Introduced in 1963, there are three different iterations of the 57GS series over the course of its lifetime being based on three different movements. The first example of the 57GS series was a model numbered 43999, based on the 18,000 bph 430 movement. This was followed by the 5722-9990 – typically utilising the 5722A movement, and finally the 5722-9991, using a 5722B movement which ran at 19,800 bph.

 

Overall, this GS 43999 is in great vintage condition. The case retains its thick lugs and although there are scratches and bumps throughout, one can clearly appreciate the original sharp bevelling. The original silver dial is clean with some minor spotting throughout but overall very clean for its age. The dial is the coveted and rare SD (special dial) dial variant as can be seen by the sun logo above the six o’clock index. The SD logo signifies that the index are made of white gold. The handset and crown are all original and are both in great condition. The gold lion medallion on the caseback is original and is in crisp shape with just a tiny crack on the lower right. The watch comes with a period correct inner and outer Seiko chronometer box which was actually used throughout the 57 Grand Seiko series. The 57GS were sold around the same period as the Liner chronometer. Hence, the reason the boxes were marked as "Seiko Chronometer" and was most likely used for both models. This is also the reason why the box does not have the Grand Seiko logo like the Grand Seiko First boxes. The inner and outer box alone is extremely rare.

 

The movement has just been serviced by our watch maker in May 2021 and is running well at -1.9 seconds / day. It will come with a 3 month movement warantee.
