The Apple Watch Series 7 debuted at the big September 14 hardware event, with a vague “fall” release date. Today, the company announced that the popular wearable will go up for preorder this Friday (October 8), with in-store available starting a week later, on the 15th, for customers in Australia, Canada, China, France, Germany, India, Japan, Mexico, Russia, South Korea, UAE, UK and US.

The most notable addition here is a display that’s 20% larger than its predecessor, capable of fitting 50% more text. The screen is brighter as well, and fortified by stronger crystal, with the watch now sporting an IP6X rating for dust, coupled with the existing WR50 water rating for swimming. Contrary to rumors, the overall battery life hasn’t improved (rated at 18 hours), but charging is now 33% faster.
