And, luckily, if your biodegradable plastic watch stops working in a week or two you can bury it in one of those pots to feed the plants.

Hey, a bit of Casio variety! I have seen enough pics of F91W and AE1200 to last me a lifetime

Is that a Pagani? There is a whole bunch of logos that are similar to this and I'm never 100% sure...

I have been told that Erebus watches are also made in the SanMartin factory. One of JOMW recent videos has footage from the factory.

Well, in Gary's video one could see that the SanMartin had tighter tolerances than the Rolex, and in several of those other categories it also a close call if not favourable to the SanMartin. Case in point, and relating to another of your issues: Rolex's patented lume showed up as a damp squid. SanMartin's lume was whiter than the supposedly super-while Rolex lume, and they lasted about the same.

Generally, Rolex is renowned for taking credit of innovations that were not theirs to begin with. As a horological innovator they are a bit meh for a 100+ year old watch company. Their biggest contribution is really to the markeing of watches.

Regarding how well the respective employees are paid, that is pure speculation. I take it that pretty much nobody knows for sure. Of course, in absolute terms you have to pay Swiss employees more, because Switzerland is a very expensive place to live, even by West-European standards. A universal truth in paying wages is that if you pay peanuts you get monkeys, and I doubt SanMartin could produce the quality they do if... Anyway, this is pure speculation and you are kidding yourself with your own prejudice if you make that a criterion.

Rarely, but still sometimes. I sometimes ponder about the watch for the next day, and if it is a self-winder that is a good way to build up the power reserve. Or, I'm wearing a handwinder and I noticed it stopped because it was insufficuently wound. That I take as a sign to switch.

Not a fan of two-tone, but in itself that is not enough to reject a watch. I recall a two-tone Chronomaster of another watchcruncher which was drop dead gorgeous. But these Islanders get a No from me, probably mostly from the fluted bezel. I was first thinking that the issue was two-tone in combination with a dark dial, but the Rado posted earlier looks fine to me despite that combo.
