Seiko Goldfeather SEIKO Goldfeather TWENTY-FIVE 25 JEWELS SEIKOSHA No.107650 Note: This is only the movement (mechanical part). Named "Goldfeather" to mean "a watch as light and thin as a feather." The product uses 18K solid gold for the case material, and is an ultra-thin watch with a case thickness of only 7mm. The movement itself is only 2.9mm thick, with 25 jewels. At the time, thinness was a sign of luxury and technology, and this masterpiece was developed with the aim of achieving the world's thinnest watch, representing the culmination of Japanese technology at the time.
