The Ndur Watch Band Compass is ultra lightweight. It's compact and fits most watch bands. it is complete water proof. It features a liquid filled compass and weighs only 0.2 ounces. Made in Taiwan.
Poorly glued. Fell out in like 2 days. I would recommended removing and glueing it in yourself with epoxy. Works good enough for Cardinal direction finding.
So ya...This item lasted a whole 7 hrs on my wrist before the glue let go and I had to search for the compass.. Cheers!
