Alba 5Y66 is a wristwatch with a variety of features that can be useful in everyday life. It displays the time in 12 or 24-hour format, the day of the week and the date. The day of the week hand moves in a fan-like fashion, and the 24-hour hand works in conjunction with the hour hand. To set the day of the week and time, first set the day of the week by turning the hour and minute hands. Then set the time, making sure to set it correctly to avoid setting a.m. and p.m. in error. To set the date, pull out the crown to the first click and turn it counterclockwise.
