OMEGA SPEEDMASTER PROFESSIONAL REF. 310.30.42.50.01.001 (HESALITE) C.2021-2024: IDENTIFICATION

This is a contemporary Omega Speedmaster Moonwatch Professional featuring the Calibre 3861 manual-wind Co-Axial Master Chronometer movement. The dial is the 'stepped' matte black variant with printed Omega logo and luminova markers, protected by a hesalite (acrylic) crystal. Note the five-link-across brushed stainless steel bracelet with a 20mm to 15mm taper and the distinctive 'dot over ninety' (DON) tachymeter bezel. This specific configuration, with its fully brushed bracelet links and printed logo, identifies it as the hesalite model rather than the sapphire 'sandwich' version.

PRODUCTION & REFERENCE HISTORY

The Omega Speedmaster was first introduced in 1957 as Ref. CK2915, but this 2021 update (Ref. 310.30.42.50.01.001) pays homage to the Ref. 145.022-69 used during the Apollo missions. The reintroduction of the 'step dial' and 'DON' bezel 50 years after their original production signifies Omega's ...
The Omega Speedmaster was first introduced in 1957 as Ref. CK2915, but this 2021 update (Ref. 310.30.42.50.01.001) pays homage to the Ref. 145.022-69 used during the Apollo missions. The reintroduction of the 'step dial' and 'DON' bezel 50 years after their original production signifies Omega's shift toward vintage-accurate aesthetics in their modern core collection. The Calibre 3861 movement inside is the first major mechanical upgrade to the Moonwatch in over 20 years, introducing METAS certification and high magnetism resistance (15,000 gauss) as recorded by Omega in 2021.

COLLECTOR NOTES

1

The 2021 bracelet update features a taper from 20mm at the lugs to 15mm at the clasp, making it significantly narrower than the 18mm taper of the previous Calibre 1861 models.

WATCHMAKER'S ASSESSMENT

Vintage Watchmaker & Horology Specialist

Horologist

Identification is high due to the presence of multiple reference-specific traits (step dial, all-brushed bracelet, printed logo) that align perfectly with the modern 3861 hesalite model specifications.

KEY EVIDENCE

  • 1Correct teardrop counterweight on the chronograph seconds hand for the 3861 reference
  • 2Step dial present with clearly defined indentation at the minute track
  • 3Printed (not applied) Omega logo indicates the hesalite (Ref .001) variant
  • 4All-brushed bracelet links correctly correspond to the hesalite model specifications
  • 5Dot-Over-Ninety (DON) bezel alignment is factory-correct

WHAT WOULD IMPROVE CERTAINTY

  • →Check the clasp for the micro-adjustment button introduced in 2022-2023 batches
  • →Verify the laser-etched Omega symbol in the center of the hesalite crystal under 10x magnification
  • →Request view of the Calibre 3861 movement to confirm the serial number matches the lug engraving
