A braided elastic strap with magnetic closure for the BLOK 33. Magnetic latch, no pin and no holes to line up Universal wrist fit up to 8 inches, set by latch position 300D braided nylon woven over an elastic core Simply pass through the fixed lugs with no tools and no spring bars 17mm for the BLOK 33 A watch a child cannot fasten is a watch a child does not wear. The BLOK has fixed run-through lugs, so nothing to pry, nothing to lose on the kitchen floor. Once it is on the watch the magnetic latch does the rest. The magnet force is perfectly balanced - easy enough to open, but secure enought to play, with two locator pins stopping it from sliding apart. The latch allows almost universal fit - up to 8 inches (and beyond with a bit of stretch). There is no set of holes deciding for you, so you put it where the wrist actually sits, and when the wrist grows you move it. One strap, the whole way through, from a four year old to an adult. The band is woven from 300D braided nylon over an elastic core. Polyester yarn filaments run through the weave to stop it going slack after a summer of being pulled on and off. It breathes, it dries, and it stays soft against skin that will not tolerate much else.
