The correct adjustment method, consistent with the genuine product, is done via the second time zone, which is displayed through a sub-dial. This sub-dial consists of two elements: a red triangle located below the logo, indicating the time of the second time zone in a 24-hour format. Pulling the crown out to the first position allows for the adjustment of the calendar; pulling it up adjusts the calendar, while pulling it down adjusts the hour hand (the minute hand remains stationary). Pulling it to the second position allows for normal time adjustment (the 24-hour sub-dial bezel moves accordingly).
