Rolex Air-King

A plain Oyster Perpetual without a date, honouring the British pilots of the war.
In the 1940s Rolex gave several models aviation names as a tribute to the pilots of the Royal Air Force. The Air-King remained and in 2016 got a new dial with large minute numerals.
Materials: Stainless steel; self-winding movement
Manufacture: Made in Geneva; one of Rolex's simplest models.
The name Air-King on the dial.
The smooth bezel and the absence of a date.
