Restoration of the Pulp Fiction watch

Hi everyone
maybe some of you already know my YouTube-Channel "Red Dead Restoration". I´m restoring old things, mostly watches.

This is the first of (hopefully) many more posts to come about my restorations.
Basically you can find some informations about the restoration-process on the video description on YouTube but I want to share some more in-depth insights with the community here.
If you have any questions, feel free to ask. I will try to answer all of them ;)
Let me know if you like the idea (and of course the video).

So starting with my latest release:
"The Pulp Fiction watch or ... the gold-watch that was hid up his a**"
This World War 1 Trench-Watch was made by Lancet. The movement is an Adolph Michel 220 hand-wind movement with 18.000A/h and a power-reserve of 31 hours.
I´m not able to say when exactly the watch was made but based on the movement, the enamel-dial and the radium-filled hands my best guess is somewhen around 1920.

This watch was featured in the movie "Pulp Fiction" by Quentin Tarantino. It´s the watch of Butch Coolidges (played by Bruce Willis) great-granddaddy.
After the war, Capt. Koons (played by Christopher Walken) is giving the watch to the little Butch and he is even risking his life just to get it back when it was leaved in his apartment.

I´m adding the Monologue of Capt. Koons here:

"This watch I got here was first purchased by your great-granddaddy. It was bought during the First World War in a little general store in Knoxville, Tennessee. It was bought by private Doughboy Ernie Coolidge the day he set sail for Paris. It was your great-granddaddy's war watch, made by the first company to ever make wrist watches. You see, up until then, people just carried pocket watches. Your great-granddaddy wore that watch every day he was in the war. Then when he had done his duty, he went home to your great- grandmother, took the watch off his wrist and put it in an ol' coffee can. And in that can it stayed 'til your grandfather Dane Coolidge was called upon by his country to go overseas and fight the Germans once again. This time they called it World War Two. Your great-granddaddy gave it to your granddad for good luck. Unfortunately, Dane's luck wasn't as good as his old man's. Your granddad was a Marine and he was killed with all the other Marines at the battle of Wake Island. Your granddad was 
facing death and he knew it. None of those boys had any illusions about ever leavin' that island alive. So three days before the Japanese took the island, your 22-year old grandfather asked a gunner on an Air Force transport named Winocki, a man he had never met before in his life, to deliver to his infant son, who he had never seen in the flesh, his gold watch. Three days later, your grandfather was dead. But Winocki kept his word. After the war was over, he paid a visit to your grandmother, delivering to your infant father, his Dad's gold watch. This watch. This watch was on your Daddy's wrist when he was shot down over Hanoi. He was captured and put in a Vietnamese prison camp. Now he knew if the gooks ever saw the watch it'd be confiscated. The way your Daddy looked at it, that watch was your birthright. And he'd be damned if any slopeheads were gonna put their greasy yella hands on his boy's birthright. So he hid it in the one place he knew he could hide somethin'. His ass. Five long years, he wore 
this watch up his ass. Then when he died of dysentery, he gave me the watch. I hid this uncomfortable hunk of metal up my ass for two years. Then, after seven years, I was sent home to my family. And now, little man, I give the watch to you."

This watch was in a really bad condition. The gold-case has tarnished and was heavily scratched, one of the case-lugs was broken, the glass and the sub-second hand was missing, the hour- and minute-hand was corroded and the movement wasn´t working.

I´ve bent a new lug out of a 1mm brass wire and soldered it on the case with some silver-solder. Finding the correct temperature for soldering wasn´t easy for me, it was the first time for me that I´ve soldered anything.
After sanding and polishing the case, I´ve realized that the case was gold-colored and the bezel silver. So I´ve decided to gold-plate the bezel to match the case.
I´m using a graphite-anode and around 4 volts on my power supply.

I´m removing the radioactive radium of the dial and the hands, after re-bluing the hands I can add some new non-radioactive luminous-color to them. A drop of coffee ads a "vintage character" to the luminous-color.
The re-bluing is a tough process. The hands must be polished and cleaned. Heating them up to 300°C makes them cornflower-blue (10°C more or less will change the color)
A little crack on the dial will remain, covering it with new enamel will kill the originality of the dial.

I need to replace some parts of the movement to make it running again. The bearing on the trainwheel-bridge was damaged. Because there are no jeweled-bearings on the bridge that I can replace, I need to replace the bridge completely.
Unfortunately I wasn´t able to source a one-piece bridge that´s why I used a two-pieced variant.
The movement gets a new mainspring and I need to straighten the gear for the sub-second-hand.

After everything is cleaned, polished and re-plated, I can re-assemble the movement with some fresh oil. After that, this watch is in a fantastic beat (+2 seconds per day) again.
