All Blue. Yellow Strike. Dive Chronograph Authority.

The Alba AT3J43X is a men's Active quartz dive chronograph that commits fully to blue. The full blue unidirectional dive bezel flows seamlessly into a deep blue sunburst dial — a rich, saturated cobalt that shifts from dark navy at the centre to vivid blue at the edges under light. Three tone-on-tone blue sub-dials maintain the immersive blue composition, while a single yellow chronograph centre seconds hand cuts through the blue with sharp, high-visibility precision. At 45mm with 100M water resistance and a 60-minute chronograph accurate to 1 second, this is a dive chronograph built for those who go all in. Japan movement backed, Seiko quality assured.

Why You'll Love It

The AT3J43X and AT3J37X are the two faces of the same dive chronograph story — one Coke, one all blue. Where the AT3J37X references the black-and-red GMT heritage, the AT3J43X is the pure dive watch: blue bezel, blue dial, blue sub-dials, and a single yellow seconds hand that brings the whole composition to life. The yellow accent on a blue dial is one of the most satisfying colour combinations in sport watch design — clean, bold, and instantly legible. At 45mm it wears with real authority, and the sunburst dial guarantees it looks different in every light condition. The one for those who love blue, uncompromisingly.
