Water-Resistant fabrics shed water because of their weave or because they have been treated. They will soak through in a heavy rain, however.
Water-Repellent fabrics are more effective than water-resistant fabrics. They are either very tightly woven or coated with a finish that causes the water to make little beads when it hits the fabric rather than going through.

Water-resistant is a fabric or thing like watches which is able to resist the penetration of water to some degree but not entirely.....
Water-repellent means not easily penetrated by water, especially as a result of being treated for such a purpose with a surface coating

Water repellant and water-resistant are terms used to describe degree at which a material will be able to withstand being saturated by water. These two terms are often compared to the term "waterproof." Typically, water-resistant is the lowest rating, while a material that is water repellant is likely to be of greater use when more water exposure occurs. Something that is waterproof may remain undamaged by significant contact with water, but even here, there may be a limit to how much liquid exposure the item can take.
