I agree with the OP, the numerals need to go, a la 3F, a great improvement on the 3. Allez le 13F!
It's interesting that the 1.1 was made bigger than the 1, for no technnical benefit (the 7750 is no larger than the 5100), just because they wanted it so.
For various reasons, the 1.1 was a bit of a failure, and won't be coming back, I am sure.
The 1 sold well as one of Sinn's most expensive watches back in the day (over 3000 made in about 7 years), the 1 LE of 250 sold well, and immediately traded at a premium.
Sinn massively upped the price for the 1.1 and they hung around in dealers for way too long, considering that they too were a (less) Limited Edition of 500 - they could be bought new from ADs more than a year after release. That is not a success in anyone's book.
The 1.1s do not really trade at a premium, so are not as well regarded as the original.
Then Damasko came along and offered the DC80, which is 95% of the EZM1.1 for about half the price.
Sinn won't be doing any more.
I would love them to, but they won't offer the 1 either.
