​Iconic elegance and "Bullhead" design:
This superb Citizen from the 70s stands out for the imposing aesthetic of its bullhead configuration, a highly coveted arrangement by collectors due to the top placement of its pushers and crown, evocative of the era’s racing chronographs. The dial features a striking gold tone with a beautiful gradient finish, complemented by contrasting chronograph subdials at 3 and 9, applied indices, and an original-position double calendar window at 6, achieving a technical look and a strong presence on the wrist.

​The Mechanical Heart (Calibre 8110A):
Inside beats a legendary in-house automatic chronograph movement: Calibre Citizen 8110A with 23 jewels. It is one of the most reliable, robust, and advanced high‑vibration chronograph mechanisms ever built by the Japanese firm, featuring a column wheel and flyback function.

​Case, Pushers and Sculptural Design:
The movement is housed in a spectacular cushion‑shaped case with an angular profile, a sought-after architectural feature that gives the watch a visual strength and a wrist presence noticeably superior. It is paired with a brown leather Bund-style strap that enhances its classic and sporty character.

​Operation and Condition:
The watch is in generally operational condition with the following nuances: the quickset for the day and month works perfectly (confirming that the shared pusher and its return respond optimally). The start and the chronograph counter operate without issue. Regarding the chronograph reset, it does not consistently return the hand to zero and only rarely does so on its own; although, due to the mechanism’s nature, a cleaning and general servicing should restore it, it cannot be completely ruled out that an internal component may require inspection or possible replacement. As is typical with vintage mechanical watches that preserve authenticity and decades of history, if the future owner intends to use it daily with maximum precision, a classic factory service is recommended.

​Conclusion:
A magnificent opportunity to acquire an icon of Japanese watchmaking. The combination of a bullhead case reference 67-9143, a 23-jewel in-house automatic calibre 8110A in enviable conservation, and the strong visual impact of its gradient dial make this exemplar a must-have piece for any enthusiast or investor in high‑end vintage chronographs.
