Watch Water Resistance Explained: 50M, 100M and 200M

The number on a watch dial, such as 50M, 100M or 200M, is easy to misread. It does not mean you can dive to that depth.

What the rating means

Water resistance ratings come from laboratory pressure tests, not real-life activity. Movement in the water, such as swimming or a splash from a wave, creates more pressure than standing still, so a watch needs a safety margin for real use.

A simple guide

• 50M: suited to everyday life, such as rain, splashes and washing your hands. Not made for diving.
• 100M: a stronger margin for swimming and water play.
• 200M: built for water sports and more demanding use, such as our Invicta Pro Diver watches.

Tips to protect your watch

• Make sure the crown is pushed in or screwed down fully before it touches water.
• Do not press buttons or pull the crown underwater.
• Rinse with fresh water after the sea or a pool, and dry it.
• Seals age over time, so have water resistance checked if you use your watch in water often.

Always follow the manufacturer's guidance for your exact model. Browse our dive and field watches to see options.
