date ring change on a 2824-2 eta movement


Question

Ok.  So here goes.  After watching Mark's videos and specifically the two where he makes a watch from sourced parts, I decided to make a watch for myself that would not only be a great conversation piece and look good but be made EXACTLY as I like and want and keep good time as well.  So I have the parts all ordered up and some are already in.  One thing I want to do is to change the date ring from white to black.  I ordered one on ebay.  However I am not too sure if it will work on the ETA movement as it is aftermarket.  So there is question number one.  Will that one work or am I going to have to rummage around looking for an ETA made date ring in black?  My second question is, how hard is it to change that in the first place?  I haven't seen a video showing that specifically on that movement.  I am by no means afraid of doing it.  I take safe dials apart for my job as a locksmith and safe technician all the time so mechanical things scare me not.    But I would like some pointers and things to look out for while doing it so I don't screw up the movement.  Obviously when I am done with this project I will post all my pics.  I know you guys like stuff like this.  Its why we are here.  Thank you .

The aftermarket one should be fine. They pop right in and out. There is a little plate with notches that allow the disk to come out and go back in. Just set it in those notches, press the spring in, and it’ll drop in place:

 

This is a Rolex datewheel (upside down) so it’s not the correct fit but you get the idea:

    • It looks like the pinion gear on the escape wheel is absolutely worn out to me 😵     John 🙂
    • I have learned 3 things with the disassembly of my first watch. 1. Watch face retaining screws are impossibly small. On the BFG you have to remove one of them completely to get the face off.  Then, when you tweeze them back into place with a crappy tweezer, the screw torques out and is gone forever.  Use better tweezers and don’t squeeze so hard.  2. When you practice reassembling parts to help memorize it for final assembly, don’t use the work surface to flip over and re-orient springs with your tweezers. As soon as you let go, the spring finds a new home in witness protection somewhere in your workroom, also, never to be seen again.  Perhaps it is neighbors with the dial screw? 3.  This stuff is fun.  I can't seem to find a source for this spring, and I am not dropping 100+ USD for a parts movement. Therefore, I may have to make it.  Anyone have experience with making springs?   Where do I source the spring steel?  I saw someone use piano sting wire to create one.   Any help or advice here would be appreciated.     I have circled the part in the pic below.   -Devon  
    • Ok great. I’m not comfortable getting this “deep” into altering things. I had visions of too much or too little end shake and pulling what’s left of my hair out... Im somewhat relieved that it’s straightforward. I’m still not sure the donor spring I have is sized properly, but I hope so. 
    • Hi, Could someone help me identify this watch movement?
