This Gold coin Watch is a 1904 Authentic American $20, 900 fine gold coin cut in half and an intricately hand made skeleton (Swiss Made) watch is hidden inside and encased by 18k. gold. This watch was purchased by the original owner for $10,000 in the early 1980’s and hand made by Langenbacher Goldschmied of Luzern Switzerland, which is a custom jeweler. You would NEVER know there is a watch inside, until you gently depress (with your fingernail) a vertical button located at 3:00 which is discreetly hidden at the edge of the coin. We just had this movement meticulously cleaned by our watchmaker and it is keeping accurate time. These watches often sell between $6-$10,000 the re-sale market. Be very gentle with this piece and DO NOT drop it. This watch comes in its original signed wooden box from the jeweler. This is a bargain at this price!
