Question about 14060 and fonts on dial

[erolorhun]

Hello,

I`ve been looking for a nice 14060 for a while and have been noticing that some No Date Submariners have the "SUBMARINER" on the dial written in a different font than other 14060s. This is especially visible in the "S" where the top and bottom parts is flat rather than curved upwards respectively downwards.
Asked a Rolex-knowledgable person and he hadn`t an answer. Does anyone here know which 14060 have this more modern font and when Rolex started with this? Is it perhaps a feature on the 14060M visavi the 14060?

This one is featuring the "traditional" font...:
