This. If there was a big difference (e.g. higher resolution screen, larger storage, larger memory, faster processor etc.) you would thing fair enough at least you're getting something more for your money. But as it stands, you're paying 15x the price for some gold. Gold isn't that expensive.
For example. Rose Gold 38mm watch. The case weighs 54 grams which is approx. 1.905 ounces. Gold price is US$1203.70 per ounce. 1203.70*1.905 = $2294. So even assuming that the entire watch without the strap was solid gold (24k), it would only be worth less than $2300. Yet this watch costs US$10,000!!!!!!!!!
Lets look at the yellow gold 42mm version. Again excluding strap.
69g = 2.4339oz. Solid 24k gold is US$1203.70 /oz. Total price = $2930!!!! Yet this watch costs $12,000!!!!!
The profit margin must be massive on these! Now the price is definitely not in anything else because the Edition is identical in every way to the SS version, bar the case material.
Imagine the outcry from people here if the gold watch was better in terms of features/technology. People here would be livid. In some ways you could argue Apple Watch is the most egalitarian product Apple has ever released. No matter what you spend the technology inside and the software features are the same.
