The only diffrence is in looks and price. Mechanically they use the same movement. The premium model was introced a couple of years prior to the supreme model. Hope this helpsHi guys, I've been eyeing the Sourab range for a while now. Can someone please explain the difference between Sourab Premium and Sourab Supreme? The Supreme variant is back in stock on the official website, but I have a slight preference for Premium's looks. Wondering if it makes to wait.
