I bought a new sub a year and a half ago from a local AD. I told him I preferred to buy local but was considering buying out of state and having it shipped to save the sales tax. They offered to meet me halfway by giving me a single digit discount, but it involved a lot of "let me talk to my manager."
Apparently there was a precedent for such a test based on a similar one conducted on the oyster case in a 1960 deep dive.
Nice video of Cameron discussing the experimental watch:
If we want to be precise: Cameron wore the regular DSSD inside the submersible. The Deepsea Challenge was strapped to the outside of it.
All of these spoilered items are my consignments. Ask Spoo for measurements, but I'm happy to answer any other questions by PM. I've also included two "fit" pics I managed to find of the Isaia sport-coat. [[SPOILER]]
