HI, Here is a dial which has become known as the Mark 0 dial, which is a white-lettered fonts dial, found on the GMT 1675. It is believed to be the earliest variation of the GMT white-lettered dials with the dial coronet appearing to be very similar to the last variation of the gilt GMT dials. Watches with this dial are often found , and correctly I might add, with the small 24-hour hand. any suggestions? Please help. I didn't find the right solution from the Internet.
