Use of Lubeta V105 on Omega

I’m hoping this isn’t sounding a vexatious question, but is there an Omega tech sheet that covers the correct method for applying lubeta v105 to reverser wheels.

My understanding is that part is placed on watch paper, and a drop of lubeta v105 applied. After a minute the excess is removed with a puffer and then allowed to dry (for how long, or whether warm air is required, I’m not sure?).

Hoping someone can please guide me on the brand approved methodology.

Thank you in advance

Kind regards, Darren

That is not Omega's procedure. This is specifically covered under Omega Work Instruction 40, where it says this:

The first thing is that the wheel must be replaced, and not used again. Then the new wheel must be cleaned.

The wheel must be completely submerged in the V105, for at least 30 seconds.

The wheel is removed from the V105, and a hand blower is used to remove the excess solution.

The wheel is left to dry for 15 minutes on a surface that will not be affected by the solvent.

To test the reversing wheel, the watch is assembled, laid dial down, and then one side of the watch is elevated so that the movement is at a 30 degree angle. The crown is used to wind the watch, and if the rotor does not helicopter, the reversing wheels pass.

A couple of things I do that are not specified in the instructions...

I place it under a cover while it is drying.

Before I install the wheels, I hold the wheel by the pivot and use a blower on the wheels to make sure they turn freely.

Hope this helps.

fantastic! Thank you for clarifying and for your help once again.

I shall not be replacing the reverser on this occasion, but instead cleaning and treating with lubeta v105 as per the process you outlined above. If the auto winder proves to be problematic then I’ll take off the auto bridge and replace the reverser.

Do you think that V105 will be effective on oscillating weight centre bearing race, or do you prefer a very small quantity of 9010 as on the eta and omega sheet? Kind regards, Darren

Omega used to permit the reuse of the reversing wheels, but since you cannot see whatever wear might be inside, they now require them to be replaced at every service. I suppose if this is your own personal watch, you can decide to service it how you like. However if this is a watch you are servicing for a customer, I would very much recommend replacing the wheel.

One thing I always keep in mind when I am performing a service, is that I'm not just looking for proper performance and function now, but doing what is required to ensure that for 5 or more years into the future.

The proper solution for the bearing is V106 - I would not use V105 for this application.

Personally, I use 9010 on the bearings.

Make sure to perform the damping test to ensure that the bearing is in good condition...

Damping test? Is that giving the rotor a big swing and see how long it still wighles?

Yes, that's it.

Thanks for this Al, very helpful as always.

Which oil does Omega recommend for the rotor axle pivot? I have been using 9020.
