The Thor II is a surprisingly rare bird. Although it was of lower quality than the earlier Thor (rolled gold plate case rather than filled, 17J Swiss 686 movement instead of 22J American 770, embossed dial rather than applied numerals), most collectors consider it much more attractive due to the stylized numbers and sharply angled hands which give it strong visual impact. Going through all my years of repair records, I found that I've restored 25 Thors, but only 4 Thor II (including this one). That makes the Thor II about 6 times rarer than the Thor.
This one is outstanding -- near-mint with zero wear issues on the RGP case. Even some of the original brushing on the case back remains intact. I've completely overhauled the movement, installed a new crystal, and mounted a NOS (1980s) exotic Hamilton strap made of genuine antelope. You'd be hard-pressed to find one as nice.
