Full Black PVD. Automatic Diver. Stealth at Its Finest.

The Alba AL4483X is a men's mechanical automatic diver watch built entirely in the dark. The full black PVD case, rotating dive bezel, crown and bracelet create a seamless stealth exterior that absorbs light rather than reflecting it — a blacked-out presence on the wrist that means business. The deep black dial carries oversized luminous circular dot hour markers, a bold inverted triangle marker at 12, and arrow-shaped luminous hands designed for one thing: maximum readability in darkness. Powered by the Japan-made Y676 automatic calibre, self-winding and battery-free, with a rotating unidirectional dive bezel and 100M water resistance. Japan movement backed, Seiko quality assured.

Why You'll Love It

The AL4483X is the watch in this collection that collectors call a "stealth diver" — a full black PVD automatic with dive credentials and mechanical soul. The category has devoted followers who understand that blacking out an automatic diver is not just an aesthetic choice, it is a statement of intent. Every component — bezel, case, crown, bracelet — is treated to the same black PVD finish, creating a monolithic, unified presence that silver and two-tone watches simply cannot match. The oversized lume dots and arrow hands ensure it performs as well in the dark as it looks in any light. The most intense watch in the Alba Mechanical range, and the one most likely to generate a conversation.
