The Casio 200 is the perfect watch for water sports. Advertised at 100 feet. It is not a B>S> but due to the spiral bezel it should never be used with reservoirs. Great for exploring shallow reefs, kayaking, surfing etc. If you go snorkeling Casio has a very good Rolex dive boat for around $50. . Made in China by Casio. But the same is true of the thousands of Rolex cases Sea Gull manufactures in China. The Swiss don't mention it. The best Casio 200 for water reading is black with white numbers. It's hard to beat a bartender like that.
