Rolex Datejust 36 Reference 16014 Custom-Modified Wristwatch

Partially verified

This object is a custom-modified stainless steel automatic wristwatch based on a Rolex Datejust 36 case, reference 16014 with serial number 5495910. The timepiece represents a multi-era assembly fitted with an earlier Rolex calibre 1570 automatic movement and a downsized grey Sigma dial originally intended for a 34mm Rolex Oyster Perpetual Date model. Because of the smaller dial dimensions, the underlying mechanism edge is visible inside the 36mm case. The case and aftermarket Jubilee-style bracelet are pavé-set with round brilliant-cut diamonds, complemented by an aftermarket diamond bezel, synthetic sapphire crystal, Twinlock crown, and date aperture at 3 o'clock.

Object description

Object Identity and Configuration

The object is described as a custom-modified Rolex Datejust 36, reference 16014, serial number 5495910. The source characterizes the timepiece as a 'custom multi-era assembly' or 'Frankenstein' build, stating that the components do not historically or mechanically belong to each other.

The case features a caseback interior numbered 16000 with two service marks. The exterior has been modified with an aftermarket diamond-set bezel, which the source notes is secured with adhesive, and an aftermarket stainless steel Jubilee-style bracelet finished with pavé-set diamonds.

Evidence for this section
  • “Case model 16014, serial number 5495910.”
  • “This timepiece represents a custom multi-era assembly ("Frankenstein" build); the mid-1970s Calibre 1570 movement, the 34mm Sigma dial, and the 1978-era 16014 case structure do not historically or mechanically belong to each other and have been adapted to fit.”
  • “Caseback interior is appropriately numbered 16000 and displays 2 service marks.”
  • “The aftermarket diamond bezel is securely glued down.”

Dial and Movement Assessment

The watch is powered by a Rolex Calibre 1570 movement, numbered D332306. It is fitted with an authentic grey 'Sigma' dial originally sized for a 34mm Rolex Oyster Perpetual Date model. Because the 34mm dial is housed in a 36mm case, the edge of the movement is visible.

Reported condition issues include aging of the dial and hands, a date disc that is mildly misaligned, and physical resistance or catching of the seconds hand during time setting. The movement is observed to wind, set, and run.

Evidence for this section
  • “Powered by a genuine, earlier-generation vintage Rolex Calibre 1570 26-jewel automatic movement, numbered D332306.”
  • “Features a custom-fitted, authentic vintage grey "Sigma" dial originally scaled for a 34mm Rolex Oyster Perpetual Date model.”
  • “Because this smaller 34mm dial has been custom-housed inside a larger 36mm case, the edge of the underlying mechanical assembly is visible around the perimeter.”
  • “The seconds hand exhibits physical resistance and catching during time setting, and the date disc display is mildly misaligned within the dial window”

Additional Components and Condition

The watch utilizes aftermarket components, specifically the synthetic sapphire crystal, diamond bezel, bracelet, and clasp. The clasp bears Rolex branding and is numbered 72200 with code CL5.

The overall condition is described as fair. The bracelet is missing one diamond, and an additional diamond is tilted and loose in its setting. The lugs are fully drilled.

Evidence for this section
  • “Crystal is aftermarket. Bracelet and clasp are aftermarket.”
  • “With a fold-over clasp bearing Rolex branding, numbered 72200 and stamped with code CL5.”
  • “Bracelet is missing 1 diamond, 1 additional diamond is tilted and loose in its setting.”

Open research questions

  • What is the provenance of the component parts identified as 'mid-1970s' and '1978-era'?
  • What is the significance of the two service marks displayed on the interior of the caseback?
