1960 Rolex Oyster Perpetual Date 1501 - Matte Black, Sigma Dial - With Box - Automatic Cal. 1570

There's something magnetic about a watch that whispers rather than shouts, and non-polished 1960 Rolex OP 1501 does exactly that.

What is a Sigma dial, and what makes it so special?

Look closely at the 6 o'clock position, and you'll spot two small Greek sigma symbols (σ) flanking the Swiss Made designation. The sigma symbols weren't just decorative flourishes—they were Rolex's way of indicating that the dial contained solid gold hour markers rather than simply gold-plated ones, making sigma dials relatively rare in the broader scope of Rolex production. Framing this stunning matte black dial is the engine-turned bezel, which makes it wear slightly bigger.

It's on the ref. 7835 19 folded oyster bracelet with the 357 endlinks. 13 links in total, 18.6CM maximum wrist size. It's truly difficult to come across a Rolex that's over 60 years old and still has its crystal. And once again - with the box. It's powered by the automatic cal. 1570 that holds time accurately, daily difference of +8 seconds/day. Happy to answer any questions and provide more pictures!
