Rolex Oyster Perpetual Date

Rolex Oyster Perpetual Date Ref. 1500

Grey Sigma Dial | 34 mm | ca. 1970s

A perfect blend of subtlety and style. This Rolex Oyster Perpetual Date Ref. 1500 from the 1970s is fitted with a rare grey sunburst Sigma dial, distinguished by warm tones and applied gold hour markers, with the discreet σ (Sigma) symbols at 6 o’clock, indicating the use of gold in the dial furniture.

These Sigma dials were part of a short-lived initiative by the Swiss watch industry in the early 1970s, launched to emphasize traditional craftsmanship and precious materials during the rise of quartz technology.

Housed in a 34 mm stainless steel Oyster case and fitted with its original riveted Oyster bracelet, this watch wears slim, solid, and comfortably modern, a timeless everyday companion with character and quiet sophistication.

The bracelet features the early “APRIOR” clasp, a desirable vintage detail prized by collectors for its construction quality, rarity, and period-correct charm.

Understated. Special. Built to wear.

And yes, 34 mm wears like a dream.
