I'm happy to present to you the mysterious watch after the treatment by Master Abel.
Here is a "before" picture for comparison:
Five months went by between these images - certainly worth the wait.
I opted for a moderate restoration without replacing any parts.
The case had to be refurbished, of course. We assume that this G model resembles the well known A3817. Abel managed to regain the original shape, lines, character of the watch - despite the great amount of material this case has lost over its lifetime (the lugs were missing millimeters, compared to the steel case). It's amazing how Abel feels these three dimensional shapes while also caring for perfect symmetries.
The dial was cleaned. The most tricky and dangerous task was to remove the old two component luminous material without damaging the indices or the dial. Even during this demanding phase Abel allowed me to feel like looking over his shoulder by continuously sending me up to date pictures of the dial. The chronograph second hand was re-lumed, too. Now the indices perfectly correspond to the fine main hands with original lume. The face simply looks right, nothing disturbs.
I'm not able to describe the numerous additional tasks Abel had to carry out on crystal, gaskets, crown, pushers, back, movement, etc.
Thanks again to Abel for this excellent work and the perfect communication. And thanks to the contributors of this thread, who supported this very special project.
Cheers,
Mick
