About Omega 42mm Watches
Omega's 42mm case size has a particularly storied history within the Speedmaster line, where the Professional Moonwatch has been produced at or near this diameter since its earliest NASA-qualified references in the 1960s, including the legendary Pre-Moon 145.022 series worn by Apollo astronauts. The modern Speedmaster Moonwatch Professional continues that heritage with a manually wound movement housed in a 42mm stainless steel case, featuring the iconic black dial with index or applied hour markers and a tachymeter bezel. The Seamaster Planet Ocean at 42mm represents Omega's professional dive watch expression in a case size that balances robust functionality with everyday wearability, offered here with a black bezel and Arabic index dial in stainless steel. Together these lines define what a serious sport watch at 42mm looks like across generations of Omega manufacture.
What to Look For
When shopping this 42mm collection, pay close attention to reference numbers because subtle differences between, for example, the 310.30.42.50.01.001 and the 310.32.42.50.01.001 reflect meaningful distinctions in bracelet or strap configuration, with the 310.32 series pairing the Moonwatch case with a NATO-style nylon fabric strap while the 310.30 series typically ships on a bracelet or leather strap. Condition designation matters equally: brand-new examples carry full manufacturer packaging and warranty documentation, while pre-owned references like the 2201.51.00 Planet Ocean or the vintage 145.022-69 Pre-Moon are priced to reflect honest wear and represent strong entry points for collectors. Dial originality, especially on the Pre-Moon 145.022, is a primary value driver and is assessed in Bizak and Co.'s authentication process before any piece is listed for sale.
Frequently Asked Questions
What is the difference between the Omega Speedmaster 310.30.42.50.01.001 and 310.32.42.50.01.001?
Both are current-generation Speedmaster Moonwatch Professional chronographs in 42mm stainless steel with black dials, but they differ in how they are presented on the wrist. The 310.30 reference is generally paired with a bracelet or leather strap, while the 310.32 reference comes fitted with a nylon fabric NATO-style strap, making it the more casual and lightweight wearing option.
Is the Omega Speedmaster Pre-Moon 145.022-69 a good buy for a collector?
The 145.022 is one of the most historically significant Speedmaster references, representing the final evolution of the case design that flew on the Apollo missions, and it is highly sought after by serious Omega collectors. When buying pre-owned, the key factors are dial originality, case sharpness, and whether the movement has been properly serviced, all of which Bizak and Co. evaluates before offering a piece for sale.
