Prospective customers should stop buying the Apple Watch Series 3 because it won't run the latest version of Apple's watchOS software.

Almost five years have passed since the release of the Apple Watch Series 3. The oldest device to support the latest version of watchOS 8 is the S3 chip, which lags behind Apple Watch Series 7 and the S5 chip. The Apple Watch Series 3 is the only remaining Apple Watch that has an older, thicker design.

When updating watchOS, Apple Watch Series 3 users have to unpair and re-pair the device from their linked phone because the Apple Watch does not have enough internal storage.

The next-gen operating system for the Apple Watch was shown off in June. The Apple Watch Series 3 will no longer be supported by the new OS. The Apple watch series 3 is still on sale. Potential customers shouldn't buy the device since it won't support the latest version of watchOS when it is discontinued by Apple.

Those looking for a low-cost Apple watch should wait for the second generation. The Apple Watch SE was a low cost option for customers. The Apple Watch SE is expected to be replaced by a second- generation model next month, as it nears two years since launch, according to sources.

Gurman says that the Apple watch may have the "S8" chip. Apple could upgrade the Apple Watch SE to its latest processor if the S8 chip features the same specifications as the S6 and S7 chips. It won't make a difference if you have the S6, S7, or S8 because all of the chips that are newer than the Apple Watch SE's current processor are essentially the same.

The new Apple Watch will almost certainly support the latest version of watchOS for longer, so buyers looking for a low-cost Apple Watch should wait until the new model arrives.
