Isn't that the Daymatic (which I prefer to the L1)?...
...but I know what you mean. Same L1 layout with an auto movement...would be interesting and pretty easy to do.
Lange is big on the equilateral triangles.
Educated guess that it is indeed a Lange 1 variation, but no information provided on the hands themselves. So I'll guess a 12HR second timezone hand with a day-night indicator, similar in execution to the Jaeger LeCoultre Master Hometime.
Agree
1 clearly a sign of day night indication It would be a combination of Day night moonphase with 1) daymatic 2) time zone 3) Perpetual calendar
Lange 1 Tourbillon?
The first Lange 1 Tourbillon was introduced in 2000 so perhaps it could be a new L1 Tourbillon to celebrate 20 years strong.
