Bloomberg's Mark Gurman wrote in his latest newsletter that the upcoming smartwatches will come in 41mm and 45mm sizes. His sources claim that there will be several exclusive and new watch faces to take advantage of the bigger screen sizes which include a refreshed Infograph Modular face.
Gurman added that this year's upgrade will focus on the new design and a faster chipset. Next year's smartwatches may come with a body-temperature sensor. Other rumoured specs of the Apple Watch Series 7 include a bigger battery and new colours.
