Replica Rolex Datejust 36 Black Sigma Dial Vintage Steel Watches 1601

The black Sigma dial of the Rolex Datejust replica is a notable feature. Sigma dials were used by Rolex during the 1970s and early 1980s and were marked with the Sigma symbol at the bottom of the dial. These dials were created using special techniques and were associated with watches featuring solid gold hour markers and hands. The Sigma symbol indicated that the markers and hands were made of gold. The movement inside the watch can vary depending on the specific reference and production year. Vintage Datejust watches were typically equipped with Rolex’s self-winding mechanical movements, known for their accuracy and reliability.
