On some straps ther is the PUR marking.

PUR is a common kind of plastic.

http://en.wikipedia.org/wiki/Polyurethane

So its no rubber.

 

I would say it's a flexible urethane. If the Giez strap was any softer, I'd say it was rubber.

 

I've always heard that the Giez bands are rubber. Certainly a different feel than all the other Casios I have.

 

See, that's what I thought, but someone posted up in one of the Giez threads saying it was urethane based on the information on Casio's site.

 

Ohhhhh, so it not the same stuff these are made from?

cuz, I heard this stuff is pretty darn durable! : )

 

these would feel good on my hand as well :-d

 

Are you talking about her contact lenses? :-d

 

uuummm, uuuh... yeah...thats what I meant;-)

 

According to Casio, the bezels are urethane.

Also according to Casio, the Giez bezels and straps are made of urethane, but a special molding process makes it feel like natural rubber.

 

Does this mean no matter what resin will still break down overtime?

"A polyurethane, commonly abbreviated PU, is any polymer consisting of a chain of organic units joined by urethane links.

 

Does this mean no matter what resin will still break down overtime?

Yes, 'resin rot' is well-documented on the forum.

 

just like microwave oven, its an alien technology captured by the men in black in the fifties.:-d

 

Re: The Scientific Answer

316L,

As a self-proclaimed expert and scientist, I am here to inform you unequivocally that "resin" is the strange black substance from another world that crashes to Earth in Spider-Man 3.

This scientific explanation is the key that finally unlocks the mystery to our G-Shock obsession.

ah that would indeed explain why we go crazy when Casio issues a new G-Shock.

 

How long does it take for resin to rot?

 

My favorite is the frogman band, which feels much stiffer and has a deeper texture than others. The giez does feel more soft and rubber-like. So many G-Shock bands are kind of shiny and plasticky, the thin ones like that feel cheap to me (like alot of models in wal mart). THere are thicker and stiffer versions of the plasticky kind though which I like. The worst are the thinnest plastic bands with a plastic buckle (hardly a step up from the $15 casio non G's).
