Citizen Promaster NY0040-09W Diver's 200m Day Date Automatic Cal.8204 | 41mm

Citizen Promaster NY0040-09W — The Iconic Luminous Dial Automatic Diver

There's an unmistakable aesthetic to this Citizen Promaster NY0040-09W: the fully luminous lume dial, with that greenish-white hue that glows with extraordinary intensity in the dark, makes it instantly recognizable among thousands of divers. It's not just a functional choice — it's a powerful visual identity, loved by professional divers and enthusiasts worldwide.

The Promaster is Citizen's professional line, created for those who cannot compromise: precise instruments, built to withstand extreme conditions. The Japanese-made automatic caliber 8204, the case back engraved "DIVER'S WATCH 200M", the unidirectional bezel with a crown protected by characteristic integrated crown guards — everything about this watch speaks of technical seriousness and professional vocation.

This example was purchased in 2025 and shows minimal signs of use. The protective film is still applied to the case back. An exceptional opportunity to own a professional-grade diver at a fraction of the new price, with the complete original set.
