Manufactured in the 1940s, this is a Rolex Oyster Bubble Back unisex model, Type-AR, featuring a silver Roman numeral dial.
The silver dial, with mirror-printed “exploding” Roman numeral indexes paired with baton hands — a design also seen in NA-size Bubble Backs — has aged beautifully into a two-tone hue over time.
Though compact at 29mm, the watch retains the solid heft characteristic of Bubble Backs equipped with automatic movements. Combined with the unique proportions of the AR-type Bubble Back and the gracefully aged silver dial, it exudes a refined, condensed aesthetic that makes it a truly exceptional piece.
