ICE silicone wristwatch, black color. - Brand: ICE - Color: Black - Material: Silicone - Accessories: None - Style: Sport Attention!! This is a junk item. It probably doesn't work because the battery is dead. It's a screwdriver type, but it will probably open. I couldn't open it though... The glass on the dial is missing. The strap holder is also missing. For those who can repair it or want to study watches. Thank you for looking.
