I don't wear a watch, haven't done for years. As a consequence, I can usually guess within ten minutes of any given time, except when waking in the night - so, if light, I get up and if not, I try to go back to sleep. Magic
Now I love a good watch but this causes me a problem, I have a splendid Oris Full Steel which was my first horologic indulgence and I was cock a hoop when they decided to sponsor my favourite team, Williams. I wear a Rolex most frequently, though, as it keeps better time and allows me to see the time in two places at once without complex maths. http://www.formula1.com/news/headlines/2012/12/14149.html
Personally, I prefer the appearance of the Breitling Bentley series-especially the bezel. However, the model I own is the Navitimer.
My most recent watch purchase is very cheap ($20) but interesting technology. It is a so-called "atomic" watch: a quartz movement watch which reads the radio signal sent out by the Bureau of Standards Atomic clock and continually adjusts itself to maintain absolutely accurate time! I've had it for four months and am very impressed.
