GMT 1675 Dials

Below are some photos that I have put together regarding the progression of the GMT 1675 dials from the various eras of production from 1960-1980.

Since I do not have every GMT dial variation in my possession, I relied on the internet for some of the photos which are depicted here.

The gilt (or gold font dials) era for the GMT 1675 began with the original model and continued until it was discontinued around 1966. There were a few variations of the gilt dials with the early ones reading SWISS at the the bottom and the last ones from the gilt era with SWISS - T 25 printed at the bottom. There were also variations with the SWISS dials. There were the early "exclamation point" dials which looked like an exclamation point at the number six marker (see photo G-1 and G-2). There was also another variation where the dial contained an underlined score directly beneath the OFFICIALLY CERTIFIED font and the circa 1964 radial dial with the double marked SWISS identified in the G-rail photo below. The exclamation point dials and the underline scored dials would probably be considered the rarest of the gilt era dials. (There could be some other variations that I have over-looked.) Most of the gilt dials all have a distinct coronet which helps identify them further. Below are photos of the gilt dials identified as G-1 through G-6 and what I believe is the progression of the dials.

The dial marked G-5 or G-6 was the last variation of the gilt dial and the G-4 preceded it. G-1 seems to be the earliest gilt dial and the G-2 and G-3 fell somewhere in between.

After the gilt dials, the printing became white on the GMT dials. Each era for the various white dials found on the GMTs is easy to identify by the coronet printed on the dial. There are also luminova/super luminova service dials that contain a very distinct dial coronet and are marked SWISS - T 25 and or SWISS at the bottom (the dial coronet is the same on both dials).

The white dials are identified below as W-1 through W-5 along with a photo of the GMT 1675 service dial. The dial marked W-3 is what is commonly referred to as the "radial dial" made for one or two years during the mid 1970's. Dial W-1 was used during the late 1960s thru 1971, W-2 followed next for a few years, then W-3 for a couple years and the same for W-4 and W-5. It appears that during the 1970s, the dial was changed every two or three years. I do not want to place exact dates on the production era for each dial variation but instead prefer to show the progression of the dials.
