Grand Seiko 56GS 5646-7010 Navy Dial





When starting your journey into collecting vintage Grand Seiko watches, the 56GS series stands out as an excellent choice.


Introduced in 1970, the 56GS series offers a diverse range of 35 models. It was the first to feature an ultra-thin automatic caliber, measuring just 4.5mm. Adhering to the Grammar of Design principles, the -7010 and -7011 cases boast sharp edges and a brushed finish on the surfaces between the lugs, making them some of the most common and sought-after vintage Grand Seiko models on the market.


Among these, the 5646-7010 is particularly popular. Embracing the iconic Tanaka Taro "Grammar of Design" also seen in the 45GS and 44GS, this model features a day/date complication with an English/Japanese day wheel and is powered by the precise Hi-Beat movement Cal. 5646A. While the white dial variant is stunning, the blue dial versions are exceptional.


The navy dial variant is especially noteworthy for its rarity and striking appearance. The impressive case proportions and slender hands, coupled with silver indexes, make the navy dial variant versatile and eye-catching.


This example we're offering today has all the signature elements of a vintage 56GS: Navy blue dial, non-lume dial? Check. immaculate G.O.D case? Check. A beautiful set? Check!


Whether you have been searching for this rare blue variant or are looking for a standout piece to start your vintage Grand Seiko collection, this watch is the perfect choice.
