Fair enough. How much did Rolex cost when you first buy it? Omega?
I have no doubt that your grand kids will appreciate a Rolex that is 30 years old! Or will they? Look at the current generation of kids and how they do NOT like to wear watches! But in that 30 years to keep your Rolex running like a gem, how much investment did you put into it? Is it worth it?
So, lets say a Rolex costs $8000 to buy. 30 years. Service every 5 years. Cost of each service $800 or more...the latter services cost over $1000 due to replacement of vital components! After 30 years, your Rolex at a MINIMUM has cost you: $8000 + $4800 = $12,800 (or more).
Apple Watch average price...lets say $500. 30 years. Replace it every 5 years. Total cost = $3000.
If you're lucky, then your Rolex has gone up in value in those 30 years...but it has to be a special limited production Rolex (like Daytona)...most Rolex does in fact LOSE VALUE with time!
