A high percentage of watches of the vintage of your Omega had vitreous enamel dials on them. Basically, opaque glass power sifted onto a copper substrate, and fired in a kiln at about 1200° F for about an hour. The glass particles melted into a molten state, ad flowed smoothly over the copper surface, leaving what is called a “vitreous lustre”.The dial was allowed to cool, then the numerals, minutes chapter ring, and name were either stencilled, silk screened, or pad printed using finely powdered black glass, and the dial fired again. Then the dial was mounted off centre in a lathe, and using a diamond cutter, a hole was cut for the seconds bit. It was produced just like the dial was. Then, the seconds bit was placed behind the dial, in the opening, and soldered in with bismuth solder which has a low melting point. In several hundred years, a vitreous enamel dial won’t change..........unless the watch is dropped! The enamel is brittle, and can crack. No shame in having hairlines in the enamel dial. If the watch was a car, it could have several hundred thousand miles on it. Stuff happens! If anybody ever pooh poohs you’re Omega, tell ‘em to write their opinions on paper, and put it where the sun don’t shine! No shame! Many of us have watches with hairlines in the dials, and we cherish the watches, anyway. (I have a 104 year old Waltham Crescent Street that is far worse than your Omega, and I cherish it for the story it tells.)
