Reference 2021 is one of Rolex’s earliest chronograph models, first launched in the 1920s, featuring a hinged caseback and an olive-shaped chronograph pusher. Its most impressive feature, however is its lovely, multi-scale enamel dial, featuring a telemeter scale printed on the periphery of the dial and a snail-shaped tachymeter scale printer on the dial’s center.

Even though this model dates from the 1930s, it comes in a surprisingly large case making it look contemporary - perfect for modern tastes. Its enamel dial is in absolutely fantastic condition with black printing for its time telling and chronograph indications and bold, red printing for the telemeter and tachymeter scales. The combination creates a wonderful contrast against the blued hands, showcasing Rolex’s design mastery even in these early days.

Considering the non-waterproof case - Rolex started using the Oyster cases subsequently in the 1930s - the present timepiece is in exceptional condition, making it an extraordinary find for a wristwatch that is approximately 80 years old.
