Vintage Omega Flightmaster: the 910, the 911 and every reference
The Flightmaster is Omega's pilot's chronograph of 1969 to 1973: a big, heavy steel case, extra crowns, coloured hands and a second time zone. There are four vintage references and two calibres, and the calibre has to match the reference. Everything on this page is from Omega's own database and the GF 620-4 parts catalogue.

What the Flightmaster is
Omega built the Flightmaster for pilots, adding a second time zone to a manual-wind chronograph and putting the extra controls on the left of the case. Omega's own database files it under the Seamaster collection, not the Speedmaster, although its movements come from the same 860 family as the Speedmaster's 861. It is large and heavy for its time and came on an attached steel bracelet.
Every vintage reference
| Reference | Year | What it is | Calibre | Rated |
|---|---|---|---|---|
| ST 145.0013 | 1969 | The first Flightmaster, steel bracelet | 910 | 60 m |
| ST 145.0026 | 1971 | Steel, with the later calibre | 911 | 60 m |
| BA 345.0801 | 1971 | 18k gold case and gold bracelet | 910 | 60 m |
| ST 145.0036 | 1973 | Steel, uprated to 120 m | 911 | 120 m |
Source: Omega's vintage database, as held in the reference lookup, which writes the references with four digits after the dot; sellers usually list them as 145.013, 145.026 and 145.036. All have screw-in casebacks.
The 910 and 911, from the factory catalogue
| Calibre | Catalogue | Built from | Size | Beat |
|---|---|---|---|---|
| 910 | GF 620-4, folios 1–4 (1970) | 860 | 27.0 mm · 6.87 mm high | 21,600 A/h |
| 911 | GF 620-4, folios 1–3 (1971) | 860 | 27.0 mm · 6.87 mm high | 21,600 A/h |
Both are manual-wind chronographs built on the 860, with the extra works for the second time zone, and both are the same height as the Speedmaster's 861. The catalogue sections list the parts for each, and they are not interchangeable across the board. The calibre lookup has both, and the 861 parts list shows which 860-family parts are shared across the range.
Is your Flightmaster all original?
The reference, the calibre and the dial have to agree. Six photos and the weight, and I check them against Omega's own records and put it in writing. Nothing to pay until I confirm the photos can answer it.

The serial is on the movement, under the screw-in back; the serial number lookup gives the year band. It should land between 1969 and the mid-1970s, and in or after the year the reference appears in the table above.
What it's worth
A correct steel Flightmaster usually sells for a few thousand dollars, and the 18k gold 345.0801 for much more. The price turns on completeness: the coloured hands, the extra crowns and the bezel are specific to this watch and hard to replace, so a Flightmaster missing any of them is worth a good deal less. Check the "What they sold for" links above rather than asking prices. What's my Omega worth? explains the parts value too.
What goes wrong with them
Missing or wrong parts. Hands, crowns and bezels were lost or replaced, and parts from other watches were fitted. Swapped movements. Check the calibre against the reference, as above. A tired chronograph. These are complicated movements, and one that hasn't been serviced may start, stop or reset badly. Ask for a video of the chronograph running and resetting.
Buying one without getting burned
Before you pay, ask for these photos:
- The dial and all the hands, square on and in daylight. Every coloured hand should be present, with matching lume.
- Both sides of the case. All the crowns and pushers present and matching.
- The inside of the caseback. The reference.
- The movement, with the calibre number readable. A 910 or 911, matching the reference.
- A short video. The chronograph starting, stopping and resetting to zero.
Six photographs and the weight, and I put it in writing: calibre confirmed against its factory sheet, case checked against Omega's own case data, serial dated, dial judged, three honest values. Within a day. US$75, and nothing to pay until I confirm the photos can answer it.
Questions people ask
What is the difference between the Flightmaster 910 and 911?
They are the two calibres Omega built for it, both from the 860 chronograph family, both 27.0 mm across, 6.87 mm high and beating at 21,600 an hour. The 910 is the first, in the 1969 145.013; the 911 followed in 1971 in the 145.026 and 145.036. The calibre number is on the movement, and it has to match the reference.
Is the Omega Flightmaster a Speedmaster?
No. Omega's own database lists it under the Seamaster collection. It shares its movement family with the Speedmaster's 861, which is why the two are often mentioned together.
When was the Omega Flightmaster made?
Omega's database lists the first reference, the 145.0013, in 1969, and the last vintage one, the 145.0036, in 1973.
How much is a vintage Omega Flightmaster worth?
A correct steel Flightmaster usually sells for a few thousand US dollars; the 18k gold 345.0801 for much more. Missing or replaced hands, crowns and bezels bring it down, because the parts are specific to this watch. Check the sold prices on this page.
