Apple will potentially launch the iPhone 13 series along with the redesigned Apple Watch Series 7 later this month. While no event invites have been sent out so far, we presume Apple will host the event in the second half of September. Nonetheless, the Apple Watch is coming with a refreshed design this year and the company is also running into production issues due to the complex redesign. The flat-edged design of the Apple Watch Series 7 will give Apple more room to include a larger display. However, how big would the display be compared to Series 6 and Series 3?

The Apple Watch Series 7 will feature the biggest screen size on any Apple Watch with 41mm and 45mm. However, if you are looking to upgrade to the forthcoming model, you should know how big the display size will be compared to the previous models. 9to5mac has designed some mockups that show the Apple Watch Series 7 display size in comparison to the Apple Watch Series 6 and Series 3.
