The 145.0022 is the standardised successor to the 145.022, arriving in the early 1980s to bring consistent caseback numbering to a design that had already been to the Moon. The asymmetric twisted-lug case — those protective ears around the crown and pushers — dates to the original Speedmaster's brief and has never been architecturally revised, which is why this watch reads as something drawn for a specific purpose rather than something styled to look as though it was. The calibre 861, derived from the Lemania 1873, is the movement that carried the Speedmaster through the Apollo training programme and into the Space Shuttle era. It is cam-controlled rather than column-wheel, manually wound, and built to a standard of environmental resilience that most chronograph movements were never asked to meet. The 48-hour power reserve is modest, but the movement's reputation was never built on figures — it was built on what it did when everything else was failing. On the wrist, the asymmetric case makes 42mm read closer to 40, and at 48mm lug to lug it sits without overhang on most wrists. The bracelet adjusts through friction pins in the links and a row of micro-adjustment positions in the clasp cover — fiddly by modern standards, but correct for the period, and worth knowing before you sit down to size it.

Learn more about Omega
Louis Brandt began assembling pocket watches in La Chaux-de-Fonds in 1848. His sons moved production to Biel in 1880 and, in 1894, released a calibre whose parts were fully interchangeable and which could be serviced by any watchmaker with standard tools. They named it Omega. The movement was successful enough that the company took its name.
Omega's history is bound up with measurement in public. It became official timekeeper of the Olympic Games in 1932 and has held the role for most Games since, which drove genuine engineering: photo-finish cameras, touchpads in swimming pools, and the timing systems that made hundredths of a second meaningful.
NASA qualified the Speedmaster for manned spaceflight in 1965 after testing chronographs from several manufacturers to destruction, and it was on Buzz Aldrin's wrist on the lunar surface in 1969. The watch has never been substantially redesigned.
The Seamaster line dates to 1948 and covers everything from dress watches to saturation diving instruments. Omega's technical position strengthened considerably after 1999 with the adoption of George Daniels' co-axial escapement, the first genuinely new escapement to reach series production in two centuries, and more recently through Master Chronometer certification testing resistance to magnetic fields at 15,000 gauss.
The company has been part of the Swatch Group since its formation.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Showering yes, swimming no. 60m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Will the glass scratch?
Yes, but it polishes out. Acrylic marks easily and a scratch can be buffed away at home, which is why vintage-style watches still use it.
Does it need a battery?
No. It is hand-wound, so it needs winding every day or two but never a battery.
How long does it run for when it's not worn?
About 48 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
20mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 48mm, which suits wrists from roughly 16.5cm (6½ inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's.
