Winding the crown by hand is perhaps a slight inconvenience, but an inconvenience nevertheless. Enter the watch winder, which spares you the trouble. These electronic objects come in a variety of shapes and sizes, but their underlying function remains the same. Often taking the form of a box, it does exactly what the name would suggest, rotating your automatic watch so as to keep the mainspring wound when the piece is not in use. As a result, you don’t have to turn the crown and reset the date and time every time you take the same watch out for a proverbial spin.
