It was a hit product, once selling 1 million units as the first thin automatic watch made in Japan. It is said to be the first model to adopt crystal glass. Even after its release in 1965, it continues to be popular, with re-editions being released, and it is known for its performance and durability. It has a practical and sophisticated design with a day window at the 12 o'clock position, a date window at the 3 o'clock position, and a 7 mark applied at the 6 o'clock position. The back cover is a screw back. The windshield is crystal glass as the pet name suggests, and it is a watch full of the charm of Japanese antique. ● Overall, there is no damage that significantly detracts from the atmosphere of a watch of this era, and it has a tasteful texture typical of a 1966 model.
