Timeless elegance is paired with highly refined, precious materials, slim shapes and understated straps. Choose a dress watch for a look that will effortlessly pair with a tuxedo. Look out for a wristwatch that will comfortably slide under the cuff of a shirt and jacket. Some experts recommend pairing the colour of the dial with the time of day of the formal event. Blue and black for evening and night, lighter hues for the day.
