Water resistance ratings don't mean what you think.

🌊 THE REALITY

Ratings are tested in STATIC conditions. Real-world use involves DYNAMIC pressure which is significantly higher.

📊 WHAT YOU CAN ACTUALLY DO

  • 30m / 3ATM → Splash resistant only
  • 50m / 5ATM → Brief swimming
  • 100m / 10ATM → Swimming, snorkeling
  • 200m / 20ATM → Recreational scuba
  • 300m+ → Professional diving

⚠️ CRITICAL RULES

  • NEVER operate crown/pushers underwater
  • NEVER wear leather straps in water
  • NEVER take ANY watch into a hot tub or sauna
  • Water resistance DECREASES over time as gaskets age
  • Have gaskets checked annually if you swim with your watch
