Tam Nguyen 3 It is easy to absorb water in just a slide hand washing. Even the producer said this product is "daily use resistance" but at the first time I wash my hand with very slight atmosphere of water, the watch got wet inside then maybe because of that the hour marker also separated. When I contacted to the seller, they said, this watch is not recommended t wear while washing hand. I wonder, the producer should mention a list of daily life that we should and should not. Totally, I feel disappointed with both product and the producer.
