It has been a while... Here is my watch up close

I am always astounded by the level of detail and precision we can achieve in manipulating the minerals earth provides to produce something as elegant as a mechanical watch (yes, I know this is spring drive but it is still 99% mechanical).

Your images with 4x objective through the thick protective synthetic sapphire at the back of watch are looking good. With a 10x objective you will certainly see significant deterioration.
Really impressive watch with a price tag of a rolex or omega.

Thanks. The real crazy thing is the Japanese... This watch is supposed to have an accuracy similar to a quartz watch: ±15 seconds a month. Thing is, it does not do that. It is closer to ±1 second per 2 months. Spring drive is pretty cool.

Great images of a wonderful subject!! The precision and workmanship at this tiny detail is quite amazing.

Agree with Saul, your lighting is superb!!

Best,

Mike

Wonderful images!

From what I read at https://grand-seiko.us.com/about/moveme ... rive/9r66/ , the time-keeping mechanism actually is a quartz watch, with the 32,786 Hz reference signal generated by a quartz oscillator using electrical power derived from mechanical movement instead of a battery.
Spring Drive is a unique watch technology that combines the power derived from a mainspring with the high accuracy of an electronic watch. Like all other mechanical watches, Spring Drive uses the energy generated by the movement of the wearer’s wrist to move the hands, but it also uses this to create electrical energy that powers a unique regulator that is up to ten times more accurate than any traditional escapement.

The Tri-synchro regulator combines three types of power:

1. Mechanical power (to generate and store energy in a mainspring)
2. Electrical power (to activate an IC and quartz oscillator)
3. Magnetism (to apply a brake to the hands via a rotor/stator)
Further details at https://grand-seiko.us.com/about/movement/springdrive/ . It's a very interesting hybrid system.

acceptable loss/gain for a high end mechanical watch movement is -/+4 seconds per day
For a high end quartz watch -/+2sec per month!

A Grand SeiKo can achieve +/-10sec per year.

Yes - but only the synchronization logic. There is still a spring that winds down and moves the hands. The quartz crystal just drives the solenoid that slows down this unwinding. Best of both worlds.

I still prefer "Glashütte Original", although I can just afford a Swiss-made ETA-Caliber, processed in Glashütte by Union...........

The precision of such watches does not really matter..........

I like the Grand Seiko!
