Love the Casio's being shown. Nice.
I own 3 Casio's and all of them are rated 100-200m.
But,,,,Any 100m WR watch will suffice for swimming.
Lets just say the list of 100m rated watches is endless.
Where do we start ? So many brands to choose from.
My favorite is a Seiko Solar 100m WR for swimming.
I did own a Pulsar 50m quartz that fogged up after a swim ??
The screw down back needed a new gasket after 3 battery changes.
Problem solved. Swim with it often now,,, and no issues.
But, just a note that any quartz battery change requires careful gasket inspection to make sure the WR is maintained.
