mastermind Japan - Counting down to Valentine's Day but do not know what to get? How about a pair of matching watches? This V Day mastermind Japan and Casio have come together to bring you this unique box set of watches. Featuring two of G-Shock's most popular models, the DW-5600 and DW-6900, the watch colourways are largely influenced by black and mmJ's use of skulls. Nice. Get them at Colette.
