The Omega Seamaster 300 reference 165.024 is a later, time-only version of the original Seamaster 300 family, generally dated to around 1963–64 onward and associated with the automatic caliber 552. It is not a single fixed configuration: dials, hands, bezels, crowns, cases and movements vary, and service replacements can complicate claims of originality. When buying one, assess the complete watch against its claimed period and history; a serial number, attractive patina or military-style feature cannot authenticate it alone.
What is the Omega Seamaster 300 ref. 165.024?
The Seamaster 300 debuted in 1957. The specialist OmegaSeamaster300.com collector guide covers the later 165.024 and date-equipped 166.024 family across a production period it places at 1963/64–1969. It associates the 165.024 with caliber 552 and the 166.024 with a date display and caliber 565. Auction catalogues also document 165.024 examples fitted with caliber 552.
“Seamaster 300” describes the model family, while 165.024 is the reference buyers need to evaluate. Do not assume every vintage Seamaster 300—or every watch advertised under that name—has the same reference, movement or configuration. Check the reference and movement on the actual watch and compare them with its records.
Why do 165.024 examples look different?
The collector guide catalogs four dial types, four hour-and-minute hand sets, eleven bezels, two cases and five movements across the 165.024/166.024 family. Those are the guide author’s catalogued variations, not Omega-published production statistics; the guide describes its study as ongoing, and gives no publication date for those counts.

Some differences reflect production changes; others may result from service or parts replacement. The guide notes that entire movements could be swapped, and that bezels and other components were replaced. It cautions that vintage-watch study is a matter of probability because production methods decades ago did not deliver the precision expected today. A serial number can help assess plausibility, but the guide treats serial dating as a guideline, not conclusive proof of originality.
| Feature | What the guide or catalogues establish | What that means for a buyer |
|---|---|---|
| Dial | The guide describes small- and large-triangle designs. It associates the large triangle with a 1966–67 design change. | Check the dial’s design against the claimed period; a dial variant by itself does not prove originality. |
| Hands | The guide catalogs four sets of hour-and-minute hands and associates sword hands with the 1966–67 design change. | Assess the hands together with the dial, case and documented service history. |
| Bezel | The guide catalogs eleven bezel variations, including changes in fonts and luminous-marker configurations, and notes service replacements. | A bezel that differs from an expected period configuration may reflect service or a parts change; investigate rather than treating it as automatic proof of a fake or an untouched watch. |
| Crown and case | The guide describes a transition from a naiad crown to a screw-down crown during the production period and catalogs two cases. | Evaluate the crown and case as a combination, for the particular watch’s date and service history. |
| Movement | The guide associates the 165.024 with caliber 552, but says movements were sometimes changed during service. | Request movement photographs and records; a matching caliber alone does not establish that the movement is original to the watch. |
How military-issued examples differ from civilian watches
Military-issued 165.024s are a distinct subset, not a template for every civilian example. Auction catalogues describe military watches with fixed strap or spring bars, screw-down crowns, sword hands, tritium markings and military caseback engravings. Those traits are relevant when a watch is represented as a military issue; their absence does not, by itself, disqualify a civilian 165.024.

British Army examples
Sotheby’s catalogued a 1967 British Army 165.024 with a caliber 552 automatic movement, a 42 mm case and military caseback markings. Its catalogue describes fixed strap bars, a screw-down crown, sword hands, luminous tritium markings and a W10 Army prefix. For that particular lot, Sotheby’s says an accompanying Omega Archives Extract confirmed production on 2 May 1967 and delivery to the British Army. That documentation supports the provenance of the cited watch; it does not authenticate other watches with similar markings.
Royal Navy examples
Sotheby’s describes a Royal Navy example with fixed spring bars, an encircled T, a screw-down crown, caliber 552 and a 0552 engraving. Phillips catalogued a separate circa-1970 Royal Navy ST 165.024 with fixed spring bars, a thin encircled-T dial and military caseback marks. These catalogue descriptions show that military specifications and markings should be assessed in the context of the claimed branch and provenance, not treated as universal 165.024 features.

Military inscriptions can encode branch, stock or specification, issue and year information. Compare each watch’s specific markings with reliable documentation and its claimed history. A military-looking engraving or a familiar prefix is not a substitute for provenance.
What to inspect before buying a 165.024
- Establish exactly what is being offered. Ask the seller to confirm the reference, whether the watch is represented as civilian or military, and the basis for its claimed production date. Request clear, well-lit photographs of the dial, hands, bezel, case sides, crown, caseback engravings and movement.
- Assess the dial and hands as a pair. Compare their design with the claimed period, including the guide’s noted small- and large-triangle dial variants and the 1966–67 change associated with the large triangle and sword hands. Look for consistency across components, but do not use patina alone to diagnose authenticity.
- Check the bezel configuration and condition. Compare its font and luminous-marker layout with the claimed configuration. Because service bezels and other replacements are documented, ask whether the bezel is believed to be original, replaced or of unknown history, and what supports that claim.
- Examine the crown and case together. The guide describes a change from the naiad crown to a screw-down crown during production. Ask about the crown’s history and have a qualified watchmaker assess condition and function; the crown type alone cannot settle originality.
- Verify the movement and its records. A 165.024 is associated with caliber 552. Ask for a movement photograph and any service invoices or other records. Since movements could be swapped during service and serial ranges are only guidelines, do not treat a movement serial as definitive proof that the movement left the factory in that watch.
- For a military claim, scrutinize markings and provenance. Photograph and document the full caseback and any military inscriptions, then compare them with credible records for the claimed service history. An Omega Archives Extract supported the specific 1967 British Army lot described by Sotheby’s; that fact does not establish the provenance of another watch.
- Evaluate condition and documentation before deciding. Request service history, invoices, provenance documents and additional images if anything is unclear. Have the complete watch assessed by a specialist familiar with vintage Omega references before relying on a seller’s originality claim.
What do auction figures say about value?
Two published military-lot figures illustrate why a sale estimate or result should not be read as a general valuation for any 165.024. They concern different watches, dates and types of auction figure.

Condition, configuration, originality and documented provenance can materially affect an individual sale. The collector guide also lists older price bands, but their date is not stated; they should not be presented as current market prices.
