. . . but I've little experience with Omegas prior to the cal 30. Possibly a national production item with movement and dial sourced from Switzerland, but cased elsewhere?
I wouldn't be concerned about the feasibility restoring it, but there doesn't seem to be quite as much interest in this earlier period of Omega than the post-cal 30 era. It would be worthwhile to check parts suppliers to see if movement parts are still readily available.
Best,
