I'm about to do something against my better judgment, which is to say I'm going to take a stab at guessing Apple Watch pricing without having any appropriate knowledge with which to make such a guess. But guessing is fun and it will be interesting to see how wrong I am when actual pricing is announced.
That out of the way, let's start with what we (mostly) know, which is that the base Apple Watch Sport will be $349. Next, I have to imagine that there will be a premium for the bigger 42mm size. How much of a premium? $100 seems too much - that's the difference between the 6 Plus and 6.
At the same time, $50 doesn't seem quite enough. But Apple doesn't seem to mind throwing an extra $30 onto popular numbers like $50 and $100. Want LTE with your iPad? That's an extra $130. So $80 seems like a respectable Apple-like premium for an extra 4mm, landing the base price at $429 for the larger Sport model.
The pricing for the stainless steel variant is a little harder to gauge. Smarter people than me suggest it will be around $1,000 but I just can't see that happening. While Apple has proven that they don't need to compete on price, they notably lowered the initial iPhone pricing by $200 shorty after launch after encountering price resistance to what was then a relatively new product category.
So I think Apple will be more cautious in their pricing of the stainless steel watch. A $100 jump from the Sport model probably isn't enough of a margin to cover the more expensive casing and sapphire glass, but anything over a base price $500 seems like a tough sell so I'm going to go with a starting price of $499. Add $80 for the 42mm for $579.
I also imagine some bands might be more expensive than others, adding another premium if, say, you want the stainless steel band.
I'm not going to take a stab at guessing the price for the gold Edition model. The same smart person from above has suggested $5,000 though. He tends to be right about these kinds of things.
Check back in April when actual pricing is announced and I try to back down from just how wrong I got it.
