Good post!
What about the 7c46 quartz in the marinemaster Tuna’s? How does that stack up to the Grand Seiko quartz movements?
High-End Seiko Movements
INTRODUCTION Watch movements are tiny, wonderful, mechanical marvels. In essence, they cause the hands of a watch to reliably revolve at a precise speed, for at least one and a half days per winding, for many years. To achieve this, movements are made up ...
Thank you so much for such an informative article!
All my GS 9S movements performs perfectly however my Credor 6870 failed only after 2 months of purchase. Apparently there are only a few old masters who handles the assembly of 68 ultra thin movements in the workshop, and they, with all respects, made mis...
I’m sorry to hear that
I took my 6899 out while writing the article. I’m always amazed at how little material there is in this movement. Hopefully one of the old guys will get it working properly for you. Cazalea ...

Here is some info on the 7C vs 9F movements
No doubt the 7C series is an excellent movement for diving. However, as the first digit of the movement number goes up, the movement specs and finishing improve. Thus a 9F is roughly two steps higher than a 7C. I can't speak for how Seiko spaces or define...
WOW!
That’s probably the best answer I have ever seen! How do you know so much about these movements? Your GS looks amazing. I had their recent high beat with the 9S85 but wound up trading it and now miss it!
How do I know about the movements?
Just curious, plus willing to go overboard on research. owned a variety of Seiko watches (let's say a round number of 100) in the past 20 years had about 20 Grand Seikos, mechanical, quartz, and some early Spring Drives from 1999-onwards visited the two m...
very good read and thanks for sharing this article however some important points to underline
As much as Grand Seiko is making nice quartz operated high end watches (springdive) , it isn't really taken in consideration by collectors. Their mechanical watches are very nicely made and are an interesting alternative to the swiss made watches
Those are important opinions rather than objective points
If you say "serious, high-end, long-time collectors of expensive watches" I will agree with you. They may not have even seen a Grand Seiko. But I know many watch collectors who have added a quartz or Spring Drive Grand Seiko or two to their inventory, aft...
I finally....
got around to reading your article after I had left it open in my browser for the past twenty days. Unsurprisingly brilliant commentary which left me with a renewed appreciation and even greater insight into these watches. Much appreciated, cheers, Filip
