It's been several questions about watches not followed by pictures.
I wish that every question, about a specific watch, should also be followed by a pic!
We can't get to many of them, and without them it's nearly impossible to answer some questions.
Even pics that actually doesn't seem to be about the things that are actual discussed,
are often essential,
they always makes a thread more attractive!
Sooner or later they will be a treasure, when someone looking for a detail suddenly stumbles on it!
So please, let all your questions be followed by a pic ,
that's nearly a prerequisite for an accurate answer.
This is a Vacheron&Constantin from 1937, a year that the whole year-production were 439 watches !
It's also before they had started putting numbers of the different types of movements,
they only was named after their measure in lignes.
One ligne = 2,255 mm.
This movement is 11 lignes in diam, or as it is written 11''' .
Brushed roségold and applied yellow gold indexes.
