I see lots of comments about Rolexes.
Prior to quartz crystal watches, Loran and GPS, an accurate watch was a necessity for navigation. That was what really made a Rolex a ROLEX. They were the choice of mariners due to their accuracy and reliability. The world has moved on from there, and now they are pieces of jewelry. I am not a believer in expensive cables, but admit that I have not A-B'd them. My extra nickels go into music and if/when there are enough, perhaps equipment. Of course every time I move up one piece of equipment, I know that I need to have saved enough for the next weak link in my system until it comes into balance again.
