Audermars - really on the strength of the Royal Oak.
JLC - some classic models including Reverso and Master Calander. Their complications offer great bang for buck.
Cartier - they may have turned a bit soft as a brand but over the years they have delivered more cool designs than anyone else.
While hunting for the next book on my list, I found this, that I reckon I first read about 35 years ago. I'm enjoying it just as much as the first time round. Though it's very dated it's hilarious and very well written.
