Coke Bezel. Diver Chronograph. Watch Culture Icon.

The Alba AT3J37X is a men's Active quartz dive chronograph that wears one of watchmaking's most celebrated bezel colourways. The black and red "Coke" bezel — black on the left, vivid red on the right, triangle pip at 12 — is an icon borrowed from professional diving and made famous on the world's most desirable sport watches. On the AT3J37X it frames a deep matte black dial with three tone-on-tone sub-dials and a single red chronograph centre seconds hand that ties the bezel colour to the timing function. At 45mm this is a watch that commands the wrist. A 60-minute chronograph accurate to 1 second, 24-hour indicator, and 100M water resistance back every detail with genuine capability. Japan movement backed, Seiko quality assured.

Why You'll Love It

The AT3J37X is a watch for people who know their watch culture. The Coke bezel is not a random design choice — it is a deliberate reference to one of the most celebrated bezel colourways in the history of sport watches, typically found on watches at ten times this price. Alba has brought that reference to a 45mm chronograph with 100M water resistance and a VD53 quartz movement, at a price that makes it genuinely accessible. The red seconds hand connecting to the red bezel half is the kind of considered design decision that watch enthusiasts notice. A natural companion to the AT3J43X black dial version for those building the AT3J collection.
