I have an IW3290 in my collection (!)
Its a pure Diver and it gets a lot of wristtime.
However the original strap is too small for a normal wrist (..)
it nearly covers the two rubber bands around the strap. If you replace the strap with another strap (the one of the IW3768 chrono) you'll find it much more comfortable.

Above the Perfect DIVING strap

When diving with the watch bear in mind that even that strap is too short to go over a divingsuit (!)
That's why I purchased an extra strap IWE01593 XL (issued with the deep three or the IW379402) this one is ideal for diving.
so the watch = perfect
strap = not for active divers (but ther are alternatives!)
good luck and do buy that AT(!)
