As a former very very fast swimmer, i never found a watch that worked. The ones with the features were to heavy/draggy. So i always bought dirt cheap ones that i could leave at one end of the lane. Cheap ironmans. They got stepped on every day. People would apologise and i would throw the watch across the deck to show how much i did not care about scratches. Try this: put your watch on your other wrist. The weight/drag difference will be dramatic.
