And more research.

Putting the Lovely Landerons aside, I wound up getting more omega spare parts from an online estate seller.

As I have noted in other threads, I am a sucker for estate sale parts assortments. I have been collecting parts as well as watches for over 30 years.

Recently I got a 505. 505 caliber watches are not the same as 550 watches. These use a base caliber of 500 which is a base caliber of 470. But apart from a few parts shared with 330 the sizes are all wrong.

Still I am finding patterns in the chaos.

By chance a loose seamaster dial fits the 505 mainplate (but the dinamic dyle does not.) I also had quite a few parts for 330,470, 550 and others. I do have the 'parts' book what covers these calibers.

The floppy drive box,I have used to store this stuff for at least 24 years, is now too small for all the parts and will no longer close. Guess it will be time for a bigger box.

Did find a few parts useful for the 505. And even breed a couple.



The 505 balance did not turn free when I got it. The bridge screw was rusted. Fortunately it did come out with little effort. The balance pivots looked good. Reassembling it and it now swings free.

This is where research comes in. I may have posted some early impressions in one of the what did you get at auction threads. About 1/2 the parts are missing. At first I though some of the 330 parts might work, No luck, only a few setting parts are in common.

Likewise none of the 550 parts are compatible. I also learned that 562 and 563 parts are different. All by comparing data sheets and reading posts here.

Some winding parts were also missing. I was thinking of posting as there is much written on how 550 winding bridges and gears work together. Notably bridge 1033 was a puzzle. Especially as most of the steel parts and big wheels are missing. Without an assembly guide it is hard to know how things fit together.

I can see the fuzzy pictures in the data sheets. So I do know what is missing. More searches and I find that @Mitka Had just the picture I needed posted somewhere.



So now I know where the missing parts go.

Half the barrel is missing. This part seems to be all or nothing. Given the amount of rust on the plates I suspect there was major water damage happening. Some of the wheels are missing pivots. I think on the dial side.

What was strange, was that when I put the unused parts back, into the now too small floppy drive box, I found I had two center wheels. Yet there was only one center wheel in the auction photos. There were two third wheel assemblies in the auction photos. So where did the other center wheel come from? Must have been loose in the spare parts, fallen out of an envelope or something.

The winding stem is another mystery. I have lots and lots of stems. One would think as much of the setworks comes from the 330 that stems would interchange. But no. A 470 stem does not fit a 505, and niether does a 550 stem which looks different than a 470 stem. Only through much research can such be figured out.

And here I thought Landeron differences were subtle.

Now comes the waiting. There is no escape wheel. Most of the listing are sold out on the part. I was going to call the parts houses to see what missing parts might still be in the dusty warehouse. There was one seller in Spain who had such listed. Since I watched it. I got an offer, which was less than the material house would likely charge.

I never think to look at the parts for sale here. Mostly as it seems to be accessories. On the other hand much of my research here in these forums, answered most of my questions before I could ask them.

In a lot of ways, I want to share every little detail of discovery. It is always so satisfying when one does find a match with a part or piece of information. There is so much out there even when one keeps getting asked by google if they are a robot.

After weeks Of waiting the 552 movement showed up.


The dynamic dial does fit. And the movement fits in the dynamic case. Which it should according to the charts. The hour had which was sold as 565 seems too large. Dynamics also used the 1022 caliber. Which actually seems to have smaller diameter hands. The hands I got actually look like my chronostop hands. The chronostop is 865 which is the same family as the speedmaster. Curiously the Lemania 1280 that I have takes a similar sized hand. I checked the eBay listing and the hands are supposed to fit a 565 dynamic.

Typical of eBay -- sellers simply sell what is on the package. The hands do look right for the dial. May have to bush them.

What is left of Ranfft says the sizes of hand are
1422 130 060 022
505 150 080 018
550 150 080 018
865 190 105 022

The omega charts give a tolerance for the hand holes.

I have not found any charts for dial feet positioning. I can confirm that 500 series dials are not the same as 550 series dials.
My preference is for no date watches.
hands are the same, however the canon pinion and sweep pinion come in different heights.


Disassembled the 552. It is really dirty.



The cannon pinion was rusted and the seconds pinion impacted in it. Broke the minute wheel arbor attempting to pull them off. By chance I have another minute wheel, but for a 560. I also have a sweep pinion for a 750.

I think the minute wheel is the same on all these The sweep and cannon pinion come in different heights. There is some nice charts in the books for these.

Balance looks good. The watch would not run due to the impacted cannon pinion. The top is completely sheared off.

The mainspring looks to be in good shape. I have had a spare for decades. Will probably use that one as it is easier to wind the spring into the ring.

By chance I also have some split stems for the 550. Not sure they are the right length for the dynamic case. Looks like I bought an assortment of gilt split crown some time or other in the last decade. The dynamic case came with a crown.

I also have the two seamasters what need cleaning. One has an obvious redial. So I might borrow parts to get this dynamic going.

Too bad the 505 will not fit in a 550 case. That is shaping up to be a really nice movement. It is disappointing that the dynamic style hands seem too large for the 552. They may however fit my Lemania 105 which could get interesting.

Thanks to a kind person here I got the 505 parts that may get that ticking soon as well. May be tricky to replace the pallet fork arbor.

This does show that research does pay off. The goal of this project is the Dynamic. And I am glad I now have the right movement for the dial. As well as a movement for the other dial.

I have hardly even started to touch the ladies versions of this. I did get another 684. And a ton of date mechanism parts. (someone else got the date wheels)

And there are always Landerons to play with too.

Probably should put all these into separate threads. While waiting for the 552 movement I got the 1342 quartz. It did not work, but swapping the circuit board did make it twitch. So the research there was succesful too. This data is out there if one simply takes the time to look for it.

More photos:
I assembled the watches with as much parts as I have to see how the dials fit.

The 505 is still missing the escapement. And does not have the winding wheels in the bridge. The movement is also a few mm or fractions there of too large for the case. I could try shaving the case down. For the full Victor F. experence. Not sure if the weight would rubb on the case back. I still do call this wach movement "lucky."

The 552 would probably tick if it had a mainspring in it. The cannon pinion and sweep pinion are to tall. The hands fit loose. They are too small for the lemania 105. So they remain a mystery. They do look OK with the dyle and the lume is a good match under UV.

The dyle was always cracked. Not all that noticable in regular light. Split stem may be a bit on the long side. Probably need to make one of those wedges for the stem.

Sweep hand will be a challenge.

Next step is to pull it apart again and etch the broken dial scres out with alum.

I may borrow the cannon pinion from a 550 seamaster (which I should clean anyway.) I have had that watch decades and never worn it. Not a fan of gold colored cases with spindly lugs.

May try bushing the hands with Kapton tape as a test.

I really need to get my lathe working. (well the swing over stereo microscope.)
