Another attractive watch. Couple of questions to start; Is watch Yellow or Rose gold? Based on photos, it could be either/or.
Can you confirm date stamp is a circle? The case serial number would indicate a date of 1948.
If case is yellow and movement date is indeed 1944, watch presents itself as a
1948 Navigator with a correct caliber movement replacement from an earlier watch.
1948 Bulova Navigator, nice watch
