Ahoi

This watch cuts an exquisite figure on the beach, as the screw-down back and crown ensure it stays water-resistant—down to 200 meters. Ahoi also comes with an exceptionally elegant blue-black textile strap. An orange hand keeps track of the seconds and a splash of light blue makes playful references to the summer, while the luminous hands and indexes tell the time, even in the dark.
