Seiko watches are highly coveted but even more coveted are the Seiko Limited Edition Watches. These are watches that are produced in limited numbers. They are usually feature packed and each watch comes with a unique number engraved on the back. Since these limited edition watches are few, the demand is usually high and they are out of stock a short while after launch. Those who buy them can then sell Seiko Watch for a higher price than they bought them. They are sought after by collectors and are not only a time piece but an investment as well.
