I quite like that model, too, for it has quite a bit on vintage-y appeal to me (the dial and sub-seconds, great design). But if your mother is looking for something "fancy", with ceramic watches being all the rage among refined women these days, including my own mother, etc., might I recommend you look into Rado? I just looked it up on Amazon for you and see they've a Rado Women's R25474102 Cerix Watch for $835, but if you search, you might be able to find this (or other, discontinued models) closer to your price range.
If not, or you otherwise don't like it, not to worry; other brands that come to mind at or near your price range include,
Baume & Mercier. (Women's 8768 Iliea Swiss Watch, $576 Amazon; the Women's 8339 Hampton City Watch, $586 Amazon, looks quite elegant yet sporty or, if you would like something a bit more sporty, then Women's 8742 Hampton Square Pink Watch, $590 Amazon). B&M makes nice watches, some very nice designs, with the Hampton City in particular being stylish yet at the same time professional looking. Looks to be true to me of the women's line also.
If you'd like something a bit more fancy, why not have a look at what Gucci has to offer, such as their Women's YA121515 Marina Chain Watch
,$550 Amazon. Seems to be quite popular with women, the jewelry-watch style. Another you might check out is the Movado Women's line, such as their Rondiro, Stato or Esperanza line which, if you search you can find online from $500-600, respectively (very popular brand, very classic, and they're out there, available in the said price range, just have to search 
Another brand that seems quite popular among women these days is Bulova, which has a rather extensive line of quartz women's watches from which you can choose, all well within your stated price range.
As to quartz, I agree that that is probably best if your mother isn't into wearing watches; with quartz, it's all about "set it and forget it", with basically no maintenance required (i.e., apart from the occasional battery change, and thus all about convenience, etc. as has been noted). Though the eco-drive option might work out well, too. Just some more ideas for you, Bronte, and welcome to WUS! Hope that this helps.
Cheers.
