Apple almost always launches the latest Watch range alongside the latest iPhone. That means we should almost certainly see it in the second or third week of September, barring any exceptional circumstances.
Apple follows a consistent launch schedule, so it’s been predicted we’ll see the new Apple Watch on the 6th or 13th September 2022.
Plus, if the dates go to plan, the Series 8 range should be available to buy at some point in October 2022.
