This is some serious free diving action. William Trubridge for Suunto Watches Guillaume Néry for Ball Watches
Wow. The best I got up to was just over 2 minutes of swimming around (max depth 20-30 feet) I suspect much more serious training is required to break that threshold. Being able to do 2:10 and cover decent distance was still amusing for any bystanders who saw me dive down and not remerge.
