Item No. VR - 17

Tudors: "Manufactured under strict Rolex supervision and bear the Rolex label of guarantee." - Quote from a vintage advertisement in Britain's Horological Journal

Many collectors are not especially acquainted with watches from Rolex's Tudor brand, creations which have become increasingly more collectible. Watches in the Tudor line, apart from the fact that they utilize ebauche movements, are similar to those of Rolex in design and construction.

When Rolex launched the Tudor brand in 1945, they strongly intended that the public perception of its quality had to equal that of Rolex. To achieve this lofty aim, until the mid-1990's, Tudor watches featured Rolex cases and crowns, and, until 1971, Rolex bracelets.

One such watch from the Tudor line was the Prince Oysterdate. It was patterned after the Rolex Datejust, the company's most famous model. In its early days the Tudor Oysterdate earned a name for itself as essentially a more affordable version of its sister watch. Possessing the same features and conception, it was cheaper and thinner than its Rolex sibling.

Today's offering showcases this Tudor Prince Oysterdate. It is part of a large collection that we are now selling for a pediatrician.

The Tudor dial has been previously refinished in a so-called "California" Rolex style with mixed Arabic and Roman numerals. It originally would have been printed "Tudor Prince Oysterdate."

Its stainless steel Rolex Oyster case is in excellent condition. And its automatic Tudor movement with quick-setting date movement winds smoothly.

Included with the purchase is a 90-day international warranty on the movement and its function and a custom printed Connoisseur of Time Certificate of Authenticity.
