Does the second strap for this model allow for water activities as well as any rubberized type of strap or does it perform more as a leather strap rather than rubber? Thanks. Also those that may own this watch do you feel that it is good everyday watch including taking showers with it on. I am considering trading a yellow gold aquanaut and a 3800A ss nautilus straight up for this model and would appreciate any thoughts on the trade as well. Thanks.
