This is a rare black snailed dial pink letter model with a screw back waterproof case that is more than 38mm and a rare black snailed dial with pink letters. It is a hidden gem with excellent design and quality even though it is unknown, as it is equipped with the famous Valjoux 22 that many brands such as Rolex had adopted. There are some aging changes, but considering the famous Valjoux 22 equipped, 38mm screw back waterproof case, and black snail dial, it is an individual with a sense of value.
