Case is 26mm x 29.5mm without crown and lugs.
Really sweet getsn and somewhat big for the time. Two tone white with yellow gold scrolling. Somewhat a combination of stepped sides and the wavey sides like a ranger but not that either.
You'll notice the back has a defferent serial number starting with a 5.. as opposed to the inside corrent date serial.
I don't think I've seen this one in an ad yet?
Could be mistaken for the Sky King by the dabbler but definately not that.
