Key Takeaways The DW‑6600 is a rugged, no-frills G‑Shock classic — a lightweight, military-grade watch with one of the first EL backlights and a reliable 5-year battery. Its vintage era charm and durable build make it a cult favorite, especially among SEAL-lovers. Yet it remains basic: no solar, no atomic, no smartwatch features, and a chunkier mineral-crystal body that feels dated in today’s feature-rich landscape.
