Hello folks,

First post to say hello, lots of very knowledgeable people and information here , a great site so thought i would join up.

Just starting my journey of discovery with watches, after a lifetime of mechanical engineering and taking things apart. Charged and found guilty of disassembling a Stanley hand drill chuck aged 7, apparently it took me 2 hours to put it back together, so i have form if nothing else.

I currently have an Omega Seamaster Deville (Caliber 562) that I am looking at servicing. I am taking it very slowly, reading lots and trying to gather from others,  I am humbled by how much skilled people are willing to share here.

Kind regards to all

Welcome Hilts, Unless you have some experience with servicing watches I would first attempt a less prestigious and valuable watch before the Omega. It can go terribly wrong very easily.

Enjoy the forum.

Hello Hilts and welcome I would agree with @clockboy find yourself a couple of cheap working automatic  movements first. Strip them and rebuild them to a running state. Don't rush into such a nice movement because its there. Take your time and get to grips with your tools first handling parts with tweezers takes a while to master.

Hello and welcome, your best bet in starting out is get hold of a few pocket watches (not fusee's) and just keep taking them apart and putting them back, don't matter if they don't work, get to know the names of the parts, they won't be automatics but you will learn a lot, there just like a watch but much bigger, what you have is a very expensive watch and is classed as a high grade watch movement, its a hell of a step jumping in on something like an Omega, its like jumping in water and swimming but you haven't learned to swim. There's loads of advice on here about the sort of tools you will need as well.

A warm welcome to the forum Hilts.  Your background, including the juvenile overhaul of a Stanley hand drill, is almost identical to mine.

The advice you've received already is very sound, I too would stress that you do not make a 562 movement your first victim.  Here is a link to a topic relating to a 561 movement I serviced a while ago.  This will give you a good idea of the complexity you will have to contend with.

Thanks for the replies folks.

 I guess i was hoping for a "give it a go son" post in reply, but your collective wisdom is too much to ignore.

I have a couple of books under my belt and a couple of Doanld de Carle's coming, whilst i collect tools together.

I am spending a bit each month and having a lovely time selecting. I have also been wowed by the watch repair channel on you tube and low and behold it seems to be Mark on here so kudos and respect to him. I take your point about tools and was cognisant of this when watching one of Marks video's as I observed him approaching parts to pick up with tweezers closed then opening them to the required size which struck me as quite sensible but not something i would have done naturally.  

Geo thanks for the link, wonderful. I also saw  canthus's thread on the similar Cal 552  and the excellent tool they made for the reversing gear assembly, this has inspired me to do the right thing and get some simpler movements to practice on .

Thanks again to all.

Hello Hilts and welcome from me.
Glad you have seen the light. Always best to take it slow. Don't forget to take a pic before and after you remove each part and you will always have a guide on getting things back in the right place.
Cheers,
Vic

    • Hello, I recently bought a Brenrey watch cleaning machine. It is in really good condition but the motor speed control is not great. The motor start at relatively high rmp, it can go faster but not slower or stoped by turning the knob. I think it is the rheostat but outside YEC F-50 there are no other markings on it. It measures 1550 ohms max resistance.  Does anyone know what should be the specs of a rheostat or potentiometer to replace it? Thank you in advance.  
    • Interesting, thanks for the detailed post. I saw one of those Swiss Nano machines a while back in another youtube video from  the Weiss Watch Company.
    • Hello and welcome to the fo4um. Enjoy
    • Welcome to the forum, enjoy.
    • You're asking a pretty broad question and you didn't specify the machine but yes it's simple especially if you have the right machine. The question has problems but I'll take it as it is. Is it really that simple yes especially if you have the right machine. So in the video below he's making a screw and yes it really is that simple but pay attention to the machine it is not simple at all probably wasn't cheap but it is small it will probably fit in your garage. Unfortunately wouldn't fit in my garage as it's far too cluttered up with things. In the video he talks about making a screw and pay attention to the machine. The machine has lots and lots and lots of cutters and lots of things to do lots of machining all-in-one machine conceivably one step after another all programmable. If you look at his channel lots of CNC's stuff and there are several other videos related to this machine. He goes to the factory where they talk about it and show all the other machines they make in Switzerland.  I did look up the specifications the machine I don't recall the price it's not going to cut wheels I think it has a maximum diameter around 11 mm basically it's really good for making small diameter watch parts. Then in one of the other videos he goes to a factory that used to make parts with waterpowered machinery been in business for 100 years and everything they now make is made with CNC machines including this one. What was interesting with the factory photo was that when they make some parts they can put them on a optical comparator comparator compares with whatever the reference is and the machine can be programmed to adjust its cutting to make sure everything is actually being made to specifications. Oh and then somewhere in all of this there was at least one picture of a balance staff can't have a CNC Swiss machine without making balance staffs.   It would be really nice if we had pictures of the machine. Then yes if you look at the page for wheel cutting you can enter parameters and it will generate a G code but he left out things? Notice he has a picture of a complete wheel but the G code isn't making a complete wheel it's only cutting the gear teeth I don't see whereas the program for crossing out the spokes? Typically when you see people cutting gears once the teeth are cut most the time the spokes are cut by hand. Occasionally someone will mill them out but typically not with the program which seems strange if you have CNC capability for instance one of my friends fill it used to design assembly line equipment or things to make things. So his hobby was to continue to make tools to make things like clocks. Very interesting and clever clocks but his true fund was making the machines to make the clocks. Then machine is not controlled by G code like we would typically find today as the stepping motor controller he has was made a long time ago and the individual controllers used a textbased program. So the company had a editor you could write a program to cause each the stepping motors to do something. So basically once you figure out how to cut a gear he would just change the parameters for different size gears so here's an example of a gear as you can see we have the teeth and the spokes. Then we have a picture the machine which sucks because it would've been so much nicer if I could've taken a picture when it was cutting a gears so we can see things better. Then yes there is a worm gear stepping motor indexing this is a mini lathe and the indexing is at the end of the lathe head hiding. The basic operation of this machine would be brass sheet not cut to a specific diameter size not even round mounted on the machine. Then it turns and a milling cutter will cut the diameter. Then the gear would be cut with a gear cutter. The same mill cutter for the diameter although conceivably change the size I don't know but basically the same milling for cutting the outer diameter would be used to cut the spokes. I really can't remember how he did the center hole but whatever it was was very precise.
