While Apple may only be a few months away from releasing the Watch Series 6, hardly any reliable leaks about the smartwatch have surfaced online. Presumably launching on watchOS 7, there have been rumours of the Watch Series 6 supporting an "underwater mode", Touch ID and a blood oxygen monitoring.
In place of more information, ConceptsiPhone has imagined how the next Apple Watch could look if Apple tweaked its display, too. The Watch Series 5 retains the 1.53 and 1.78-inch displays of its predecessor, so we would not be surprised if Apple introduced new display sizes for the Watch Series 6.
As ConceptsiPhone has demonstrated with their renders, reducing the size of the bezels on the Watch Series 5 would give its successor a more modern look. There is no indication that Apple plans to release a bezel-less Watch Series 6, but the renders that ConceptsiPhone has created are captivating, nonetheless.
Apple is expected to launch the Watch Series 6 alongside the iPhone 12 series in Q3 2020. Possibly going ahead in September, watchOS 7 should be revealed in advance at WWDC 2020 in June.
