Well, here's my warning then to anyone reading this blog: these time pieces have a serious design flaw and Jacob Jensen got to be asked whether he knows and has factored this design flaw into his time pieces as a continuing source of income. The rubber arm wrist lasts just a bit more than a year. So, basically with the close to non-destructable titanium casing and the virtually unscratchable glass you bought a watch that could last for a very long time. How convenient then that Jacob Jensen forces his customers to purchase an expensive new wristband every single year (that's the half-life of these wristband in my experience).
I wrote to Jacob Jensen to complain about this, but duly got embroiled in fights over receipts and warranties. This, of course is missing the point. Say you got a 1 year warranty, that would give you at best one wristband free of charge (or none, if it lasted slightly more than a year). The wristband are designed in such a way that no regular wristband from your local watch dealer would work, it got to be the branded Jacob Jensen wristband.
Clever, hu? Your option is to either throw the thing out after slightly more than a year, or to become a permanent customer for Jacob Jensen's expensive wristband replacements.
For better or worse, I've thrown the watch out, and am getting even by trying to hurt his business just this little bit - by means of this blog posting. Don't buy Jacob Jensen products, there's probably a nasty catch!
