I don't mind the look of gold if it's a thin case/bezel, where the appearance is dominated by the dial, and the gold is only framing it (sort of a 'wireframe glasses' concept). To me that pretty much means pure dress watch, probably ruling out an automatic since that adds thickness, so handwind only (or quartz if you want really thin, but eh....). The red gold Hentschel Hamburg Admiral (8mm thick) I posted earlier is a decent example of what I'm talking about. On the other hand, if the gold dominates the design (the Rolex fluted bezel particularly comes to mind), I'd be much less interested. Obviously this rules out having gold on the bracelet.
All that said, speaking of shade, I don't know if I'd ever go for a yellow gold hue, probably only something with a more red hue.
Brass/bronze is nice too, if you don't mind it not staying shiny and developing an aged look after a short while. As for gold plating, it sounds like most of it is quite durable these days (at least any quality stuff), though of course if abused you can go through it. I don't think I'd consider it for a daily beater, but I wouldn't be opposed to it on a dress watch I'd pull out once every week or two.
Not familiar with Darwil, so had to look it up. Seems like it's one of the (many) Swiss brands that didn't survive the flood of quartz watches, and yup, quite popular in eastern Europe.
You should post pictures.
