Hello @MJAdams and welcome to the Community. No, they don't. The 24 mm bands are for the Sense/Sense 2/Versa 3/Versa 4. My advice is go directly to the Google Store to buy your Fitbit branded accessories. They are clearly marked by model. If you start a purchase in the Fitbit Store, you get directed to the Google Store to complete your purchase. Just start in the Google Store. Third party bands are usually clearly marked by device.
