As far as I know, L. G. Breitling s' subcontractor for those fine pitch dials used on Navi's and Chronomat was the company Linder AG .
You don' t speak of the electric soldering of dial feet at the beginning.
"Painting" is not the best word for describing the technology used for printing scales and their numbers ,texts as Navitimer - Geneve - Tswiss made T , etc , and lume too . It is the "ink tranfer marking " technique , : 1 pattern/ color = 1 transfer , possible accuracy around 5 microns .
Basically the pattern is applied by chemical etching on a finely polished SS plate . Ink contained in an ink tank is applied in the pattern using a squeegee .
Then the transfer is made by pressing a silicon pad on the inked pattern , then pressing the silicon pad on the dial to be printed . Extreme accuracy in position and pressure allows a perfect transfer of ink on the dial . It is used for printing scales, numbers, index, brand, lume . 1 pattern/ color = 1 transfer .
Thanks Phil,
It was never my intend to write about the dial feet.
There's no doubt at all that you have a much deeper insight about this process then I do, and I must admit that I was considering asking you for advice before I wrote it.
I wanted to make it easy understandable, and as little technical as possible, simply write about the process from a superior point of view.
I have uploaded it to my website, and I will appreciate if you with a few words can make any corrections that is needed, without making too many deep explanations, it will then be corrected according to you, will you do that ?
