Serial Number 16048335 was reported as inaccurate.

Note: Mine is pendant wind and set. I double checked the
serial number and it is accurate. Not an expert
but the amount of plates on movement is 4, not
sure if that is considered 3/4 plate. All other
info seems correct. Thanks for your wonderful site
