Grand Seiko 5646-7010

Grand Seiko 5646-7010 Day-Date

I wrote about 56GS in September 2010 HERE.

"The 56GS marked the era of mass production with the aid of robotic automated process. There are also concept of standardization of design and movement. Therefore the 56GS shared identical movement with King Seiko, and Lordmatics. However the GS movement had a better finish and was tweaked to GS standard accuracy."

This is a 1972's production of Grand Seiko 5646. This watch has a white dial with slim silver hour markers and hands. It is 36mm in diameter excluding its crown. This watch is with quick set day-date and the day date functions are at 3 o'clock position. One can choose between English and Kanji for the display of day. The crown is beautifully signed with GS. 

This watch still has the Grand Seiko original bracelet on it. The bracelet is very fine and well built. It grips on the wrist very gently and serves its purpose well. 

The only disappointment is the original embossing GS lettering had fallen off. 

The gold medallion at the case back is still intact with some minor defect. This watch used Caliber 5646A, which is a 28,800 bph automatic movement with 25 jewels. It can be manual winding and has hacking function.

Does not matter, whether it is contemporary or vintage; automated production or human finishing; Grand Seiko has stood for the same simple yet exacting ideal, perfect precision, legibility and beauty. A Grand Seiko watch is a watch for a lifetime and longer......
