Hi all.

I am about to embark a service of an Omega Seamaster 300, this will be my first look at an Omega, anyone got a link to a service/Technical Guide for this model.

Thanks in advance.

Paul

They’ve been making this model on various forms for over sixty years. 
 

Is it are recent one, or a classic 166.024?

Not sure yet, I have been asked to service one for a friend of a friend who wants to sell it.

I know who risks a watch of that value to a friend of a friend 😂 especially one like me who has only just started servicing and repairing watches.

Will let you know the exact details when it arrives.

Omega Seamaster 300

One of the problems for tech guides are we need a model number of the watch movement not a generic model number of what looks like a sizable series probably of movements based on the link below.

Maybe we could just ignore my paragraph above if I read the fine print it looks like the movement is this OMEGA Co-Axial Master Chronometer Calibre 8912..

But? If you start looking around they been making them for a long time which means that this was not the only movement which is good for you. The older movements like these 565 is going to be a lot easier to find a tech sheet then today where they're all hidden behind a firewall owned by Swatch group. So anything modern in high tech you not going to get a tech sheet for unless you have a Swatch group account which you probably don't. Then even if you a Swatch group account it has to be at the righg level to see the technical documents at least from Omega. In other words the right access gets you the technical sheets for the movements the wrong access only gets you the technical sheets for casing components.

So you basically have to wait to get the watch to see what the movement number is to see if we can find you a tech sheet.

If it's fairly recent it may have a co-axial escapement - the oiling of which is tricky (you will need a microscope)

The Microscope is no problem, I do all my watch work under one, I suspect not knowing what a co-axial escapement is might be a bigger problem, what is it and how is it different to a normal escapement.

That's not a problem it doesn't slow anyone down on this group  their lack of knowledge of whatever they're doing  sometimes

Then you're lucky? Coaxial isn't a problem sort of  you just need some documentation that you normally wouldn't be able to get? At the link below cousins has some this is a tiny fraction of Omega working instructions  you want to get at least two of them while you're here the first one is Omega Working Instruction 40: Rules for Lubrication (1334KB). Then keep on going down the list you need Omega Working Instruction 54: Checking the Co-Axial Escapement Functions (981KB)..

Then it be really nice to have an actual caliber number of what were dealing with because this watch Manufactured over quite a bit of time in the not all coaxial.. If you're lucky it's older and cousins might have a service bulletin if it's newer well Do you really need a service bulletin?

If it does have a co-axial escapement, then you simply MUST get pictures!  They're fascinating!  I watched a video wherein George Daniels lectured about it.  The concept and the action of the thing is amazing to me.  So little friction that it barely needs any oil (hence the microscope).  I've not seen one in person, but have watched plenty of videos.  I will be so jealous if you get to work on one.  Those kind of Omegas are really nice.

They surely are. But as it happens, Omega was first reluctant and then applied modifications to Daniel's that left him upset to say the least. After many years of production it didn't proved to be a big enough progress or market differentiator, and nobody else so far has adopted it.

Strangely enough the coaxial escapement can bring bad memories to me? This is because when I went to the wostep reunion George was supposed to be the speaker but he refused to speak and didn't even show up at all because he was pissed off at Omega. The basic story is that I'm not sure if he actually worded it this way that they mutilated his escapement. Because after all he designed a escapement that used no oil at all and now it has oil. Of course the amusing aspect is that oil isn't for lubrication. But still it's there And George definitely was not happy at all.

Ah, I had not heard about the falling out between master Daniels and Omega.  To hear him speak, he seemed very pleased with his invention.  And Omega had seemed happy to be the one using it.  But I was unaware of any bad blood between the two.  What you say, however, of Omega's interpretation of his design does explain why nobody else seems to be using it.  I'd wondered about that.  Pity.  As conceived, I think it's fascinating.

Coaxial movements by Omega are very popular aren't they? I doubt they'll appear in other Swatch brands as they will want to keep it 'high end' (maybe Breguet?) 

Seiko (Grand Seiko) have something similar:

    • Hi Watchrepairtalk, I have some questions about part sourcing I was hoping someone here might be able to help with. I'm working on an FHF 180 movement with a broken balance staff, broken regulator pins, and damaged cap jewels (both top and bottom). Some Googling says that this is similar to other FHF calibers like 150s, 160s, 180s and so on but I can't figure out what the functional difference is between these movements.  Is there any reason I wouldn't be able to acquire a donor FHF 150 or similar (with no shock protection) and use parts from that or would it be smarter to source replacements individually? Also are there any sources someone could recommend to get bulk cap jewels like this? Thank you for the help!
    • Hello and welcome to the WRT forum.
    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.
