Casio G-Shock GA-2100 (CasiOak) vs Citizen Tsuyosa Automatic

Buy the GA-2100 if you want a tough everyday watch you can swim, work and travel in without thinking about it. Buy the Tsuyosa if you want a traditional automatic dress watch with a steel case and sapphire crystal. The G-Shock wins on durability, water resistance and functions; the Tsuyosa wins on materials, finish and long-term ownership feel. Owners rate the Tsuyosa higher, but the GA-2100 is the more versatile of the two.

• Choose the G-Shock GA-2100 if you need 200 m water resistance, shock protection and alarms, timers and world time in one slim resin watch.
• Choose the Citizen Tsuyosa if you want an automatic steel watch with a sapphire crystal that works with a shirt and lasts for decades with servicing.
