The G-SHOCK DW-5600MNC Series is the first official collection from Casio to feature a factory-installed FIDLOCK® magnetic buckle system. This fastening technology, frequently utilized in high-end technical apparel and cycling gear, uses magnets to guide the clasp into position before a mechanical lock secures it. The watch utilizes a specialized stretch cloth band made from a polyester and polyurethane blend that can expand up to 2.7 times its original length. This elasticity allows the watch to be worn directly on the wrist or over the sleeve of a jacket during outdoor activities.

The series maintains the classic "square" proportions with a case length of 48.9mm and a width of 42.8mm. It features a slim profile with a thickness of 13.4mm, designed to sit low on the wrist even when worn over clothing. Despite the addition of the magnetic hardware and cloth strap, the watch remains lightweight at 53 grams. The band is adjustable to accommodate wrist circumferences ranging from 145mm to 215mm, offering a broader fit range than standard resin straps.

Internally, the series is powered by Module 3525, a reliable digital quartz movement that provides a 5-year battery life. The bezel and case components are constructed from bio-based resin to reduce environmental impact. The watch is built to G-SHOCK's shock-resistant standards and features a 200-meter water resistance rating. For low-light visibility, it includes a white LED Super Illuminator with a customizable afterglow, ensuring the digital display remains legible in total darkness.
