WATER RESISTANCY
Nixon guarantees the water-resistance of your Diplomatic watch
to a rating of 200 METERS.
Before contacting any water it is critical that your crown is screwed
in completely to ensure complete protection.
Please know that the water resistancy is attained using a series of seals which will
deteriorate under normal conditions and reduce the water resistancy of your watch.
These seals should be checked by Nixon or a certified watch repair shop at least once
every two years to ensure the rated water resistancy.
Avoid wearing your Diplomatic in hot tubs or saunas.
