Rolex Datejust Reference 6605

Partially verified

This Rolex Datejust reference 6605 is a 36mm stainless steel self-winding wristwatch featuring an 18k white gold fluted bezel. Introduced in 1956, this reference utilizes the calibre 1065 movement. The timepiece is characterized by a cream-coloured, pie-pan style dial with applied dagger-shaped hour markers and an applied Rolex coronet. The dial includes a "Swiss" only signature and is paired with dauphine hands. The date display incorporates a roulette date disc, alternating between red and black numerals, positioned beneath a Cyclops magnifying lens on the crystal. The watch is currently presented on a Bulang and Sons leather strap. The auction description reports that the movement has been fully serviced by their watchmaker. This example bears the serial number 415xxx, which the source dates to 1958, and features the "Superlative Chronometer Officially Certified" designation on the dial.

Object description

Case and Bezel

The watch is housed in a 36mm stainless steel Oyster case, which the vendor describes as remaining in a preserved condition. The case is complemented by a fluted bezel crafted from 18k white gold.

The design of the reference 6605 was intended to maintain the robustness associated with the Oyster case while adopting a slimmer profile than preceding "Bubbleback" models. A Cyclops magnifying lens is integrated into the crystal above the date aperture.

Evidence for this section
  • “36mm stainless steel Oyster case remains in lovely condition and is fitted with the elegant finely fluted 18k white gold bezel.”
  • “It introduced the slimmer in-house calibre 1065, allowing Rolex to move away from the thicker "Bubbleback" profile while retaining the robustness for which the Oyster case had become famous.”

Dial and Hands

The dial is described as a cream-coloured, pie-pan style configuration. It features applied elements, including dagger-shaped hour markers and a Rolex coronet. The dial displays the designation "Superlative Chronometer Officially Certified" and contains the "Swiss" signature at the six o'clock position.

The time is indicated by dauphine hands, which are positioned against the aged cream dial surface. The date display utilizes a roulette disc, which features alternating black and red numerals, visible through the date aperture.

Evidence for this section
  • “The beautifully aged cream-coloured pie-pan dial features an applied Rolex coronet, applied dagger hour markers, black printed text, the desirable "Swiss" designation at six o'clock, and elegant dauphine hands.”
  • “Adding another charming detail is the original roulette date disc, alternating red and black numerals”

Movement and Chronometry

The watch is powered by the in-house Rolex calibre 1065. This movement was specifically utilized in the reference 6605, marking a transition in the construction of Datejust models during the late 1950s.

The dial bears the "Superlative Chronometer Officially Certified" inscription, identifying the watch as a chronometer-rated timepiece.

Evidence for this section
  • “It introduced the slimmer in-house calibre 1065”
  • “The 6605 also ranks among the earliest Datejust references to feature the now-familiar "Superlative Chronometer Officially Certified" designation on the dial”

Open research questions

  • What is the specific production month for serial number 415xxx?
  • Are there any documented variations of the 18k white gold bezel fluting for this specific reference 6605?
