-coated titanium case | Automatic H-10; 11.68 mm thick; 46 mm lug-to-lug; 20 mm lug width; 80-hour power reserve; sapphire crystal; 10 bar (100 m) water resistance; open case back; Nivachron balance spring; Super-LumiNova | Hamilton marks it past collection; its US listing says it is not available online. |
| H70665130 | 42 mm; black PVD-coated titanium case and bracelet | Automatic H-10; 11.45 mm thick; 20 mm lug width; 80-hour power reserve; sapphire crystal; 10 bar (100 m) water resistance; open case back; Nivachron balance spring; Super-LumiNova | Hamilton marks it past collection on the cited international page. |
| H70665533 | 42 mm; titanium case with black PVD coating | Automatic H-10; 20 mm lug width; 80-hour power reserve; 10 bar (100 m) water resistance | Hamilton’s US page lists it as current collection. The page showed $1,245 and in-stock status when crawled in 2026; price and stock can change. |
Specifications in the table are Hamilton’s published figures, accessed in 2026. Hamilton’s H-10 movement description calls it a three-hand movement available with or without a date function; that general description does not mean every H-10 watch has a date display.
How do the 38 mm and 42 mm versions compare?
H70215130: 38 mm
The 38 mm H70215130 is the smaller-diameter option in this comparison. Hamilton lists a 46 mm lug-to-lug measurement and 20 mm lug width for this reference, along with a black PVD-coated titanium case. The lug-to-lug figure is useful when considering how the watch may span the wrist, but it cannot determine fit on its own.

H70665130 and H70665533: 42 mm
The 42 mm H70665130 is explicitly listed with a black PVD-coated titanium case and bracelet. The H70665533 is also 42 mm and has a black PVD-coated titanium case, but do not assume its bracelet or every other detail matches the H70665130: consult the exact product listing. Hamilton lists a 20 mm lug width for both 42 mm references, but the cited pages do not give their lug-to-lug measurements.
Diameter is only one part of fit. Wrist shape, lug span, thickness, bracelet or strap, and personal preference all matter; the published dimensions are not a substitute for trying on the exact reference.

What do the movement and water-resistance specifications mean?
For H70215130 and H70665130, Hamilton lists an automatic H-10 movement, an 80-hour power reserve, sapphire crystal, and 10 bar (100 m) water resistance. Hamilton lists an H-10, 80-hour reserve, and 10 bar water resistance for H70665533 as well. Confirm the specification on the page for any other reference rather than transferring it across the family.
- 80-hour power reserve: Hamilton’s stated reserve for these references. It describes the movement’s specified running time when fully wound, not a guarantee of real-world accuracy.
- 10 bar (100 m) water resistance: a manufacturer rating, not by itself proof of suitability for diving or any particular water activity. Follow Hamilton’s guidance for the specific watch and its condition.
- Sapphire crystal: listed for H70215130 and H70665130. A material specification does not mean the crystal is scratch-proof.
- Automatic H-10: a mechanical movement specification. Hamilton says its H-10 comes in versions with or without a date function, so check the dial and reference rather than inferring the display from the caliber name.
What is established about titanium and the wearing experience?
Hamilton positions titanium as lightweight and strong, but the cited product information provides no comparative mass measurement or independent strength test for these watches. There is likewise no basis here to state how light, comfortable, accurate, luminous, or durable a specific example feels in use.

Fratello published a separate hands-on article on the Hamilton Khaki Field Titanium Auto. Any wearing impressions belong to that publication and should be read as its editorial observations, not as a test of every reference or a first-person report about the watches listed above.
Hamilton and Swatch Group have also presented color and design context for the product family. A 2020 Swatch Group announcement says new colors recalled patina found on vintage Hamilton field watches; that is historical product context, not proof that every current Titanium reference directly reproduces a particular vintage model. See the Hamilton press page and Swatch Group’s 2020 announcement.

Can you change the strap?
Hamilton lists a 20 mm lug width for all three references in this comparison, which gives you a starting measurement when considering another strap. Lug width alone does not confirm that a particular strap, end link, or attachment will fit correctly. Check compatibility for the exact reference before buying or fitting one.
Are these models still available?
Availability depends on the reference, region, and date. Hamilton marks H70215130 as past collection and its cited US page says it is not available online; the cited international H70665130 page also marks that reference past collection. By contrast, Hamilton’s cited US listing shows H70665533 as current collection. The same listing showed $1,245 and in-stock status when crawled in 2026; those figures are a dated snapshot, not a promise of today’s price or stock. Check the relevant regional Hamilton page or an authorized retailer for current availability.
