will my series 3 42mm watch bands fit the new apple 8

Hi happyDays75,

Thanks for posting here in Apple Support Communities. That's a great question. Your watch band may fit the Apple Watch Series 8 but it depends on the size of your current band. Use the following link as a reference: Change your Apple Watch band - Apple Support

Bands for 38mm, 40mm, and 41mm cases are compatible with each other, and bands for 42mm, 44mm, and 45mm cases are compatible with each other.

Bands for 49mm cases are compatible with 44mm and 45mm cases. Bands for 44mm or 45mm cases are compatible with 49mm cases.

Take care.
