The G-Shock Sand and Land collection draws its inspiration from the colors of sand and the earth's soil. Each model implements a slight camouflage design. The watches are created with a special process that takes two colors, then mixes and molds them into a unique color scheme for the case and strap. Models included are the digital GW-B5600SL-4 and GW-B5600SL-5 with features including Bluetooth, Tough Solar, and Multi-Band 6. The extra-large GX-56SL-4 includes Alpha Gel protection and Tough Solar as well.
