I'll chime in with my fairly useless opinion and thoughts. Seiko is actually quite a marvel of a watch company and they actually make some pretty amazing watches. On one hand they make very accurate watches that they sell for practically pennies. That level of time keeping accuracy for that cheap is quite a feat in its own right. And they actually do make some very nice expensive watches.
The problem with Seiko is that it is handicapped by its own mass appeal success. You could have a $10,000 Seiko, but yet when the average person (who usually knows very little about watches) saw it side by side with a Rolex, they would "First" ask if that Rolex is real :tongue:, THEN they would immediately assume the Rolex was the more expensive watch. Way more expensive. In fact they would assume the Fossil or Citizen they have on their wrist is worth more than your Seiko. If that part of the equation doesn't bother you, then the Seiko is probably very technologically and mechanically sound. One thing to note, the more mass produced a watch is and the more distribution channels there are, the more over priced the list or MSRP pricing is. In other words, a Seiko might MSRP/List price a watch at $10,000 because it is a $1,500 watch, but that it leaves open doors to pay retails, have huge inventory sales, deals etc. But a more exclusive watch like an A Lange Sohne which retails at $10,000 would probably never see more than a 5% discount, if that. The List price is often the Sell price because they don’t make up the difference in volume.
It's like that very expensive Volkswagon Phaeton. It was a good car, expensive, but had a VW badge. Nobody could justify spending 90K on a VW, when no matter how good of a car it was, it would get lumped in with Jettas and Bugs. And if you notice, time has not been good to the resale value of that car.
