Which Bands Fit Apple Watch Series 10? (2026)

Warning: The 42mm Confusion
The 42mm Series 10 is in the Small Group, but the original 42mm (Series 1-3) is in the Large Group. Despite having the same case measurement, their band connectors are completely different. If you are upgrading from a Series 1-3 (42mm), your old bands will NOT fit the Series 10 (42mm).

Does Apple Watch Series 10 use new bands?
Series 10 introduced new case sizes (42mm and 46mm) but the band connectors are the same as previous generations. The 42mm uses small group connectors (same as 38/40/41mm) and the 46mm uses large group connectors (same as 44/45/49mm).
Can I use my old Apple Watch band on Series 10?
Yes! If you had a 38mm, 40mm, or 41mm band, it fits the 42mm Series 10. If you had a 42mm (Series 1-3), 44mm, or 45mm band, it fits the 46mm Series 10.
Are 42mm Series 10 bands the same as 42mm Series 1-3 bands?
No! This is a common mistake. The 42mm Series 10 is in the SMALL group (same as 38/40/41mm), while the 42mm Series 1-3 is in the LARGE group (same as 44/45mm). They are NOT interchangeable.
