This Orient has a 469 21 jewel movement, which is a factory modified 7005 ebauche acquired from Seiko. It is still considered an in-house movement by Orient because of heavy modifications it made on it, and allowed by Seiko .Orient is one of the very few in-house watchmakers in the world. Although now owned by Seiko , Orient still operates independently. This is a collectors model, not rare, just quite unique, yet very similar to its competition. It has kept time w/ the wall clock for @6 hours Changed Mind,Doesnt fit or Didnt Like as the reasons for return will approve the return automatically and allow a pre-paid label to be printed(Free Returns) and entire payment returned.. Choosing Defective or Not as Described will require a detailed explanation as a few of those entail stiff monetary penalties to the seller by EBay and is a longer drawn- out process. International buyers have to return at their own expense w/ tracking, and will refund entire payment when received back. Thanks for understanding.
