The 310.32.42.50.01.002 didn't arrive alone. Omega unveiled it in January 2021 alongside its Hesalite sibling, the 310.30, closing the book on the Cal. 1861-era references 145.022 and 311.30.42.30.01.005. The difference comes down to the crystal: sapphire on both sides instead of Hesalite, plus a display caseback with the Seahorse engraving instead of a solid one. Collectors already have a name for it — Sapphire Sandwich, or SSS Speedy for short.
## The DON Dot Makes a Comeback
The dial is where this reference really shows its hand. The tachymeter scale brings back the DON dot above the 90, a detail from the early Moonwatch years that Omega deliberately revived here. Below it sits a step dial with three-dimensional layering, catching light in a way no flat dial from the previous series ever did. The Omega logo is applied, not printed — a feature reserved exclusively for the Sapphire Sandwich line.
## Cal. 3861 Under the Hood
Inside beats the Cal. 3861, with a silicon balance spring and hacking seconds, Master Chronometer-certified. The display caseback lets you watch the movement in action, an option the Hesalite version simply doesn't offer.
## 2024 Brought the White Sibling
Three years after launch, Omega expanded the lineup with the 310.32.42.50.04.002, featuring a white lacquered dial and a calfskin strap. The black 310.32.42.50.01.002 itself hasn't changed a bit — it's remained a steady fixture in the collection since 2021, now also known among collectors as the Master Chronometer Moonwatch Leather.
Brand profile: Omega
Omega is the second most counterfeited Swiss watch brand. The Speedmaster and Seamaster are especially targeted. Pay close attention to movement details (Co-Axial) and dial textures.
- Speedmaster: The chronograph reset hand must snap back precisely to 12 o'clock — fakes stop 1–3 seconds off or wobble
- Speedmaster (Hesalite): The Omega logo is micro-laser-etched on the UNDERSIDE of the Hesalite crystal — only visible at a specific angle and in the right light — fakes omit it or place it incorrectly
- Seamaster: The wave-pattern dial must be ENGRAVED (tactile relief) — printed/flat wave lines = fake
- DON (Dot Over Ninety): small dot ABOVE the '90' on the Speedmaster tachymeter bezel — position/size often wrong on fakes
Serial number format: Omega serial number: 8-digit number on the caseback or between the lugs (on older models). Since ~2018 engraved on the caseback at 6 o'clock. Format: purely numeric. Verifiable on the Omega website with an extract from the archive.
