Gazzla 25 Posted December 30, 2015 Hey Gang Recently added to the collection a rather splendid vintage Grand Seiko. This Grand Seiko was manufactured in 1968. It has a glorious calibre 6146-8000, hi beat, 36,000 BPH movement, housed in a gold capped, stainless steel case. It's a truly gorgeous time piece. Some pics with a more detailed analysis as we go: Case: 36mm stainless steel with gold capping. Gold capping is similar to plating but much thicker. Typical gold plating is around 30 microns or so, whereas gold capping is typically 200 microns or 0.2 mm. Gold capping is achieved by heating sheets of gold onto the top and sides of the case, effectively 'capping' the case in gold. The underside of the case is lightly brushed SS. 18mm lug width. It's not in bad nick for a near 50 year old piece. You can see from the pic below the thickness of the capping especially around the lugs: Caseback: The caseback is fairly standard Seiko fare with a GS gold disc logo in the centre. It tells us that this is indeed a gold cap model and that movement is a calibre 6146-8000. The serial number, 8N1427, tells us that it was manufactured in Japan in November 1968. We can deduce this by deciphering Seiko's serial numbering system. The first digit, in this case the '8', refers to the year in the particular decade it was made. But how do we know it's 68? Why not 58 or 78? Now we have to do a bit of detective work. We know that Seiko only made this movement calibre between 1967 and 1974, so the '8' can only be 1968. The 'N' that follows means November. Seiko uses the numbers 1-9 for Jan to Sept then 'O' for October, 'N' for November and 'D' for December. The following 4 digits, 1427, denote the particular piece in that year. Any Seiko can be dated in this fashion. Movement: This is the interesting bit and the main reason for acquiring this beautiful piece. The movement, as previously mentioned is a calibre 6146-8000 made between 1967 and 1974. It runs at 36,000 beats per hour and sweeps round with refined elegance. It truly is mesmerising. The crown operation is solid with quick set date, however the day needs to be adjusted by moving the hands forward. Seconds hack and it manually winds, too! Usual GS crown marking. It runs like a dream and my preliminary observations are that it gains 4 secs a day. Dial: The dial is silver and has taken on some patina and a little minor flaking over the years. It's accentuated by gold hands and markers and day/date window borders. Strap: It came on a generic vintage croc strap that I've since donated to Frazzle for his vintage JLC project. I've temporarily put it on a gorgeous RIO strap - the one in the pics - while I wait for a proper Seiko strap to arrive: Now all I need to do is give it some Cape Cod loving and it'll be ready for a photoshoot! I'll leave you with this. The Grand Seiko calibre 6146-8000 accompanied by another favourite masterpiece: Beethoven's Fur Elise: That sound you can hear at 14 secs is me cracking open a beer!

I know it is on the smaller side for you but I am going to guess we still won't be seeing this one in m2m anytime soon; a keeper to just have in the collection.

I thought the dating of the serial no. would be of help to some that have older Seikos. I seem to be going away from big divers etc, to smaller stuff. Fuck knows why . . .

MoveAlong 23 Posted December 30, 2015 Nicely done, mate! The SARB must have helped pave the way for accepting a smaller size? I'm not a gold man, but I would be all over this GS! Again... wow!!!! Share this post Link to post Share on other sites
