Key Takeaways. The GLX‑S5600 is a sleek, surf-ready square G‑Shock featuring tide and moon graph support, 20-bar water resistance, eco-conscious bio-resin, and strong illumination — all in a compact sub‑42 mm case priced under $100. It’s perfect for smaller wrists and coastal use. However, it lacks solar or Bluetooth, uses a replaceable battery, has a small interface, and may not fit larger wrists comfortably.

PROs
Tide & moon-graph display – Great for surfers and ocean lovers with intuitive moon age icons.
Compact, slim profile – At 45.7 × 40.5 × 11.9 mm and 41 g, it’s ideal for smaller wrists and more discreet wear.
Eco-friendly bio-resin case/band – Sustainable materials reduce environmental impact.
20‑bar water & full shock resistance – Meets ruggedness standards of G-Shock, with added surf-ready depth rating.
Super Illuminator auto LED – Bright backlight with wrist-tilt activation for easy night visibility.
World time across 48 cities – Useful for travel and international time checks.
Full stopwatch & countdown timer – Features 1/100‑sec chronograph and 24‑hour repeat timer.
Three alarms with snooze & flash alerts – Versatile audible and visual notifications.
Affordable (~US $99) – Solid functionality and coastal style at a good price.
CONs
Mineral crystal only – More prone to scratches compared to sapphire glass.
Modest 3‑year CR1616 battery life – Similar to standard digital models; no solar power.
Timer only in 1‑minute increments – Less precise than similar models like GMD‑S5600.
May fit only wrists ≤5.5″ – Sharp lug angle limits comfort on larger wrists.
No Bluetooth app sync – Lacks automatic time sync or smart features.
Basic interface & small digits – Tiny display can feel cramped and harder to read.
No vibration alert – Flash only for alarms and signals — no haptic feedback.
Limited battery compared to GLX-5600 – Lacks 7-year battery life in larger variants.
Gender-targeted marketing – Branded under women’s/kids line, which some male users find less appealing.

Enjoy Japanese Unique Features in GLX-S5600!
Nostalgic color inspired by surf beach.
Pale blue (GLX-S5600-3) and pale orange (GLX-S5600-4). Under the theme of nostalgic beach, we adopted a fade color that goes well with surf fashion. The faded tones and matte textures create a cool, retro feel. Two models, basic black (GLX-S5600-1) and off-white (GLX-S5600-7), are also available.
Compact & Slim.
Compared to the regular size GLX-5600, the case size (horizontal) has been reduced to about 94%. The thickness has been reduced and the fit has been improved. It is easy to wear even for women and people with thin arms, expanding the range of coordination.
Biomass Plastic.
Biomass plastic is used for the bezel and band. By using renewable organic resources as raw materials, we contribute to reducing environmental impact. We have created a symbiosis with nature by uniting the thoughts of everyone who loves the sea.
Various functions useful for surf riding.
In addition to the shock-resistant structure that can be used hard and water resistance of 20 bar, it is equipped with tide graph and moon data. Useful for marine sports such as surfing.
Super illuminator for easy viewing even in dark places
