Citizen Bullhead AN3660-81L Record label Tsuno

The 2021 Citizen Tsuno Chrono AN3660 - 81L is a revival of Citizen's highly sought - after vintage bullhead - cased Chronograph Challenge Timer. Officially named Tsuno Chrono, with 'tsuno' meaning 'horn', this watch brings back the classic charm. It features a cool blue dial set in a 70s - style stainless - steel case and bracelet, giving it a strong vintage feel. The dial shows the date and 12/24 - hour time. Powered by advanced quartz precision timekeeping, the chronograph can accurately measure up to 60 minutes in one - second increments. With a Calibre 0510 quartz movement, it offers an accuracy of ±20 sec / month. The 38.0mm case, 11.7mm thick, has a push - button clasp and is protected by spherical mineral crystal glass. It's also 50 meters water - resistant, making it suitable for various daily activities.

Using your Citizen Tsuno Chrono AN3660 - 81L is easy. To set the time and date, use the crown on the side of the watch. Pull it out gently to different positions to adjust the time and date as needed. The chronograph function is great for timing events. Press the top button to start, the bottom button to stop, and the top one again to reset. When it comes to taking care of your watch, keep it away from strong magnetic fields as they can affect the accuracy. Also, avoid exposing it to extreme temperatures. To clean it, use a soft, dry cloth. If you get it wet, make sure to dry it thoroughly. And since it's 50 meters water - resistant, it can handle splashes and short swims, but don't wear it for deep - sea diving.
