Omega Speedmaster Professional MARK II Ref. 145.014

Partially verified

This Omega Speedmaster Professional MARK II, reference 145.014, is a manual-wind stainless steel chronograph dating to 1973. It features a barrel-shaped case with brushed surfaces and polished chamfers, housing the Omega caliber 861 movement. The watch is distinguished by a matte grey "racing" dial featuring red and white checkering on its periphery and a mineral glass crystal that protects the internal tachymeter scale. It is fitted with an Omega 1171/173 stainless steel bracelet. The watch is identified by the vendor as coming from the collection of Magnus Walker. The current condition reflects past polishing of the case, and the watch retains its original crown, pushers, and tritium hands, with reported aging and light paint loss to the chronograph registers. It is presented as a functional vintage timepiece.

Object description

Case and Dial

The watch is housed in a barrel-shaped stainless steel case characterized by a brushed finish on the top and sides, complemented by polished chamfers. The timing scale is positioned beneath the mineral glass crystal, intended to protect it from external abrasion. The watch features an original Omega-signed crown and standard pump-style chronograph pushers.

The dial is matte grey, featuring a "racing" aesthetic with red and white checkering located on the outer edge. The hands and hour markers incorporate tritium luminous material. According to the provided description, the hands have developed a dark grey patina, and the dial shows tonal spots from age. There is reported minor paint chipping on the sub-register hands and the central chronograph hand.

Evidence for this section
  • “The barrel-shaped case appears to have been polished in the past, showing honest signs of use while still displaying the original bevels and dimensions throughout.”
  • “The classic timing scale that the Speedmaster is known for is also different; it is under the mineral glass crystal and not located on the outside of the crystal as an external bezel”
  • “The matte grey "exotic" racing dial is in wonderful vintage condition, showing some tonal spots from age but no notable damage.”

Movement and Function

The timepiece is powered by the Omega caliber 861, a manual-wind movement. This movement was used in various Speedmaster references, including the standard Professional "Moonwatch" of the period.

The auction description reports that the movement has been recently serviced and is currently maintaining time as expected.

Evidence for this section
  • “This watch contains Omega’s original caliber 861 movement and was in production from 1968 and lasted until 1996”
  • “The watch was recently serviced and is keeping time perfectly, backed by a 1-year warranty on accurate timekeeping.”

Provenance and Condition

The source indicates that this watch was previously held in the personal collection of Magnus Walker.

The case back retains original factory engravings, though these are described as largely faded. The watch comes with an Omega 1171/173 bracelet, which retains 20 links and shows signs of light stretch. The mineral crystal has a noted small chip at the 12 o'clock position.

Evidence for this section
  • “Fresh from the personal collection of style icon, automobile enthusiast, and Urban Outlaw himself, Magnus Walker, comes a 1973 Omega Speedmaster Professional MARK II in fantastic condition.”
  • “The original factory engravings on the case back have faded mostly from view by now but are still visible in the right light.”
  • “The mineral glass crystal is in good condition, showing no notable signs of wear except for a small chip at 12 o'clock.”

Open research questions

  • What is the specific production date range for serial number 32XXXXXX?
  • Does the bracelet end-link configuration 173 correspond correctly to the lug dimensions of the 145.014 reference?
