The ’57 name points to the line’s heritage; it does not mean the modern watches are unchanged versions of the original.
What does the Speedmaster ’57 name mean?
Omega uses “Speedmaster ’57” for a modern line that draws on the design of the first Speedmaster, launched in 1957. The name connects the later watches to that heritage, but the historical CK 2915 and the modern ’57 generations are distinct models with different specifications.

Omega identifies the 1957 Speedmaster as the Broad Arrow, reference CK 2915, and places it among the brand’s professional-watch trilogy from that year. It is the historical original—not the 2013 watch. Omega’s official history of the 1957 Broad Arrow provides that context.
How the three generations differ
| Generation | Identification | Case and movement | Chronograph and other details |
|---|---|---|---|
| 1957 original | Broad Arrow, CK 2915 | Exact dimensions and movement are not stated on the cited Omega history page. | Omega identifies it as the original Speedmaster and part of the 1957 professional-watch trilogy. |
| 2013 generation | Speedmaster ’57, reference 331.10.42.51.01.001 | 41.5 mm; calibre 9300, according to Omega’s page for this specific reference. | 60-minute and 12-hour chronograph recorders share the subdial at 3 o’clock; small seconds is at 9 and date at 6. |
| Later generation | Speedmaster ’57 Master Chronometer collection | 40.5 mm stainless-steel collection. The cited collection page does not establish one movement specification for every reference. | Omega describes an eight-model collection with new colours and Master Chronometer status. |
The 1957 original: Broad Arrow CK 2915
The CK 2915 is the starting point for the Speedmaster’s history. Its Broad Arrow name refers to the distinctive broad-arrow hands, a styling cue that later ’57 watches revisit. Omega’s history page is the source for its identification as the first Speedmaster and its place in the 1957 trilogy.
#1 Best Overall
The available Omega source does not establish the original’s case dimensions or movement specifications, so they should not be inferred from modern ’57 models. Nor does a shared design cue make a modern watch an exact reproduction of the vintage CK 2915.
The 2013 Speedmaster ’57: 41.5 mm and calibre 9300
Omega says the Speedmaster ’57 was first introduced in 2013. Its product page documents reference 331.10.42.51.01.001 as a 41.5 mm watch powered by calibre 9300. Those details apply to that cited reference, not automatically to every watch carrying the ’57 name. Omega’s product page for reference 331.10.42.51.01.001.
How its chronograph display is arranged
On this reference, the 60-minute and 12-hour chronograph recorders are combined in the subdial at 3 o’clock. Small seconds sits at 9 o’clock, and the date display is at 6 o’clock. This two-counter arrangement is a useful way to distinguish the specified 2013-era watch from descriptions of other Speedmaster generations.
The later 40.5 mm Master Chronometer collection
Omega describes a later Speedmaster ’57 generation with a slimmer 40.5 mm profile, stainless-steel cases, new colours and Master Chronometer status. The collection page lists eight models. These are collection-level details; for the movement and dial layout of an individual watch, check its exact reference rather than assuming the 2013 calibre 9300 specifications carry over.

Rank #3
- Model 331.10.42.51.01.001
Omega’s Hong Kong collection page also connects the ’57 design language to Broad Arrow hands and a tachymeter bezel. Those details express the historical influence without making the later collection an exact CK 2915 replica. Omega’s Hong Kong Speedmaster ’57 collection page.

- Start with the reference and generation. CK 2915 denotes the 1957 original; 331.10.42.51.01.001 identifies the cited 2013-era watch; the 40.5 mm Master Chronometer models belong to the later collection.
- Check the case diameter. The cited 2013 reference is 41.5 mm; Omega describes the later collection as 40.5 mm. Do not apply either measurement to the vintage original.
- Confirm movement and certification for the exact model. Calibre 9300 is documented for the cited 2013 reference. Master Chronometer status is stated for the later collection, not retroactively for the 2013 model or CK 2915.
- Look at the display and design cues. The 2013 reference has the specified combined chronograph counters at 3 o’clock and small seconds at 9. Broad Arrow hands and a tachymeter bezel signal heritage styling, not proof that a watch is the original.
For a vintage CK 2915, the reference, condition and authenticity matter when evaluating a specific watch. The Omega history page establishes the model’s identity, but it does not assess any individual example or its value.
