Casio G-SHOCK The Origin Watch DW-5600BCE-1ER

Introducing the Casio G-SHOCK DW-5600BCE-1ER, the most austere and tactical version of the square that started it all. The octagonal matte black resin case absorbs light without giving back any glare: the upper bezel is marked with the "PROTECTION" inscription, the lower bezel carries the embossed "G-SHOCK" logo, and four guard screws at the lower corners reinforce the military aesthetic. The sides display ADJUST, MODE, START/STOP, and LIGHT pushers labeled in thin white typography, nearly invisible against the black. The strap is ballistic nylon textile sewn onto a resin base, visually setting this model apart from standard rubber-strap DW-5600s and giving it a more utilitarian, urban character.

The light-background LCD display contrasts with the total darkness of the exterior and organizes information across two clearly differentiated levels. The upper strip shows the abbreviated day of the week on the left alongside alarm and time signal icons, and the date in month-day format on the right inside a box. The central strip, featuring large digits, displays the time in 12-hour format with a PM indicator and a sun-shaped light icon to the right. Module 3525 delivers: full time and auto-calendar, an alarm with hourly time signal, 1/100-second stopwatch with 24-hour capacity and split function, and countdown timer with auto-repeat, with the calendar programmed through 2099. The LED backlight turns on with the LIGHT button and fades out gently thanks to its afterglow.

G-SHOCK was born in 1983 by engineer Kikuo Ibe with one radical goal: to build a watch that could survive a free fall from 10 meters. The DW-5600 series is the direct descendant of that first prototype, preserving the original square silhouette that defined the visual language of the entire family. Decades later, it remains the reference against which all others are measured: triple-layer shock protection structure, high-density resin, reinforced mineral crystal, and a hermetic seal for 200 meters of water resistance. The BCE variant features the textile strap as its tactical signature, adopted by users who demand durability and discretion in equal measure.
