What size band does the Amazfit GTR 4 take?

Is the Amazfit GTR 4 thick for a 46mm watch?
At 10.6mm, thinner than 98% of 46mm watches, so it slides under a cuff more easily than most of its size. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.
What other watches are the same size as the Amazfit GTR 4?
Honor Watch 5 Pro - Bluetooth, Huawei Watch GT 6 - 46mm, Samsung Galaxy Watch8 LTE Classic, Garmin Descent™ G2 all sit within half a millimetre of the Amazfit GTR 4's 46mm case, so they cover the same amount of wrist.
