Watch prices vary drastically based on the brand, internal components (movement), and materials.
On the low end, you can purchase an S Coifman swiss made dress watch with an off-the-shelf swiss automatic mechanical movement (Sellita SW200), sapphire crystal, and genuine leather brand for around $150.
Moving up to a more well known brand, Oris, they make this Depth Gauge dive watch with a sapphire crystal, ceramic bezel, and a slightly modified version of the same Sellita SW200 automatic movement and a hydromechanical depth gauge incorporated into the crystal for $3500.
Moving beyond that you can get a sapphire crystal swiss dive watch with a ceramic bezel, and an in-house designed (less common) automatic mechanical movement like the Omega Planet Ocean 45.5 for $6200.
Rolex goes higher but is still what I would consider mid-level luxury.
At the ultra high end of swiss watches you will find examples that range upwards of half a million dollars or more!

A lot of Chinese replica watches are made of 316L steel and have real sapphire crystals. They make a mockery of the high end watch makers.
Very true. While not technically a "replica" here is a chinese homage to the Rolex Sea Dweller Deep Sea by a company called Parnis. It includes a sapphire crystal, chinese mechanical automatic movement, ceramic bezel, along with solid 316L surgical grade stainless steel construction for under $200.

The difference between the Apple Watch and a traditional mechanical watch is that the Apple Watch circuitry will become obsolete in 2-3 years. The battery can only be recharged for a finite number of cycles. The software apps that it runs now will eventually evolve to require more powerful hardware.
On the other hand fine mechanical watches can and are often passed from generation to generation as family heirlooms. Sure they do require periodic maintenance but if properly lubricated and cleaned can last indefinitely.
I believe it was Leo Laporte from the MacBreak Weekly podcast who had pondered purchasing an Apple watch and keeping it unopened inside the package to see if it may be a collectors item in the future. But he realized that 20-30 years from now there probably won't be any way to even activate the watch with a phone anymore.
