I have purchased a Vintage Movado Ladies wind up watch with 1.5 carats of excellent quality fairly large Diamonds with 14K watch case and 14K "rope with many strands" type band. May be "Art Deco" and it is, without question, the most beautiful watch, or even Jewelry I've seen. However it had mechanical problems. The movement is a Contina 17 jewel that is a long and very narrow rectangle. My first question is "Could this be the original movement, a Contina in a Movado watch?". My second question is "where can I have this movement repaired or replaced - if it is the original?". I have had a local shop remove the Contina movement and install a Vintage as new 17 Jewel Swiss Lucien Piccard movement. I view this as temporary while I get the original movement repaired/replaced. I have had appraisals that are approaching $10,000 for the watch. The gold weight and Diamonds alone are approx. $3,000 in melt value and salvage. Does the Lucien Piccard movement versus the Cortina, impact the value of this watch? After many, many hours of internet search I've seen absolutely nothing like this watch. A local Jeweler suggested that it may be a "one off" Movado as he can find nothing like it either. Any help appreciated. Best regards and have a great day.
