Also when talking about the value of a watch, what about the features that you will never need. People pay $10,000 for a genuine Deep Sea Sea Dweller even though they have no intention of ever doing any saturation diving. How many helium release valves have ever released helium? Talk to the 600 or so saturation divers on the planet, how many of them can afford and wear a DSSD, and if they got one free, how many would actually wear it to work? They're all wearing Casio G-Shocks.
