Omega 105 Tool 'accessories'?

Hi all-
I have an Omega that requires a 105 tool for crystal removal, so I found one on ebay. I figured I could use a cheap crystal squeezer, but this seemed like a good reason to get the 'official' one.

HOWEVER, it came with 2 accessories, both with the 105 marking on it, that aren't clear what they are for? They seem to go into a separate device, and neither fits my watch it seems. Thoughts?

Additionally, and more of a brag, I picked up 20 of the 28 Esembl-o-Graf books on ebay! Seller had all but a couple of missing ones in the middle, so I was really happy to pick them up! I also have a digital copy, but enjoy paper versions myself. I have a Landeron 48 I want to start working on soon, I pulled it apart today and realized it has a busted balance staff, so I might be doing my first balance staff on it!

I purchased a tool 105 a couple weeks ago on eBay. The stupid seller sent me a tool 107 (which I already have.) So you are lucky. I had to return the one I got as the seller would not exchange it.

This style is used on the smaller dress and ladies watches. So I think the adapters are for handling these variations.

I have had a set of ensemble graph books for years. Most of these are online. My set is also missing some issues. The online stuff makes for a way to see if they are useful or not. Note that the part numbers are not the standard ones used in the data sheets.

Landeron's are great watches to learn on. There is a lot of subtlety as they were often 'upgrading' some of the springs and levers that often failed. There are at least three variants of the minute recorder jumper. Some also had an incabloc shock system. The balance bridges are not always interchangeable. I think they were sold in a way that the finisher could fine tune the balance.

Get yourself a good poising tool. Also be super careful of the hairspring.

I also recommend starting with a watch running and in tip top shape. Starting with a wreak only leads to frustration. There are often multiple points of failure.

As far as the tool... it isn't clear to me how those things would be put anywhere. It almost seems like there is some sort of 'base' that I'm missing that those are supposed to 'click' into.

Anyway, I have a while until I'm brave enough to move my watchmaking onto the Omega, I'm mostly just doing seikos where I can order replacement parts when I screw it up too badly.

Re the Chronographs:
sigh yeah, I've had a few watches apart for servicing now, and am doing... ok. I picked up the Landeron 48 pretty cheaply so I was going to give it a shot. For the most part the idea is to have something I can take apart to learn a chronograph.

I've already discovered there are multiple balance staffs, as mine has a broken pivot I'm going to have to try to figure out if I have the right one ordered, AND if I can actually do the job. Its an education 😀

Ah,thanks for the confirmation! I'm guessing I'm missing whatever 'holder' they are expected to go into then.
