Omega 8507

The rotor blocks access to one of the fixing screws. Any advice on how to get the rotor off the movement please.

Hi,
It's the seamaster 007 co axel.
The spiral rotor arm obstructs one screw there seems no way of removing it!

Screw obstructed.

You just turn the rotor so the screws can be accessed individually. Omega's instructions for this literally state that...

"Disassemble and assemble the 3 screws of the automatic module (position the oscillating weight to allow access to the screws)."

Thanks for that however, one screw is obstructed in whatever position the rotor is placed!

If the screw you are trying to remove cannot be removed by turning the rotor, it is likely not a screw for removing the automatic winding...

Hello everyone,
My name is Juliano Pinto Santos, and I am an experienced professional watchmaker with many years of experience in watch servicing and repairs. I work at Dynamis Watch Service.
I would like to share a solution I found while servicing the Omega calibre 8507 James Bond, which features the special spiral-shaped rotor.

The problem:
Unlike the standard Omega 8500 rotor, the special James Bond rotor makes it extremely difficult to access the third screw securing the automatic winding module.

Two screws are easily accessible, but the third remains almost completely hidden beneath the rotor, close to the gold centre marked "JAMES BOND".
OMEGA CALIBRE 8507 JAMES BOND - SOLUTION FOR REMOVING THE HIDDEN THIRD SCREW

Hello everyone,

My name is Juliano Pinto Santos, and I am an experienced professional watchmaker with many years of experience in watch servicing and repairs. I work at Dynamis Watch Service.

I would like to share a solution I found while servicing the Omega calibre 8507 James Bond, which features the special spiral-shaped rotor.

The problem:

Unlike the standard Omega 8500 rotor, the special James Bond rotor makes it extremely difficult to access the third screw securing the automatic winding module.

Two screws are easily accessible, but the third remains almost completely hidden beneath the rotor, close to the gold centre marked "JAMES BOND".

My solution:

1. First, I removed the two accessible screws securing the automatic winding module.
2. I carefully rotated the rotor until a very small portion of the third screw head became visible.
3. Because the available space was extremely limited, I used a fine, yellow-handled watchmaker's screwdriver with a slightly thinner blade.
4. I carefully positioned the screwdriver at a slight angle, allowing the tip to engage the exposed portion of the screw slot.
5. With gentle, controlled movements, I gradually loosened the screw and continued turning it until it was completely removed.
6. Once all three screws were removed, I was able to remove the automatic winding module and rotor assembly.

Important: There was no need to remove the gold JAMES BOND centre piece or dismantle the rotor beforehand.

This procedure requires patience and precision, as working with the screwdriver at an angle carries a risk of slipping and damaging the screw or rotor.

I have attached several photographs showing the movement, the partially hidden screw, the removed rotor and the automatic winding module.

I hope this information will help other watchmakers who encounter the same problem with this particular Omega calibre.

This is a practical workshop solution based on my own experience, not an official Omega service procedure.
