You should clean the watch using fresh water after the swimming in the ocean:
...
Clean Apple Watch if it comes in contact with anything that may cause stains or other damage, such as dirt or sand, makeup, ink, soap, detergent, acids or acidic foods, or comes in contact with liquids other than fresh water, including those that may lead to skin irritation such as sweat, salt water, soapy water, pool water, perfume, insect repellent, lotions, sunscreen, oil, adhesive remover, hair dye, or solvents. The Apple Watch and band colors may vary or fade over time.
After swimming with Apple Watch, gently rinse it with warm tap water.
