Watches are a passion of mine and I have, or have had, them all - Rolex, Omega, Breitling, Longines, Heuer, Seiko, Timex, CWC, Swatch, etc.
What I've learned is that:
1. A quartz movement will always keep better time than a manual/automatic
2. The difference between expensive watches and cheap watches is the quality of the movement. Sometimes it's also the quality of the case/bracelet.
3. No watch is indestructible; but some are worth repairing if damaged
4. Most divers watches with helium valves don't get any deeper than the bottom of the bath. In the words of a US Navy SEAL "It would be easier to find a practicing astronaut than a person who actually uses the helium release valve for its intended purpose."
5. Most watches with multiple dials are owned by people who have difficulty coping with just one
6. If you want a watch for the long term, or if you expect a watch to be an investment, buy the best you can afford as you can always sell it
7. Watches are a useful indicator for telling the time, but not for telling someone's social status or bank balance
8. Men often have multiple watches, women mostly have just the one - men will trade in a watch if they want to upgrade, women rarely do
