Reference 6611 is considered as one of the rarest Day-Date models in Rolex’s history. The present example, a 6611B, is especially rare, not only because it is in white gold, but it also features an updated movement compared with the 6611, and is exceedingly rare without diamond hour markers. Introduced in 1957, it is fitted with Rolex’s automatic calibre 1055 B that incorporated a free-sprung balance wheel with a micro-stella fine adjustment for improved accuracy, while at the same time measured 0.1mm thinner than its predecessor.

The “pie-pan” dial has a very attractive pale champagne-colored patina, with the outer minute track positioned downward at a slight angle. What makes this reference particularly special is that it is the first Rolex to have the text “Superlative Chronometer Officially Certified” included on the dial at 6 o’clock.

This example is fitted with an attractive reeded bezel, and without luminous dots at the hour markers like many other variations of the Rolex Day-Date. Its leaf-shaped hands are similarly non-luminous, with black enamel used in their centres. The versatile elegance of this understated piece makes it easy to wear in casual or formal settings, making it a fantastic watch for the practical collector.
