The Vintage Seiko Men's Quartz Perpetual Calendar Watch features a classic round case with a polished silver finish and gold trim. The fold-over push-button deployant closure and bracelet band in gold and silver stainless steel add to the watch's vintage appeal. With a 37mm case size and a 20mm lug width, this left-handed watch is a timeless piece from the renowned Seiko brand. The blue dial with stick indexes, quartz movement, and perpetual calendar feature make it a reliable and stylish accessory for any man's collection.  Does have a few light scratches on the crystal, not brand new.  Brand new high end battery has been installed.  Dial is either dark blue or black, I cannot tell the difference.  I really don't understand how the perpetual calendar function works.  Nice looking watch that will fit a 7" wrist, no extra links.
