Great story and beatiful watch!
Can somebody please explain to me, why below "Tachymètre" and "Telemètre" The dial has another shade of white?

A friend once had a similar experience. He serviced a chronograph with a similar dial with a royal blue background. He gave the dial a “swish” in soapy water, rinsed it, put it to dry under a UV light to dry, then forgot about it! The customer wouldn’t accept a sky blue dial.
