A unique and very characteristic Grand Seiko model. This is a real diver with a clearly tool character, but with the attention to detail and finish typical of Grand Seiko.
The envelope is distinguished by a more angular, decisive form than in the Spring Drive models from this line. The ears are a small work of art – multi-faceted, with numerous edges and transitions between brushed and polished surfaces. However, the whole thing retains the coherent, raw character of a tool watch.
The crown located at 4 o’clock increases wearing comfort and eliminates the problem of wrist pressure. With a diameter of 43.6 mm, a lug to lug length of 49 mm and a thickness of approximately 13 mm, the watch wears very well.
The heart of the model is the legendary Grand Seiko 9F quartz movement – one of the best in the world. It is known for its extraordinary precision, durability and quality of workmanship.
The offered copy comes from 2023 and is sold as a complete set – boxes and documents.
Very good condition – slight traces of use.
