Citizen Record Label Tsuno Chrono PLAYGROUND Edition AN3660-73X – Limited Edition 4,000 Pieces

The Citizen Record Label Tsuno Chrono PLAYGROUND Edition AN3660-73X brings one of Citizen’s most recognizable vintage chronograph designs back with an unmistakably playful 1990s-inspired personality.

Produced as a worldwide limited edition of only 4,000 pieces, the AN3660-73X combines the retro-futuristic styling of Citizen’s legendary Tsuno Chrono — or “Bullhead” chronograph — with bold colors and a special luminous dial treatment that makes this model unlike the standard Tsuno Chrono lineup.

PLAYGROUND Edition – Limited to 4,000 Pieces Worldwide

Citizen designed the PLAYGROUND Edition around the colorful aesthetic of products from the 1990s, blending nostalgia with the unmistakable shape of its vintage chronographs.

The standout feature is its highly distinctive dial. Citizen applies luminous material across the dial and layers the colorful design over it, allowing the entire dial to develop a subtle glow after exposure to light.

In darkness, the dial itself appears to float and glow, creating an effect dramatically different from watches where lume is limited to the hands and hour markers.

Combined with its colorful accents, black detailing and retro case design, the AN3660-73X is exactly the kind of unusual Japanese-market Citizen that appeals to collectors looking for something outside the mainstream.

Iconic Tsuno Chrono Design

“Tsuno” translates to “horns” in Japanese, referring to the distinctive chronograph pushers positioned at the top of the case. This unusual arrangement gives the watch its characteristic Bullhead-style appearance and has become one of the most recognizable designs in Citizen's vintage-inspired catalog.

The compact 38mm stainless-steel case keeps the watch faithful to its retro roots while making it extremely wearable compared with many modern oversized chronographs.

Citizen pairs the case with a stainless-steel bracelet featuring an easily adjustable free-type clasp system.

Citizen Caliber 0510 Chronograph

Inside is Citizen's reliable Caliber 0510 quartz chronograph movement, providing excellent everyday accuracy and straightforward operation.

The chronograph measures elapsed time in 1-second increments for up to 12 hours, while a date display adds everyday practicality.
