This 30.5mm boys-size Rolex Oyster Scientific stainless steel watch dates to 1941. The case gleams! The dial was expertly refinished with complicated outer seconds register and lume, Arabic numerals, and markers. We used two artisans to refinish these dials, one for the lume and another for the dial print. The original blued steel pencil hands and red sweep seconds complete the vintage look. This watch retains the original Oyster-patented winding crown. The stainless steel case glistens! Keep in mind, these vintage military watches were smaller in size.
