For Fratello writer Dave Sergeant, the Calibre 321 was the right first Speedmaster because it matched a short list of personal requirements: manual winding, a straight-lug case, sapphire and ceramic rather than Hesalite and aluminum, a display back, and a dial without “Professional” text. His February 10, 2026 account is a buyer’s story, not a ranking, so its conclusion applies to his priorities rather than to every collector’s first Speedmaster.
The search that took years
Sergeant says he wanted a Speedmaster for a long time before he actually chose one. The problem was not a lack of options. The Speedmaster family spans many references and styles, and he kept delaying the decision while he compared them. Eventually he set two rules that narrowed the field: the watch had to be new or in excellent condition, and it had to be manually wound.
Within those rules he looked at three candidates, each of which he ultimately set aside for personal reasons:
| Candidate named in the article | Relevant facts from OMEGA or the article | Why Sergeant passed on it |
|---|---|---|
| Speedmaster ’57 Trilogy | OMEGA dates the original Speedmaster to 1957, and the Trilogy is the anniversary-style grouping that revisits that design. | Not stated in the article beyond “personal reasons.” |
| First OMEGA in Space | OMEGA says the CK 2998 was first released in 1959. Its 2024 model uses Calibre 3861. | Not stated in the article beyond “personal reasons.” It is a different reference and movement from the Calibre 321. |
| White-dial Speedmaster Professional | Not described further in the article. | Not stated in the article beyond “personal reasons.” |
The decision came at a Speedy Tuesday event in Hong Kong, where he tried the Calibre 321 again. He describes that second encounter as the point where the choice finally felt settled.

The priorities that decided it
Sergeant’s reasoning rests on his own preferences, and he is clear that they are his. In his account, the Calibre 321 satisfied the following:
- Manual winding. This was one of his two non-negotiable rules.
- Straight-lug case. He preferred this case shape to the alternatives he weighed.
- Dial without “Professional” text. He wanted a cleaner dial than the Professional-branded versions.
- Sapphire crystal and ceramic bezel. He preferred these to Hesalite and aluminum, which he judged less suited to how he wears a watch.
- Display back. It lets him see the Calibre 321 itself, which he considers historically important and visually compelling.
- Bracelet and clasp. He describes them as comfortable and cohesive, while acknowledging that a new owner’s enthusiasm can color that judgment.
These points work as a checklist. A buyer who values a sporty Professional dial, an automatic movement, or a lighter case may land somewhere else, and Sergeant does not argue otherwise.

Buying pre-owned, and what the account does and does not establish
Buying new was outside Sergeant’s budget. He instead found an excellent-condition, full-set pre-owned example at Swiss Horology in London. To help fund it, he part-exchanged his Rolex Explorer II. These details are his own account. They are not an independently verified transaction record, and the article does not provide prices.
He also reports two timing details: a journey home of roughly 22 hours, and a dealer turnaround of about 48 hours. Both are anecdotes from one purchase, not indicators of how long a pre-owned Speedmaster purchase typically takes.

If you are considering a pre-owned example yourself, the points his account implies are worth checking before you pay:
- Confirm the condition grade the dealer gives, and what it covers, in writing.
- Ask whether the watch is a “full set,” meaning the original box, papers, and any additional links or tools are included.
- Check the crystal, bezel, and bracelet against the description, since these are the materials Sergeant weighed most heavily.
- Ask about the return and warranty terms for the specific sale, which the article does not describe.
Historical context: what OMEGA says
Sergeant’s emotional case for the Calibre 321 leans on its history, and OMEGA’s own material supplies the key dates. The company dates the original Speedmaster to 1957. Its press room states that NASA declared the Speedmaster “Flight Qualified for all Manned Space Missions” on March 1, 1965.

OMEGA also describes a physical link to the Apollo era. Its account of Apollo 17 says the company used Gene Cernan’s historic ST 105.003 watch as the physical reference for recreating the Calibre 321 with tomography. That is a manufacturer’s statement about its own reconstruction process, and it is the sort of detail that is best read as OMEGA’s account rather than an independent measurement.

Readers often merge the two, so it is worth separating them. The First OMEGA in Space is a distinct point in the family history. OMEGA says the CK 2998 was first released in 1959, and that the 2024 model uses Calibre 3861. The Calibre 321 is a different movement and a different reference. Sergeant considered the First OMEGA in Space as one of his near choices, but his purchase was the Calibre 321, not that model.
How to use Sergeant’s reasoning for your own choice
The article does not offer a complete technical comparison, and it should not be read as one. What it does offer is a set of axes that a buyer can use to test candidates against their own priorities:
- Winding: manual versus automatic.
- Case shape and lug style, including straight versus other lug treatments.
- Movement, such as the 321, 1861, or 3861 as named in the article.
- Crystal and bezel materials, such as sapphire, Hesalite, ceramic, and aluminum.
- Dial text and color, including whether “Professional” appears.
- Bracelet comfort over a full day of wear.
- Condition and completeness, for pre-owned purchases.
- Budget, including whether a trade-in is part of the plan.
Sergeant’s closing advice, which he phrases as a short quotation, is to take your time but, when the moment comes, buy the watch you truly want.
