They're two same same but different watches, so it's not really like-for-like when one replaces the other in your collection. But if you have the Rolex itch, and this is the way to 'back door' yourself into having one, why not? So the real question is, how bad is the itch?
Since the Omega and Tudor went off for sale a week or so back, my main go to watch at this moment in time is quartz, and I have zero issue with it. When the Tuna was designed, quartz was the absolute no-brainer for the task at hand. Plus, it's far from a run of the mill quartz, being a high-torque quartz. Anyone who writes these off "for being a quartz" may as well put a sticky note on their forehead that says, "I don't really know anything about watches..." It's an absolute ripper of a watch on so many levels; design, movement, case.
The flipside to that coin is, as I mentioned earlier, people getting quite hyperbolic due to the 'bang for the buck' factor of AliExpress watches, and sometimes going on to say quite silly things. My example of someone saying their San Martin was as good as their mate's Aqua Terra is a comment I have truly seen made, with no tongue in cheek to be seen.
Indeed, and you are quite right to flag that it's all about where one is in their journey. For example, I own a Seiko Tuna (the last model they plastered MARINEMASTER on, before switching over to the Prospex X on the dial), so there could well be a half-decent homage on AliExpress... but I'm not going to be buying it. Makes no sense at all. I'm not the target for that. Meanwhile, someone was on here recently asking if they should buy an AliExpress homage of the Seiko Turtle, or just buy the Turtle 'for real'. Once I ascertained that they had other watches, and had been collecting for awhile, my strong advice was to just buy 'the real thing'. That, to me, was a no-brainer. But if that person was more like, "I've never had an automatic watch before, and I don't know what I don't know about watches..." I might well have pushed them towards the homage. So they have their place, absolutely.
