Can I swim with the stainless steel band on my Apple Watch 2?

Hi

No - the Link Bracelet is not water resistant, so should not be exposed to liquids or worn when swimming with Apple Watch Series 2.

Leather bands are also not water resistant. Other bands are available to buy as separate accessories. The Sport Band, for example, can be worn when swimming and then cleaned and fully dried immediately afterwards, ready for ongoing wear:
