Question: are seiko watches good investments?
Answer: It will be better buying it used and in a good condition. However it will probably not retain its value very well. So in short, don't buy Seiko to invest. In spite of that, Grand Seiko can compare any time with luxury Swiss and German watch brands such as Rolex, A Lange & Sohne, Omega, Panerai, Zenith, IWC and Cartier.
