Full Green PVD. Crackle Dial. 20 Bar Diver Automatic.

The Alba AL4439X is a men's mechanical automatic diver watch built to go deeper than any other in the range. 20 bar water resistance — rated to 200 metres — sets it apart immediately from the 10 bar standard across the rest of the Mechanical collection. The full dark green PVD case and bezel create an immersive all-green exterior, while the green to black gradient dial with crackle texture adds a depth and dimension that looks entirely different at every angle of light. A vivid yellow seconds hand and yellow bezel lume pip introduce a sharp, high-visibility accent against the all-green composition. Worn on a dark green silicone strap for lightweight comfort during water activities. Powered by the Japan-made Y676 automatic calibre — self-winding, battery-free. Japan movement backed, Seiko quality assured.

Why You'll Love It

The AL4439X is the diver's diver in the Alba Mechanical range. The 20 bar rating is genuine — most sport watches at this price point offer 10 bar; 200 metres puts this in the same water resistance category as purpose-built dive watches. The full green PVD case is a design choice that demands commitment — and it delivers a watch that is visually unlike anything else in the lineup. The crackle texture dial is the detail that sets it apart from every standard diver: organic, complex, and genuinely beautiful under changing light. The yellow seconds hand and bezel pip are safety-inspired details borrowed from professional diving — high visibility in murky water. This is the most capable automatic in the range, and one of its most striking.
