So, the band is really worth $2,250 of the WATCH you paid $17,000.
OK, so most likely the band won't fit on the WATCH 3rd Gen; therefore, you can only sell it to a gold dealer for 1/2 price ($1,125).
The WATCH 1st gen in 3 years, itself, $170 (who would pay more for an obsolete thing??).
You take a $15,700 haircut in 3 years + $1,360 in original sales tax, and THERE IT IS: a $17,060 LOSS.
Therefore, $170 is the salvage cost in 3 years.
Dude, you ain't got no $18,360 Rolex.
In 2018, all you got is a 3 year-old, 1st Gen Apple WATCH, one of 4 million, (with q battery going lame and a screen full of scratches).
