You need to do a little proofreading and quality control before posting. I’ve owned an Omega Seamaster 300M for 24 years now, and still know the line well today. The helium escape valve is the crown on the upper left. Not the center right where you pointed it out. You also mentioned it being able to sustain depths of 1,000 meters. It is rating is 300 meters, and 1,000 feet. That’s only around ⅓ of the depth you mentioned. You also had a shot of a black faced Timex watch in this video at around 19 minutes.
It's sad that watches that look good cost over 1k+. amzwatch watches are REALLY well made, and it just shows how a brand name on a watch can make its price 10x higher. I understand that if you look under a microscope, you'll find the difference, but just how many of you really inspect a watch at that level when you see someone with a watch?
