Balance Complete for Omega 30t2pc


Hi guys. I'm looking for a complete balance assembly for an Omega 30t2pc. But I'm not sure of the part number.

Cousins list it as "Balance Complete ( 1327 ), Omega 260". But they list the same part for the entire Omega 30t series. Even though I know the balance staffs are different sizes in this series depending on whether there is an inca shock (I found this out from balancestaffs.com). The t2pc has an inca shock so I don't think the one Cousins list will fit properly.

Does anyone have any knowledge of this movement? Or some documentation that might help? Thanks in advance :)

Hej Igen, 
Yes there are two different stems on cousine and it is as you say with or without shock. Below I compiled a small list one can use.

OMEGA 265-266

OMEGA 26.5
OMEGA 26.5T1
OMEGA 26.5T2
OMEGA 26.5T3

Okay. I'm slowly getting my head around this. The 30t2pc is now called the 260. So according to this PDF Cousins are indeed listing the correct part. The 260 / 1327.

What's confusing me is that they list the same part for the 30t2 with no shock. Even though that one requires a different size balance staff.

And also Balancestaffs.com lists the ronda 1856 as being compatible with the shock and non-shock. Even though the staffs are a different size. :startle:

If you look at cousine you will see the balance complete for your movement 30T2PC is the same as for the Omega 260, "Balance Complete ( 1327 ), Omega 260" which is the one they use for the whole range of movements using the same balance cock with incablock shock.

There is an 30T2RG too but this one has no shock and therefor use one other balancestaff (RONDASTAFFS1856) and the balance cock here originated from the caliber 26.5.

The Omega 260 balance complete is marked obselete on cousine so you have to look at the option to replace the balance staff with the one called "OME2601321" at cousine..

But if you would search the bay sometimes you might find one looking for the other calibers using the same staff.

I missed your post with the balancestaffs.com
30T2RG = OME26.5 BS4132 (RONDASTAFFS1856) (A=305) This also has an early inca version BS4133 (RONDASTAFFS4187) (A=305)
30T2PC = OME260  BS4149 (RONDASTAFFS3276) (A=329) and now I see what you mean, here they say you could use the slightly longer version too BS4148 (RONDASTAFFS1858) (A=332) which I'm not so sure of, even if the staff lenght isn't that far off it might affect the movement of the balance wheel since the pressure from the inca block springs would be slightly higher all time and one might not have any endshake at all. I would go with the original lenght of these.

    • I got this little beauty  at a swap meet on Sunday.  I changed the battery and still nothing.  I know nothing about quartz. Is there a trick I kneed to know?  Is it worth taking down to be repaired?  Should I look for an ETA movement to put inside?  It does have the gold matching band in good condition.

    • Thank you AndyHull and JerseyMo for responding with really helpful instructions!  You guys rock!  i have to get some rodic to help hold these two little mini-monsters in place. I was trying to use a small bit of sticky-tack but it didn't hold well enough.  I would get the screw into position but it would fall over when the screwdriver touched the screw.   For the 24 movement that still has the broken screw end in it, I will try to get that out after I get the lever and screw installed in my working 24.  And yes, I will install the crown/stem AFTER I have the lever and screw in place on the plate. Again, thanks for your help- i really appreciate it!!!  Will let you know when I get things back together.
