May 08, 2026, 8:37 AM

Citizen has re-envisioned its renowned 'bullhead' chronograph, introducing the Challenge Timer 'Tsuno' to a new generation of enthusiasts. This model, deeply rooted in 1970s watchmaking heritage, features the distinctive crown and pushers positioned at the top of the case, reminiscent of classic stopwatches. The new iteration, powered by a modern quartz movement, offers a blend of vintage aesthetics and contemporary practicality, all at an inviting price point.

This revival is particularly significant given the enduring appeal of the original 'bullhead' design, famously seen on the wrist of Brad Pitt in a recent film. By opting for a quartz movement, Citizen has made this historically inspired timepiece more accessible, democratizing a design that was once exclusive to Japan. The new Challenge Timer 'Tsuno' is a testament to Citizen's commitment to preserving its legacy while embracing innovation, providing an affordable yet authentic vintage-inspired watch for a diverse global market.

The Reimagined Citizen Challenge Timer "Tsuno"

Citizen's latest Challenge Timer "Tsuno" chronograph pays homage to its 1973 predecessor, faithfully maintaining the original's distinctive design and compact 38mm stainless steel case. This meticulous recreation ensures that the new model captures the essence of its vintage inspiration, a detail that will resonate with collectors and enthusiasts who appreciate the authentic heritage of the "bullhead" style. The nickname "Tsuno," meaning "horn" in Japanese, aptly describes the unique placement of the pushers and crown at 11 and 1 o'clock, a configuration that not only defines its iconic appearance but also enhances the watch's ergonomic functionality, allowing for effortless operation of the chronograph features.

The integration of an in-house quartz caliber 0510 into this new release represents a strategic move by Citizen to make the "bullhead" design more attainable. This modern movement provides accurate timekeeping with a ±20 seconds per month variance and includes a chronograph function capable of measuring up to 12 hours with one-second resolution, alongside a date display at the 4:45 position. Available in a classic white panda dial with black sub-dials and a limited-edition luminous green variant, both featuring orange accents on select hands, the Challenge Timer "Tsuno" is designed to appeal to a broad audience, offering a historically rich timepiece without the complexities and higher cost associated with mechanical vintage watches.

Design and Wearability: A Nod to the Past, Built for the Present

The aesthetic of the new Citizen Challenge Timer "Tsuno" immediately transports the wearer back to the 1970s, thanks to its well-preserved proportions and design elements. The 38mm diameter and 11.7mm thickness contribute to a compact and comfortable fit, echoing the feel of vintage chronographs. While the pebble-shaped case, paired with a slender stainless steel bracelet featuring folded links and a sliding clasp, creates a slightly top-heavy sensation, it remains remarkably comfortable on the wrist. This unique wearing experience, though different from conventional bracelet watches, adds to the watch's distinctive character, offering a lighthearted and fun accessory that stands out.

Choosing between the standard panda dial and the limited-edition full-lume teal version presents a matter of personal taste. The panda dial exudes a more classic and refined appeal, providing a sophisticated vintage feel that many enthusiasts seek in a "bullhead" chronograph. In contrast, the luminous green dial offers a more vibrant and bold statement. Despite minor details like the date window placement at 4:45, which could arguably be repositioned for better visual balance, the Citizen Challenge Timer "Tsuno" delivers exceptional value at its €229 price point. It successfully blends historical design with modern reliability, making it an attractive option for those desiring a unique and accessible vintage-inspired timepiece.
