How to Choose a Watch Under $100
Movement type matters most
The biggest decision is automatic vs quartz. Automatic movements (like the Seiko 5 SNK803) are self-winding mechanical watches — no battery required, and they feel special to wear. Quartz movements (like G-Shock) are more accurate and more durable. If you want something special, go automatic. If you want something bulletproof, go quartz.
Water resistance: what the numbers mean
30M water resistance means splash-proof only — no swimming. 100M means you can swim with it. 200M means you can snorkel and dive. The Casio MDV106 ($59) and G-Shock DW5600 ($99) both offer 200M — exceptional at this price point.
Case size: bigger isn't always better
Most wrists suit a 38–42mm case. The Seiko 5 SNK803 and SNK809 are 37mm — slim and elegant. The G-Shock models are 43–45mm — bold and sporty. If you have a smaller wrist (under 7 inches), the Seiko 5 range is the better choice.
Trust Amazon reviews — but read them critically
Every watch on this list has 1,500+ Amazon reviews. The Casio MDV106 has 8,934. Look for reviews that mention long-term ownership (1+ years) and real-world use — those are the most reliable signals of quality.
