Rolex Chronograph 3525

Rolex Chronograph Ref: 3525

The Mononlock or Bariletto (so called for its barel like small case) was one of the first waterproof chrographs Rolex made. At 80 + years old, this particular example has a restored dial (probably done in the UK under license by Daust back in the 1960s) while the case has probably never been polished, which its razor like sharpness varifies.
