The 2777-2 RM contains a caliber 283 goose neck regulated movement that was only used in this very very limited reference. It is so rare that Omega did not know of its existence. Only through years of detective effort by

https://omegaforums.net/threads/a-g...rototype-black-dial-pristine-condition.47137/ did Omega finally locate the 2777-2 and 283 Goose Neck in the Omega archives.
As far as a restoration, the movement is not the issue. For certain, Omega Service should not be allowed to touch the watch as they will completely ruin it. Other vintage WM can service it with donor parts from a normal 283. The major hurdle is the dial. It is IMPOSSIBLE to find a replacement RM 2777-2 dial and this OP watch will never be a complete 2777-2, unfortunately. To me, the best alternative is using a 2777-1 RAF as a donor, approx $3,000 for a fat arrow version. A 2777-1 is the best place to find a workable antimagnetic dial to refinish, hands and movement parts.
