I am very satisfied with this watch from Madison NY. There is a cheaper version of the famous brand watch Ice Watch Sili Forever White Small 38mm.
The Madison costs 29,95EUR with only half as much as the brand watch above. I find the price for the quality of the clock and adequate for normal swimming in the sea, the clock has proven with 5ATM as waterproof. (Unsuitable for diving) The housing, the hands and the numbers on the dial glow in the black light that looks cool in the disco.
