Me again. I have just fitted a new stem to this damn omega. The quick set calander function works fine. Setting the hands is working fine.

But when i come to winding it up it starts to slip as if teeth are missing from clutch or winding pinnion and there are no teeth missing. Ive attached pics incase there is something wrong with the set up that i cannot see.

Any advice suggestions would be a help.

cheers

Just a thought but thinking laterally, could it possibly be an issue with the mainspring slipping? I mean maybe if the barrel arbor hook hasn’t quite engaged with the mainspring hole this may resemble a simple effect.

dose it have an autmatic  spring??   if so,  theres your problem.  i have an omega speedmaster, 1970 that slips just like that..  here is my opinion --main spring is broken or the spring ( on ether end) "sliped the hook".  vin

Hi

thanks guys yes it does have auto spring i was hoping not to have to strip it .

Thanks for your time and help

can any one recommend a video to watch about this or some diagrams.

surely mark must have a video on this?

Just moved the auto wind on the back left and then right and it is winding in both directions. So can it still be the mainspring?

cheers

Hi Gary,
In my opinion it could still be the mainspring, yes. I’m sure I’ve seen a video that Mark made on the subject. If you’ve not done one before, do take extra care as mainsprings flying out of the barrel could cause injury so eye protection is important before starting. If you haven’t replaced the mainspring yet, it’s probably just as well to purchase a new one. Then you can just push it into the barrel generally shim coloured side up (for right hand wind).

Good luck,
Adam

Forgive  me if my terminology  is off..slipping could  only be but so many things.provided all your  gear teeth are good  and properly  engaged.it could  be your  mainspring.  Even  if it is broken  the watch could  run.I have seen it happen friction  and pressure  are often enough  to hold the spring in place up the a certain  amount  of tension..and then slipping occurs. You could  also have a cracked  barrel. Inspection is in order

Hi

I have just wound it fully using the auto bridge.(the bit that moves to auto wind it). I will check tomorrow and see if its still running. 

If not I will replace the spring. Are cousins own make good? There half the price of omega

Cheers

Cousins UK sells Generale Ressorts. They make springs for the entire Swiss industry since 1857.

Do you mean slipping as in you feel tension build then suddenly release which would point to the slipping spring which may be weakened or as in you feel like the teeth of the winding pinion are catching and disengaging?

This later would point to a meshing problem due to wear on winding pinion/crown wheel teeth or pivots or an assembly problem.

Hi

Wound it up last night by the auto winder and its still going and its the correct time. I have watched the clutch and crown gear and i cannot see a slipping movement. But i think it may be the crown gear so i will have to strip it and see.

If it is i will post pics tomorrow.

Thanks for all the advice and sugestions its much appreciated.

cheers

    • in general this shouldn't be any change. but in general questions like this it be nice to know the specifics of the watch in other words how was it performing before it was cased up and what is it doing now.
    • just as a reminder this watch is a Swatch group product. This will bring up a problem like spare parts and technical information. that I found some links to some information on when I talk about your watch and some of the technical and basically your watch is equivalent to 2834-2 for which I'm attaching the technical sheets. But equivalent does not mean exactly the same you want to do a search on the group for C07 as we discussed this watch before including the technical differences how it's supposed to be regulated and basically because it's watch group there is no parts availability. https://calibercorner.com/eta-caliber-c07-xxx/   https://www.chrono24.com/magazine/eta-movements-from-the-2824-2-to-the-powermatic-80-p_80840/ https://www.watchuseek.com/threads/h-10-movement-details.4636991/ eta CT_2834-2_FDE_481857_15.pdf
    • people be honest.... Swatch is evil for the watchmakers and repairers, BUT not everything in watches from Switzerland is from the Swatch-Group. As far as i know, Selitta got sacked by Swatch as a Movement-Assembler for them and they started to produce Movements in their own Name with slight Modifications. As far as i know, they sell Parts to the Market for their Movements. In most cases, if a ETA-Movement fails, it is a valid Option to replace it with a Selitta Movement, which i consider the Solution for this Mess with the Swatch-Group...... I have no Connection to anybody at Selitta, but being a Swiss-Guy, i still like to have Swiss-Made Watches, but not from the Swatch-Group.   ok ? regards, Ernst
    • Just one more greedy act by Swatch. They started a number of years ago here in the US..cutting off supplies to watchmakers that could build complications that many Swatch houses couldn't even touch. Old school masters who had gone through some of the most prestigious houses in the world. Otto Frei has some statements on their page about it. I tell all my customers to avoid new Swiss watches like the plague,..unless they just want an older one in their collection that still has some parts out on the market, or they have really deep pockets and don't mind waiting months and paying through the nose to get it back. Plenty of others to choose from..IE Seiko,..or other non-swiss brands Even a number of Chinese brands are catching up with the Swiss,..and I think that in time, their actions will be their downfall
    • Yes. If that's not what you are experiencing...start looking for something rubbing. A 1st guess is that one of the hands is rubbing against the hole in the center of the dial. Especially if you now have lower amplitude in face up/ face down positions.
