The blue-dial Hamilton Khaki Navy Scuba Auto 43mm, reference H82505140, is listed with a ceramic bezel, 300 m water resistance and an 80-hour power reserve. Those specifications apply to this exact reference; they should not be confused with the separate colorful Khaki Navy Scuba models Hamilton announced in 2024, which have a 100 m rating and aluminum bezels.
What is the Hamilton Khaki Navy Scuba Auto H82505140?
H82505140 is Hamilton’s blue-dial Khaki Navy Scuba Auto with a 43 mm stainless-steel case and bracelet. Hamilton’s current product listing identifies it as part of the collection and specifies an automatic H-10 movement, ceramic bezel and 30-bar (300 m) water resistance. These are manufacturer-listed details, not independent test results.
The title’s “updates and improves” framing should be treated cautiously: the available official information does not establish when H82505140 debuted or that it is the 43 mm successor to the colorful 2024 models.

How it differs from Hamilton’s 2024 Scuba updates
Hamilton’s May 2, 2024 release, “Fun in the Sun: The Khaki Navy Scuba Gets Three Bold, Bright Updates,” describes three colorful models with aluminum bezels, rubber straps and 100 m water resistance. It does not identify them as reference H82505140 or state their case size. The distinction matters: the release’s specifications cannot be used to describe this 43 mm blue-dial watch.
| Detail | H82505140 | Colorful models in the May 2, 2024 release |
|---|---|---|
| Water resistance | 300 m, per the exact-reference product page | 100 m, per the release |
| Bezel | Ceramic, per the exact-reference product page | Aluminum, per the release |
| Strap or bracelet | Stainless-steel bracelet listed | Rubber strap, per the release |
| Case size | 43 mm | Not stated in the release |
Hamilton described the release models as “Capable on the water and at depths up to 100 meters, the Khaki Navy Scuba is an equally suited and stylish companion on land.” That promotional statement refers to the 2024 models and their stated 100 m rating, not H82505140. See the Hamilton press release.

The 300 m rating, ceramic bezel and 80-hour reserve are Hamilton’s published specifications. They establish what the manufacturer claims for this reference, but do not by themselves demonstrate real-world timing performance, pressure-test results, or suitability for a particular dive. No independent test or firsthand wear assessment is established here.
