It seems like the larger screens are the only
consistent rumor for the Series 10.
Details like the exact size of the screens, thickness & features seem vague and contradictory. The 'thicker' CAD renders are from a source that previously revealed CAD renders of a
flat-sided Apple Watch which doesn't exist. Although they also got the Apple Watch ultra correct. A mixed bag to say the least.
Next Monday is the 10-year anniversary of the Apple Watch's announcement. Combined with the vagueness of the rumors and the perfect anniversary moment (remember, it was a surprise the event is on Monday rather than Tuesday) it does feel like there's a decent chance that it'll be a bit more interesting than the rumors say.
