If you can include paths, it is sufficient

I looked for a clock that is waterproof, can count laps / stop and at a good price / performance ratio.
In addition to Sigma Garmin also offers a Schwimmuhr which counts even the paths independently and recognizes the swimming style. But after I am planning the training in advance, ie distances and swimming style fixing, my, this is an additional cost of ~ 100 not worth (according to the resonances it seems not always to be working).

After 2 months of use (2-3 times / week) I'm satisfied. No failures and stopping runs without problems. The criticized imprecision in the printing point I can not confirm. In addition, each entry is completed with a control tone which is still perceptible even underwater with headphones and playing music!
