I prefer the bracelet to that particular NATO. I think a NATO might be a good option, but I would pick one less colorful than that. I see you picked out colors from the dial, but the dial is mostly black with a tiny bit of color while that strap is pretty colorful. 

This weekend I have no watch on. My left hand has some nerve (and possibly circulation) problems, so now and then I have to take the watch off and give it a few days to recover from the pain.

Before that I was wearing a titanium Citizen Eco Drive with sapphire crystal, and a three hand face with date. It's my daily beater for when I don't feel like wearing a nicer looking watch. (Woe is me, my "daily beater" is an attractive titanium watch.) 

Actually sunday morning a friend wanted me to show him a few automatic watches I have, and he liked those, but he was much more intrigued by the Citizen and may buy one of those instead. He usually wears an Apple Watch but is looking to have something more attractive to wear for nicer occasions or for when he wants to take the Apple watch off to be away from work for a while.

I neither love them nor hate them.

Rolex, I'm told, makes a good quality watch, and a few of their designs are very attractive. My problem with them is that nothing ever changes with them - every year everyone gets all excited because they came out with a new color (ooh! grandpa's watch is now available in blue!) or they took a tool watch that was designed to be used for diving and put diamonds on it. (What could be more useless than diamonds at the bottom of the ocean?) 

I'm sure it's a very good watch, but I can't see spending $150,000 on a watch that looks like every other watch they've ever made and is blingy in ways that are useless to the functional item it is designed to be.

You should get one if you want and not if you don't. In today's world, when there's an Internet connected computer or a phone everywhere in sight, and you can usually find out what time it is by saying "Alexa, what time is it?", a watch is an affectation in the first place - given that it's already something you don't have to have, anything at all you spend on it is unnecessary, so you can spend as little - or as much - on a watch as you feel like. 

I happen to like fountain pens as well as watches. a $20 pen is nicer than a $2 pen. A $50 pen is nicer than a $20 pen. There comes diminishing returns, however - a $120 pen is nicer than a $50 pen, but a $200 pen isn't especially nicer than a $120 pen. Yeah, they make $600,000 pens. They're very pretty. You can't get one with that kind of decoration for $100,000. However, the $600,000 pen doesn't write notably better than the $200 pen. 

No luxury watch is going to keep more accurate time than a $20 Casio. The reason to spend more than $20 isn't because you need it, but because you want it.

Life isn't all about being utilitarian, or we'd have nothing to live for, we'd have no soul.
