18K Rolex Datejust Diamond Dial and Sapphire Bezel President Band Wristwatch

Item Details

Rolex wristwatches are among the highest quality timepieces available, both today and throughout the past century. Founded in 1905 in London and later moved to Switzerland, the company is known for its Oyster Perpetual, Professional, and Cellini lines. Rolex set a new standard for accuracy and has generated many patents throughout its history. Given their dependability and durability, Rolex watches are worn by aviators far above the earth and divers deep beneath the sea–not to mention everyone else in between.
