When it comes to Citizen’s most iconic watch series, the Alarm series easily earns its place at the top. Citizen has long been a pioneer in Japanese watchmaking—introducing the country’s first calendar watch in 1952, its first shock-resistant watch in 1956, the first alarm wristwatch in 1958, and Japan’s first water-resistant watch in 1959. Each was a bold step forward, but it was the Parashock, Citizen’s answer to shock resistance, that truly caused a stir across Japan.

Now, imagine blending two seemingly contradictory worlds: A diver’s watch and an alarm complication. Not exactly a pairing you’d expect, but that’s exactly what makes it brilliant. Citizen took a chance, and the result was the striking and rare Citizen Alarm Date Diver ALDS 52902-Y, a diver that defies expectations and delivers a hefty dose of retro charm.

Limited in production and bold in character, this unique diver stands out with a glossy black dial, a bi-directional rotating bezel, and a vibrant red alarm hand that’s impossible to miss. But here’s the twist: instead of the usual bezel marker, the signature red triangle belongs to the alarm hand, adding a clever and unconventional visual cue that sets it apart from typical divers of the era.

The finishing details are nothing short of hypnotic. A deep black, mirror-like bezel insert frames the dial with a sleek intensity, playing beautifully against the ultra-glossy finish beneath the crystal. Light dances across the watch’s clean, sharp surfaces, giving the impression it just left the factory floor. And in this case, that’s not far from the truth: This example is stunning, recently serviced and ready to wear. If you missed out on the last one we sold, here’s your second chance to snag this stunning piece. We’ve paired it with a beautiful set of suede leather straps from Accurate Form to stay in line with the dive heritage of this model.

Powered by the Cal. 3102, based on the reliable A. Schild architecture, the Alarm Date Diver is more than just a handsome face. It’s a reminder that sometimes, the most surprising combinations, like a diver with a built-in alarm, can lead to the most memorable creations.
