The red-bezel Hamilton Khaki Navy Scuba Auto is reference H82405130: a 40mm stainless-steel automatic watch with a black dial, red aluminum bezel and 100m water-resistance rating. Its bold bezel sets it apart from the conventional steel case and bracelet, but the rating is more suited to everyday water use than to buyers seeking a purpose-built dive watch. Hamilton’s UK page currently lists it as past collection and unavailable online; that does not establish its status in every market.
What is the red-bezel Khaki Navy Scuba?
H82405130 is the specific reference for the black-dial, red-bezel version of Hamilton’s Khaki Navy Scuba Auto. Other watches in the Scuba family have different colors and specifications, so check the reference when comparing listings. Hamilton describes this model’s bezel as sandblasted red aluminum, a treatment it says gives the color a softer, deeper tone and muted shine. The brand also connects the red to ocean rescue teams and the port side of sailing boats; that is Hamilton’s design explanation.
In its October 2024 first look, Monochrome Watches described the case as mostly brushed steel with polished accents. It noted applied dial markers, a date window at 4:30, a red-tipped seconds hand, and an inner 13–24 hour scale that recalls Hamilton’s military history. The bezel has a unidirectional action and 60-minute scale, according to that coverage.

What does the 100m water-resistance rating mean?
Hamilton specifies 10 bar, or 100m, of water resistance and lists a screw-down crown. Those are the manufacturer’s stated specifications, not proof that this particular watch has been independently certified as a dive watch. The consulted sources do not establish an ISO 6425 certification for H82405130.
Monochrome characterized the Scuba as a sporty watch with aquatic styling rather than a proper dive watch, noting that 100m may feel limited to some buyers. That is the publication’s assessment, not Hamilton’s classification. Hamilton’s May 2, 2024 press release described the Scuba collection as “capable on the water and at depths up to 100 meters”; that is promotional language about the collection.
