Vintage Women’s Royal Star 17 Jewels Wristwatch (Not Working)

Preowned, Vintage - guessing 70s - 80s (not confirmed by a professional). Wind up mechanical watch, no batteries. Condition: Not Working. Watch has not been cleaned or serviced. Attempt repair or use for parts. Back of watch is stamped “Stainless Steel Back”, “Base Metal”. Band is stamped “105”, “S.Springs”, “S.S.Back”. The band is stretchy and feels really comfortable on my wrist which measures approximately 5.75” around. There are no gaps in the band when worn on a wrist that size. Love the interior cuts around the edge of the crystal on this, really pretty even with normal light scratches from wear and the need for a cleaning. Please see all pictures and video to aid in description and for signs of age and wear. All taken with overhead light on, no filters used.
