18k Tiffany & Co 5 (Five) Minute Repeater believed made by Patek Philippe & Co

Showing the activation of the repeat mechanism using the slide in the band. Dial view and movement view. The movement jeweled to the hammers. Open face pocket watch repeating on two gongs. The repeater will sound the hours elapsed and then each 5 minute period that has elapsed. Note the hands are a little out of sequence on this watch. This watch made early in the 1900s and was very expensive to purchase back then. These are considered complicated watches and require a lot of expertise to manufacture.
