Sea Ram

The diver with squared-off, aggressive lines, also available as a chronograph

Model History

The Sea Ram stands out in the Deep Blue catalogue for a more muscular aesthetic language than the brand's more classic divers: squared case flanks, thick and voluminous crown guards and a 120-click bezel with blunt, squared teeth, described by industry observers as particularly "aggressive" in design. The name itself, evoking a sea ram, reflects this decidedly muscular stance.

Presented as a standalone collection in the mid-2010s, the Sea Ram offered from the start a fairly wide range of movements for a single line: three-hand versions powered by a Swiss Ronda quartz movement, quartz chronograph variants with multiple counters, and finally an automatic version with a Japanese Miyota 9015 movement, covering different price and complication tiers while keeping the same case layout.

The dial has been offered in numerous color variants, from a more subdued black to brighter sun-ray tones to mother-of-pearl executions, paired with bezels featuring a matching colored ceramic insert. The line also includes the Sea Ramic, a reduced 36 mm version designed for a woman's wrist, a sign of the brand's intent to broaden the collection's audience beyond the sport-sized diver.

Fun Fact

Within the same Sea Ram collection sit three entirely different movement families — simple quartz, quartz chronograph and automatic — a fairly unusual approach for a microbrand, which lets Deep Blue offer the same case aesthetic across widely different price and complication tiers.
