Sa3135 has a pointy 4 on the dial whereas 2836 has a flat 4. The space between ft =1220 isn't necessarily wrong on the Sa3135.
Gen 16600T
Flat 4 on dial matches insert
Here is another interesting example of a 16600T 2006 model
Looks like the dial has the spacing and pointy four seems to match the insert.
What's also very interesting is the second markers under the Swiss Made on the dial. As you can see from the top two examples they do not exist but on this example they do.
I assume ? made a few variations of the dial.
