Casio G-Shock DW-5600 vs Casio G-Shock GM-2100

The DW-5600 is the tougher, simpler, cheaper-feeling classic: a 54g resin square that survives drops and swims, with a 2-year battery and a proven 1980s design. The GM-2100 is the step up in looks and materials, with a stainless steel bezel, analog hands with Neobrite lume, a slimmer 11.8mm case and a 3-year battery. Reviewers and owners praise both for durability; the GM-2100 draws more comments on its dressier look and slightly harder-to-read analog face, while the DW-5600 is the one people call indestructible and forget about.

• Choose the DW-5600 if you want the lightest, most bombproof digital beater for the gym, water and rough work, and you don't need analog hands.
• Choose the GM-2100 if you want a G-Shock that looks good with a jacket, with analog hands, lume and a steel bezel, and you're fine with a heavier, larger watch.
