I got a titanium one, to match the handles on my Sebenza, and to save weight over stainless steel.
The above is 3/4 true, the reason why is not as given, but it is convenient. It is lighter and tough. The main drawback is price.
I actually got it because I was developing a nickel allergy to my stainless steel watch. When it got to the point I started bleeding, I said I am going to get a new watch, no matter what. If you look at plastic watches, most have a stainless back. I could not get a Seiko Titanium if it had gold trim, because it wraps around in the band and has nickel. I could have tried one that is hypoallergenic, which I think was marketed by Armitron???? called Durasteel as I believe, in other words NOT the whole line.
Now to the no matter what part. Costco did not have Seiko Titanium watches, Kinetic or otherwise, at the moment. JCPenney was having a sale, plus an extra 10 % off sale. I started looking at the Citizen Eco-Drive Models as they are Solar powered....but even on sale they were expensive. No titanium Seiko Kinetics in stock. Have you gotten the idea yet, that I do not want to get batteries changed? They must get paid some commission there. When the sales person finally got the idea that perhaps I was somewhat hesitant to make an instant commitment at those prices, she finally showed me a section that they had marked down 50 % because the box or instruction manual or similar was missing.
To get to the end of the story, there was a Bulova Marine Star, titanium, and solar powered for 50 % off. I need my reading glasses to see the date, but great watch. It is off about 1/4 second per month. It is water resistant to 100 meters, in other words enough for ordinary swimming, fording a stream, etc.
Despite wearing it all the time, it is still in good shape, a couple of years later, of course I have a sedentary job. Working in the yard or hiking is about as rough a life as this watch has.
