I like the movement and the finishing on the dial!

I'm not sure about your understanding of how water affects the weight of an object, your arm does not become "significantly heavier", it is in fact somewhat supported by the water's buoyancy. You should research Archimedes' Principle of Buoyancy, here's a place to start: https://www.britannica.com/science/Archimedes-principle

Your argument about your observation, where you wear a brick on your wrist, does not support your point either, it is just rephrasing the thing you said before.

I will agree, though, that your Orient is too heavy if you're having to take it off after a few hours due to fatigue.

Romain Gauthier makes highly specialized, avant garde watches. Usually their pieces cost an arm and a leg for people like you and I, assuming that we all here live roughly the same financial standing, but RG makes only like 60 watches a year.

Romain Gauthier has its bracelet inspired by VC, The bezel is the same design as a Victorinox Inox, obviously extremely well executed, Movement is killer tho.

Did ya ever notice that water is wet? I know!… surprised me too!

The orient mako that I own, weighs 6.4oz, it's about 181 grams. Even mako gives me so much trouble with the weight that I have to take it off after 4-6 hours of wearing it… and that's not even underwater but on land. Now the deepsea weighs a whooping 320 grams, it's even 139 grams more than the mako.

Just imagine all that weight on your arm while being underwater, the left arm becomes significantly heavier than the right one and puts more stress on the right one, resulting in the diver exerting that extra effort to maneuver.

The other argument to support my observation is that if you literally wear a brick on your arm weighing in multiples of kgs, then you would feel significantly more difficult to dive with it, what do you say man?
