It is compatible with all the latest Apple Watch Series 8, 7, 6, SE, 5, 4, 3, 2, 1. To confirm your watch size, just check the backside of your watch. You can find the correct size from any of 45mm 44mm 42mm 41mm 40mm or 38mm.
I liked it, it looks like it's made of stainless steel, obviously it comes wide in case your wrist is bigger than mine, but by removing links it fits well.
