Something very special for this week’s Grand Seiko Wednesday. I finally got the correct tools to be able to safely remove the case back of my 4580-7010 VFA, and I think you’ll agree it was worth the wait.
Just look at that. Absolutely no debate that this watch resides at the pinnacle of the entire vintage Grand Seiko collection.
There is a lot of confusion “out there” regarding the use of the 4520 and 4580 movements in the Seiko Astronomical Observatory Chronometer and the 4580 VFA’s. Next week I will do a proper write-up that should clear up any questions. For now, just sit back and admire this incredible movement.
