- Size: Approximately 36cm - Weight: Approximately 12g - Weight (parts): Refer to the photos of the back. This was attached to a late 19th-century Waltham pocket watch. After appraisal at "Kaitori Daikichi," the engraving was confirmed to be genuine. However, it is coated in black, and it feels light for pure gold. Except for the silver clasp, nothing was attracted to a magnet. If it is a composite material, they may disassemble it after purchase, so I am listing it as it is a waste. There may be a lot of gold, or there may be little. How about trying your luck? *I am not an expert, so I am hesitant to sell it as a gold product, and I am listing it as a golden antique. Please understand this. - Notes The entire piece is black, and the gold color in the first photo appears to be the underlying color. One of the hooks on both ends has been replaced (silver). Although it is a product photo, it appears brighter than it looks to the naked eye due to the lighting (it is much blacker). As it is a chain likely over 130 years old, there may be unseen defects, but I am not knowledgeable enough to make a judgment or take responsibility. Please make your purchase based on the photos. If you have any questions, please leave a comment.
