Tool to remove pusher nuts omega case 178.0504

[Cmmb8519]

Hi everyone 

Looking for advise on where to get a tool to remove the nuts of the screwed-on pushers of the omega seamaster professional case 178.0504. 

It seems to be a spline with 23 teeth, with 6mm diameter. 

Could not find this wide (6mm) for my horotec tool. 

Any suggestion on best tool to remove these? 

Thanks very much

They wouldn't happen to have an internal spline too? Reason for asking is that CousinsUK sells these Tube-keys specific for Omega Seamaster, be it for a different case-number (scroll to the bottom of the page):

You may have to warm up the case as those tubes may have been placed with some type of Loctite.

As last resort, you could try a pin-vice.
