I still have and wear both my Seiko titanium samurai and my Citizen Aqualand Duplex. The Citizen is quartz, and I put a battery in it every 3 years or so....and the Seiko keeps great time. Both my watches get worn 24/7...whichever one I'm wearing at the time. The only time I ever take one off is to swap them out. After hours and hours in salt water, chlorinated water, etc, the titanium cases look great.
I did buy a cheap Casio to wear while riding my dirtbike, because I was afraid of damaging my other two, but I never wear the Casio.
