Don't Wait if You Find Something You Like
If you're shopping for a new smartwatch and you see something that you like, whether that's one of Apple's Watch models or an alternative like the Samsung Galaxy Watch 3 or the Fitbit Versa 2, don't let Apple Watch 7 rumors hold you back.
If you find a good deal and or you're able to cheaply upgrade from an older model, it makes more sense to get the upgrade you want right now and enjoy it for the next year or more.
You can always sell an Apple Watch for a decent amount on the resale market to pay for part of your Apple Watch 7 upgrade later on.
This is a good reason not to wait for the Apple Watch 7, especially with the release as far out as it is.
