SubaruWater Resistance numbers doesn't necessarily mean what they say (100m does not mean you can swim to 100m deep with no issues). You might already know this but I thought I should clarify regardless.
That all being said, most would agree that 100m is fine to swim with.
If you want to be sure, 200m and above is what you're looking for.
JimHarrisThanks Jim. Of course I know that, but practically we need 1-6 m. max. for swim and play on the water. Anyway it seems to me that this Seiko is a super deal.
