This is a 1935 Omega with a dual-name dial (sold by Birks jewelry store in Canada) is an interesting tonneau-shaped case marked “Kalonium,” which was an early name used to describe stainless steel. This dial with blued steel hands is completely original. The kalonium case measure 23x39mm. The manual winding Omega movement was just cleaned and is accurately keeping time. These early Omega watches are becoming harder to find in original condition.
