Omega watches: the complete 2026 guide to every current model
Four collections, a Master Chronometer standard nobody else matches at the price, and a Seamaster range deep enough to confuse anyone. This is our map of the Omega catalogue — what each model is actually for, and where to read the reference-by-reference detail.
Written and maintained by The Watchology. Specifications reflect the 2026 catalogue; pricing lives in each model guide, dated, rather than in a figure here that would be stale within weeks.
Start here
- Never owned one? The Aqua Terra is the easiest Omega to live with — dressy enough for work, robust enough for everything else.
- Want the icon? The Speedmaster Moonwatch is the one with the history, and it is still hand-wound.
- Want a dive watch? Start with the Seamaster Diver 300M, then compare it against the Planet Ocean.
- Cross-shopping Rolex? Read Rolex vs Omega before you commit either way.
The Seamaster family
Omega’s dive collection, and the deepest part of the catalogue. Four distinct sub-families that people routinely mix up.
Seamaster — the overview
Start here if the Seamaster range itself is what is confusing you. It sets out how the sub-families differ before you go deeper.
Diver 300M
The Bond diver and the one most people mean by “Seamaster”: 42mm, wave dial, helium escape valve.
Planet Ocean
Bigger, more serious, more capable — the professional end of the dive range, with a 600m rating.
Aqua Terra
The everyday Omega. A dive-adjacent case with a teak-pattern dial that reads as dressy on a bracelet.
The Speedmaster family
The chronograph collection — and the only watch flight-qualified by NASA for extravehicular activity.
Moonwatch
The Professional. Hesalite or sapphire, hand-wound, and essentially unchanged in silhouette since the 1960s.
Dark Side of the Moon
The Moonwatch reimagined in black ceramic — larger, automatic, and a very different presence.
Chronoscope
A vintage-styled chronograph with the tachymeter, telemeter and pulsometer scales printed on the dial.
Speedmaster Mark II
The cushion-cased 1970s reinterpretation — the Speedmaster for people who do not want the obvious one.
The dress collections
Where Omega competes with the Datejust and the Cellini rather than with dive watches.
Constellation
The one with the griffe claws and the observatory back. Divisive design, genuinely excellent finishing.
De Ville
Omega’s classical dress line, including the Préstige and the Trésor.
Which Omega should you buy?
The honest short answer for the situations people actually write in about.
| If you want… | Look at | Why |
|---|---|---|
| One watch for everything | Aqua Terra | Dressy on a bracelet, tough enough not to baby. The most versatile watch Omega makes. |
| A dive watch | Diver 300M or Planet Ocean | The 300M is slimmer and more wearable; the Planet Ocean is the serious tool. |
| The historic one | Speedmaster Moonwatch | Nothing else carries the same story, and it is still a manual-wind chronograph. |
| Something dressy | Constellation or De Ville | The Constellation is bolder; the De Ville is the traditional choice. |
| Something understated | Railmaster | No date, no bezel, no shouting. Genuinely hard to find fault with. |
Omega compared with the alternatives
The comparisons worth reading before you commit.

| Diver head-to-head | Seamaster 300M vs Submariner | The single most-asked dive watch question. |
Omega questions we get asked most
For most first-time buyers the Aqua Terra makes the most sense — it is the most versatile watch in the range and works in almost every setting. If you want the icon rather than the all-rounder, buy the Speedmaster Moonwatch.
Both are Seamaster dive watches, but the Diver 300M is slimmer, lighter and easier to wear daily, while the Planet Ocean is a larger, more capable tool watch rated to 600m. See both guides for the reference-level detail.
Yes — the Professional Moonwatch remains a manual-wind chronograph, which is central to its character. The Dark Side of the Moon is the automatic, ceramic alternative if you would rather not wind a watch daily.
Omega is generally easier to buy at retail and discounts more readily on the secondary market, which usually means more watch for the money up front — but Rolex tends to hold value better. Our Rolex vs Omega comparison works through the trade-off properly.
