Sub C Dial Variation

[flv112]

So far I've spotted three different dials. Here are some pics which I found on the internet.

Pic 1 shows the closely spaced 1000ft=300m with long f, the 1 written as l and the italicized equal sign.
Pic 2 shows the closely spaced 1000ft=300m with long f.
Pic 3 is the one with larger gaps between the = sign and the 300 m.

I just bought my Rolex sub c last month and I have the third one in the above 3 photos! I think it's the most easily read due to the spacing.
