I just purchased a watch. It is a model wt1110-ba0550 link. It feels solid and came with the tag box and warranty card (not filled out). The card not being filled out makes me a little nervous, so I opened up the back to see the movement. It is not marked with much that I can tell, but is stamped "there jewels". Other than sending it in for an appraisal, is there another easy to verify its authenticity?
