As the 45mm Galaxy Watch3 in Mystic Black rotates, it turns into a 45mm Galaxy Watch3 in Mystic Silver with an Analog Modular watch face. It continues rotating and turns into the 41mm in Mystic Bronze with the Female Classic watch face. Once it stops, multiple Galaxy Watch3’s with different watch faces appear to show all the different combinations.

Outlined in a subtle rotating bezel, it's easier to see and focus on what matters with an even bigger screen. Galaxy Watch3 is thinner and lighter than its predecessor, with a sophisticated look and slimmed down frame.
