These adaptors allow your apple watch to accommodate normal spring bars. The Zero-Pass design doesn't block sensors on the back of the watch like a normal pass-through strap.
ATTENTION: match your apple watch size with the correct adapter size and corresponding strap size:
Small apple watch: adaptor fits 20mm straps
Large apple watch: adaptor fits 22mm straps
Apple watch Ultra: adaptor fits 22mm straps
Your order comes with 2 adaptors and 4 spring bars.
