The 5646-7030 (dial code 7040T) is a rare reference in the 56 Grand Seiko series which ran from 1970-1974. It has a unique sand textured almost snow like texture to the dial and is a fan favorite amongst vintage GS collectors and is highly collectible. The dial has most certainly  inspired many of the textured dial that exists in today’s modern GS lineup. 


This is an all original vintage Grand Seiko 5646-7030. Overall, this piece is in great condition. The case has been polished in the past but retains sharp edges with the bevelled and and brushed finishing of the lugs still prominent. The original textured white dial is in fantastic  condition with no visible blemishes or discoloration. The crystal has some tiny scratches but is in good condition. The handset and crown are all original and in excellent condition as is with the daydate wheel which has a lovely kanji day wheel. The last servicing date is unknown but this watch seems to have been take good care of based on the servicce history recorded on the case back. The movement has been checked by our watchmaker and simple adjustments have been made. It is currently running at -7.4 seconds / day. The gold medallion is mising from the caseback and this is reflected in the asking price of the watch.
