In 2005, A. Lange & Söhne released the Lange 1 Time Zone ref. 116.025 featuring a dual time complication with a city ring, its iconic asymmetrical Lange 1 dial layout charmed with its signature large date. Practical and simple to operate, the Lange 1 Time Zone differs from your usual dual time wristwatch which features the much “easier” additional hour hand to depict the second time zone. However, the German powerhouse decided to finesse the dual time wristwatch showcasing the additional time zone in an entirely separate dial. Fitted with a city ring that is activated via a pusher at 8 O’clock, once pressed, the additional time zone adjusts itself to the city indicated by an arrow positioned on the dial of the additional time zone at 5 O’clock.
