As someone who took up an interest in watch repair later in life, I now understand why the better watches are cased in gold. It doesn't corrode.(makes working on easy) It warms(thermal heat transfer) up to the skin quicker than, I believe any metal. Easy to polish. The negative, besides wasting money(unless the consumer feels the gold iwatch is an heirloom), is you can't wear it everywhere.(certain people look at my old gold sea master like they would chop off my wrist in certain areas.)

That said, when I look at the current gold Iwatch--I just think about the melt value. I can't think of any gold watch manufacturer who didn't produce a watch thinking the consumer could theoretically keep that watch for life, with the proper care. Sorry, about rambling on--I have just thought about this watch too much. I don't have an exciting life.
