The weight is about 140 g i believe. It is very comfortable with the original rubber strap. I got a tan python strap, but have put the original one with a blue logo... Great quality rubber, by the way. I ordered blue sting ray band matching the watch highlights - will see how works together...by the way the material feels and looks (and keep temp) much more like a stone, than plastic. In fact there is nothing plasticish about it - it is like a stone or ceramic to the touch, and you can't really scratch it, so I think these have better chance making it over next 50 years than SS cases... the material is very impressive and high grade...
