Seiko

Credor brand was born in 1974. To commemorate 25th anniversary of its caliber 6870, Seiko's ultrathin movement, Credor will launch super dressy models, dial hand made by Urushi Master Isshuu Tamura, who did Raden as well as Maki-e for those models. GBAQ95...  

But are those tolerance figures correct? +25 -15 seconds seems like quite a large tolerance for a brand like Credor.

Ken, It's difficult to put a value on Art but USD22,500 before taxes is a fair chunk of cash. I like it but you know my weakness for urushi and raden. Regards, MTF L.U.C XP Urushi Ultimate Universe ...  

.. especially who can work on such a small "canvas"..... It's getting more and more difficult to make these in quantity....thus more expensive.... )

I have the related predecessor movement - the 6810A - in my Seiko 6810-8000 and it’s a nice piece of ultra slim. And like here a rare case of a shaped movement in a round case

It certainly is an interesting brand
