Is the Samsung Galaxy Watch8 LTE Classic thick for a 46mm watch?
At 10.6mm, thinner than 97% 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 Samsung Galaxy Watch8 LTE Classic?
Honor Watch 5 Pro - Bluetooth, Huawei Watch GT 6 - 46mm, Garmin Descent™ G2, Omega Seamaster Planet Ocean 600M Co-Axial Worldtimer 45.5 Master Chronometer GMT Ceramic / Black - Grey / Rubber all sit within half a millimetre of the Samsung Galaxy Watch8 LTE Classic's 46.4mm case, so they cover the same amount of wrist.
