Hamilton has refreshed the Khaki Navy Scuba Auto 40mm with new wave-pattern dials and additional colourways.
It’s a measured update rather than a reinvention, but it gives one of the brand’s most approachable nautical-minded automatic watches a more expressive face.
For buyers who like the proportions of a 40mm sports watch but want something with more texture than a flat dial, this is where the update earns its attention.

At a glance
- Hamilton has introduced new wave dials and colourways for the Khaki Navy Scuba Auto 40mm.
- The main design change is a textured dial treatment that brings a stronger maritime character to the watch.
- The update broadens the 40mm Khaki Navy Scuba Auto line for buyers looking for a compact automatic sports watch with more visual personality.
Wave-textured dials give the Scuba Auto more depth
The key change is the dial, where Hamilton has added a wave motif that immediately pushes the watch further into its nautical identity.
Wave dials can easily become decorative for decoration’s sake, but on a watch named Khaki Navy Scuba, the treatment feels thematically coherent.
It also changes how the watch reads on the wrist.

A textured surface catches light differently from a plain dial, adding movement without relying on oversized details or unnecessary complexity.
A compact case size with broader appeal
The 40mm case remains central to the appeal of this Khaki Navy Scuba Auto.
In a category where sports watches often lean larger, 40mm is a useful middle ground for daily wear.

That size should appeal to buyers who want a watch with enough presence to feel purposeful, but not so much bulk that it becomes limited to casual or weekend use.
The new colourways add choice without changing the basic proposition of the model.
A familiar Hamilton formula with fresher styling
The Khaki Navy Scuba Auto has long sat in Hamilton’s range as a practical, accessible automatic sports watch with marine styling.

This update doesn’t appear to chase a radical new identity, which is probably wise.
Instead, the wave dials give the collection a more contemporary surface treatment while keeping the name, size and automatic format intact.
That makes the new versions especially relevant for someone considering a first mechanical sports watch, or for an existing Hamilton owner looking for a more colourful everyday option.
