In 2016 Rolex unveiled a bulgy Air-King watch, a watch that has used conservative 34mm oyster case throughout its long history. The air-king has grown significantly, by 6mm, and now comes with a
replica rolex 40mm case (not to mention a completely redesigned dial and anti-magnetic properties). Then, at Basel world in 2017, things got really crazy, when the Sea-Dweller got bigger and went from a 40mm case to a new 43mm one. With Rolex releasing a two-tone version at Basel world in 2019, the 43mm sea dweller looks set to stay.
