A rumor Thursday claims that bands for Apple's next-generation Apple Watch will be incompatible with current models, though it isn't clear if old bands will work with the new watches.
In August, leaker "Uncle Pan" suggested "Apple Watch Series 7" will come in 41mm and 45mm case sizes, a 1mm increase over today's models. Subsequent reports have reiterated those claims, but questions about the wearable's specifications remain.
While a larger chassis is expected to facilitate bigger screens and, potentially, more capacious batteries, the shift could make existing band and strap accessories obsolete, at least for upgraders.
"Uncle Pan" believes "old" bands will fit the new models, but didn't mention compatibility between "Apple Watch Series 7" bands and previous Apple wearables. However, on Thursday, a new rumor from leaker Max Weinbach appears to suggest that new bands won't fit old Apple Watch models.
"[For what it's worth] I've heard from an Apple store employee that they're not getting anymore 40/44mm bands in and expect the new Apple watch to use different bands that won't be compatible with old watches," Weinbach said in a tweet.
The assertion is questionable at best, as Apple Store employees are typically not informed of the company's future product plans. Additionally, a 1mm size increase is negligible, so the incompatibility would likely stem from a case redesign.
That said, a pair of leaks last week claim to show bands for as-yet-unannounced 41mm and 45mm Apple Watch models. Whether the supposedly unreleased bands fit current devices is unclear.
Apple Watch currently comes in 40mm and 44mm case sizes, dimensions that were last changed when the device grew from 38mm and 42mm with "Apple Watch Series 4" in 2018.
"Apple Watch Series 7" is expected to debut alongside "iPhone 13" at a special event this fall.
Update: A previous version of this story suggested that old Apple Watch bands wouldn't fit the "Apple Watch Series 7."
