Minimalist All-Black Design

The DW-5600UBB-1 takes one of G-SHOCK's most recognisable designs and strips it back to its essential elements. The matte black resin case, bezel and strap create a consistent monochromatic appearance, allowing the distinctive square shape to take centre stage.

Unlike conventional positive LCD watches, the DW-5600UBB-1 features a negative digital display with light-coloured characters against a dark background. This creates a seamless visual connection between the display and surrounding case, reinforcing the watch's understated, stealth-inspired appearance.

The result is a versatile design that works equally well with technical clothing, outdoor equipment and casual everyday wear. Its restrained styling makes it particularly appealing to users who prefer a practical digital watch without bright colours, unnecessary detailing or oversized proportions.

Legendary G-SHOCK Shock Resistance

The DW-5600UBB-1 retains the shock-resistant construction that established G-SHOCK's reputation for exceptional durability. Designed to protect the internal watch module against impacts and vibration, its robust structure makes it suitable for demanding everyday activities and environments where conventional watches may be vulnerable to damage.

The protective resin bezel helps shield the display from knocks, while the flexible resin strap provides a secure and comfortable fit. Mineral glass protects the LCD against the wear associated with regular use, contributing to a dependable design intended for long-term reliability.

Despite its rugged construction, the watch weighs just 53 g. This lightweight design reduces bulk on the wrist and makes it comfortable during extended periods of wear, whether working long shifts, travelling or participating in outdoor activities.

200-Metre Water Resistance

With 200-metre water resistance, the DW-5600UBB-1 provides dependable protection against water exposure during swimming, wet weather and recreational water-based activities. This substantial level of resistance makes it a practical choice for users who regularly encounter challenging conditions.

Combined with G-SHOCK's shock-resistant construction, the water-resistant design provides versatility across a wide range of environments. From everyday commuting and outdoor recreation to physically demanding work, the DW-5600UBB-1 is designed to remain reliable when exposed to the elements.

The watch should be used in accordance with Casio's water-resistance guidance, including avoiding button operation while submerged unless specifically permitted in the operating instructions.

Updated LED Super Illuminator

The DW-5600UBB-1 updates the classic 5600 Series design with modern LED backlight technology. Its white Super Illuminator provides illumination across the digital display, making it easier to check the time and access functions in darkness.

This is a practical improvement for users who frequently check their watch during evening activities, night shifts or in poorly illuminated environments. The afterglow function provides additional visibility immediately after the backlight has been activated.

The negative LCD complements the watch's all-black appearance, while the dedicated LED illumination helps maintain usability when ambient lighting is insufficient. Together, these features combine the distinctive styling of a dark digital display with practical illumination for everyday use.
