Description

The Citizen AN3660-73X is a striking 2026 release within the Record Label Playground Edition, reviving one of the most iconic silhouettes in watch history. Famously nicknamed the "Bullhead" or "Tsuno Chrono" (meaning "Horned Chrono" in Japanese), this JDM model is a modern quartz reimagining of the 1973 Challenge Timer. It features a period-correct 38mm Stainless Steel Case with the crown and chronograph pushers uniquely positioned at the 12 o'clock mark, a design originally intended to prevent pushers from digging into the wrist while providing a "stopwatch" feel during operation.This specific edition is often called "The Luminous Brothers" green variant, featuring a vibrant Mint Green Dial that is fully coated in luminous paint. This specialized "Playground" finish allows the entire dial to glow in low-light conditions, contrasted by bold black sub-dials and high-visibility orange chronograph hands. As a Limited Edition of 4,000 pieces worldwide, it balances its 1970s "retro-futuristic" aesthetic with a highly functional layout, including a tachymeter scale for speed calculations and a date window at the 4:30 position. The watch is protected by a Mineral Crystal and is finished with a brushed stainless steel case that maintains a slim 11.7mm profile.Powering the AN3660-73X is the reliable in-house Citizen Caliber 0510 Quartz Movement. This 1-second chronograph can measure elapsed time up to 12 hours, offering the grab-and-go accuracy of quartz while staying true to the mechanical "Bullhead" proportions. It comes equipped with a vintage-style Stainless Steel Men's Watch bracelet featuring a fine-pitch multi-link design and a sliding clasp for tool-free size adjustments. With 50-meter water resistance, this timepiece is a durable, collectible tribute to Citizen’s avant-garde heritage.
