Which Omega Speedmaster to buy: Moonwatch, 38mm, '57 or Racing? (2026)

For most people, the best Omega Speedmaster is the Moonwatch Professional: 42mm, hand-wound, with Omega's Master Chronometer calibre 3861. If you'd rather not wind a watch, the automatic Speedmaster 38. For the slimmest Speedmaster, the '57.

Every watch here is sold new by Goldsmiths, a UK authorised Omega retailer. Prices are Goldsmiths' own on the date shown.

How we chose

We went through the Speedmasters Goldsmiths has in stock, more than 60 of them, and read Omega's own product pages for each family: the calibre, whether it winds itself, the crystal, the thickness and the lug-to-lug (the length from tip to tip, which decides how big a watch looks on your wrist). We earn a commission if you buy through our links, which never changes the price you pay.

Every Speedmaster compared

Measurements, winding and crystals are Omega's own, from its product pages (Omega doesn't list a thickness for the Chronoscope we checked). Prices are Goldsmiths' for the version shown.

Two things stand out. Most of these Speedmasters are hand-wound, including the Moonwatch: you turn the crown every day or two. If you want one that winds itself, choose the 38, the Pilot or the Racing. And the 42mm Moonwatch wears smaller than its size suggests: its 47.5mm lug-to-lug is shorter than the '57's, which is only 40.5mm across.

The best Omega Speedmaster overall: the Moonwatch

This is the Speedmaster. Goldsmiths' description says the Moonwatch was part of all six Moon landings, and the case back is engraved "the first watch worn on the moon". Today's version has Omega's calibre 3861, hand-wound, certified as a Master Chronometer, with a 50-hour power reserve, according to Omega. It's water resistant to 50 metres, so fine for everyday wear but not for diving.

Hesalite or sapphire?

The Moonwatch is sold with two crystals. Hesalite is a type of acrylic: it scratches more easily than sapphire, but light scratches can be polished out, and it's the less expensive version. Sapphire is far more scratch-resistant. Omega gives the sapphire version as 13.18mm thick, against 13.54mm for the Hesalite. When we checked, Goldsmiths' sapphire Moonwatch cost £7,500, against £6,600 for the Hesalite. If you'll wear it every day and don't want to worry about scratches, choose sapphire.

On a strap, or with a white dial. The Hesalite Moonwatch also comes on a nylon strap, for less. The white-dial Moonwatch has a sapphire crystal and comes on a steel bracelet or a rubber strap.

The best automatic Speedmaster: Speedmaster 38

The Speedmaster for people who don't want to wind a watch. Omega lists the self-winding calibre 3330 with a 52-hour power reserve and 100 metres of water resistance, twice the Moonwatch's. The case is 38mm with a 44.9mm lug-to-lug, so it suits smaller wrists, though at 14.7mm it's thicker than the Moonwatch. It's also one of the least expensive Speedmasters at Goldsmiths.

The slimmest Speedmaster: the '57

Goldsmiths' description says the Speedmaster '57 collection was first introduced in 2013 and has returned slimmer, with a vintage look and a date window at six o'clock. Omega gives it 12.99mm thick, the slimmest Speedmaster we measured, with the hand-wound calibre 9906 and a 60-hour power reserve, ten hours more than the Moonwatch. It's 40.5mm across but has a long 49.64mm lug-to-lug, so it wears longer than its diameter suggests.

The '57 comes on a steel bracelet or a strap, in black, blue and green.

The best Speedmaster for smaller wrists: First OMEGA in Space

Goldsmiths' description says it's a tribute to the Speedmaster CK 2998 that astronaut Walter Schirra wore on the Sigma 7 mission in 1962, the first OMEGA worn in space. Omega gives it 39.7mm across (Goldsmiths lists it as 40mm and calls it the Anniversary Series), 13.38mm thick and 48mm lug-to-lug, with the same hand-wound calibre 3861 as the Moonwatch and a sapphire crystal shaped like Hesalite.

Speedmaster or something else?
