You can watch the full video and my other Rolex Submariner test videos on my channel. Left my watch in the super hot sand for hours to test in Florida. I am sure Rolex hates my tests of their Submariner, but they got nothing to worry about. This watch is still ticking and purring like day one! It was scorching to hold after I dug it out of the sand. No watch was hurt in the process, LOL.
