Seiko

While I would love to have an Eichi II, I just currently can't justify the expense.  I did find this model GCLP993 though which uses a different (less decorated but still nicely finished) manual-wind Spring Drive movement, the cal. 7R87 and can be had for a much more modest sum than the Eichi II.

Still not 100% convinced on Spring Drive longevity though as it's got a quartz component.

What kind of timeframe are you concerned about? If you’re thinking of your grandchildren passing it down to their grandchildren then possibly you may have a point, but I’d suggest there are more significant things that come into play over that kind of period.
Seiko first started producing quartz watches in 1969. Sure, the earliest of the early pieces can be troublesome, but once you get to the mass-produced models starting in around 1972, they are extremely reliable (despite their now almost throwaway value), and spare parts cheap and easy to come by due to the sheer numbers produced.
Kind regards,
Gerald.

whether they will be able to be serviced or find parts for in the future will be the question. With purely mechanical movements a "good watchmaker" should be able to fabricate parts. With plastic electronic or circuit board pieces can the same be said? Doesn't matter if it's 10 or 100 years from now. I have a couple of 70 year old JLC RAF Mark 11s and a 65 year old RAAF version which can still be serviced by competent watch makers. Same can be said for my 1959 IWC Ingenieur. 

Definitely wish list quality
I would go for it!

Feel free to skip over the wordy part; looking back I see I was rambling a bit.

The last half of the article shows some other variants to the Watch you’ve found.

I like the really clean and simple dials. This model is probably as close to the Eichi II that Seiko makes at the moment.

So this alternative with an MSRP of $7,500 might tick all the boxes I need at a fraction of the price.

The combination of Credor - SpringDrive - Big Date - hand wound made this an easy pick for me. Size of the case, the classy look and refined case with this enamel look alike dial sealed the deal. Outstanding are the hand tips and I dare to say that the bridges seem to have a bit more (rainbow) luster than the GS’ and the decoration is slightly more refined. Having said that, given the early generation of this caliber (which i believe the Eichii II uses as well besides different, lightyears apart nicer decoration), the winding is not as nice and smooth as the current ones and you have to live with a 2d PR. But by all means, a beautiful watch!




















PS: completely inadequate is the relatively flimsy folding clasp (which is anyway a wrong choice for such a dressy watch) which was replaced by a pin buckle

Thanks for these excellent pictures. There isn't so much information around on this one. I have been making a few enquiries as I would like to add this one in the future. Yes, the movement finishing is a step up from GS. I have a manual wind GS and a Spring Drive. But to have both in this beautiful, almost playfully elegant juxtaposition would be wonderful. 

These real-world pics really show the true beauty of the watch.
