Longines’s blue-dial Spirit Pilot lineup comprises two watches in two strap configurations: the automatic, time-only Spirit Pilot and the hand-wound Spirit Pilot Flyback chronograph. The choice is less about their small diameter difference than whether you want a flyback chronograph, prefer automatic winding, and favor a steel bracelet or blue rubber strap.
Fratello introduced the four references on October 3, 2026. Longines’s official Swiss-market listing independently confirms key details for the bracelet version of the Flyback, reference L3.721.4.93.6. The comparison below uses Fratello’s reported specifications where the official listing does not establish them; it is not based on hands-on testing.

What are the four blue-dial references?
Each model is offered in the reported lineup with a steel bracelet or blue rubber strap. The final digit of the reference distinguishes the configurations listed by Fratello:
- Spirit Pilot L3.809.4.93.6: steel bracelet.
- Spirit Pilot L3.809.4.93.9: blue rubber strap.
- Spirit Pilot Flyback L3.721.4.93.6: steel bracelet.
- Spirit Pilot Flyback L3.721.4.93.9: blue rubber strap.
Longines’s official product page identifies the Flyback bracelet reference L3.721.4.93.6 as a manual-winding watch with a blue matte dial and stainless-steel bracelet. The three other reference and configuration pairings above are reported by Fratello.

Spirit Pilot vs. Spirit Pilot Flyback: what changes?
The Spirit Pilot is a three-hand, time-only automatic. The Flyback is a manually wound chronograph. Fratello’s October 3, 2026 introduction reports the following specifications; Longines’s official page also confirms the Flyback bracelet model’s diameter, winding type, approximate reserve and water resistance.
| Specification | Spirit Pilot | Spirit Pilot Flyback |
|---|---|---|
| Function | Time only; automatic, using calibre L888.4, as reported by Fratello (October 3, 2026). | Flyback chronograph; manual-winding calibre L792.4, as reported by Fratello (October 3, 2026). Longines also identifies the official L3.721.4.93.6 listing as manual-winding with flyback chronograph function. |
| Diameter | 39 mm, reported by Fratello (October 3, 2026). | 39.5 mm, reported by Fratello (October 3, 2026); Longines lists 39.50 mm for L3.721.4.93.6. |

Choose the Spirit Pilot for automatic, time-only wear
The standard Spirit Pilot suits a buyer who wants a simpler display and automatic winding rather than a chronograph. Its reported 39 mm diameter and 11.5 mm thickness make it the slimmer of the pair, while its reported power reserve is four hours longer than the Flyback’s. Those figures describe the models as Fratello reported them, not a comparative fit test.

- Stainless steel with double safety folding clasp and push-piece opening mechanism
Choose the Flyback for a chronograph and its reset-and-restart function
A flyback chronograph lets the wearer reset and restart timing in one action, rather than stopping, resetting and starting in separate steps. Longines describes the function as useful for timing successive flight stages. That is the manufacturer’s explanation of the complication, not independent evidence of real-world navigational performance. The trade-off is a manually wound watch with a thicker case and shorter reported reserve than the automatic Spirit Pilot.
What does Longines mean by a pilot’s watch with a blue dial?
Here, the description refers to pilot-watch models in the Spirit Pilot family presented with blue dials; it does not establish a separate technical category. Longines describes the Flyback as a tool for pilots and says the complication can time successive flight stages. The practical distinction for a buyer is still the one between the automatic, time-only Spirit Pilot and the manually wound Flyback chronograph.

How much do the blue-dial Spirit Pilot models cost?
Fratello reported these euro prices on October 3, 2026. They are date- and market-specific reported figures, not a promise of current price or availability in every country.

What is known about the Flyback’s history?
Longines’s official product copy says its first flyback-equipped model dates to the early 1930s and that the brand secured a patent on June 16, 1936. Fratello instead reports a 1935 filing date for Longines’s flyback chronograph patent. The available sources do not explain whether those dates refer to different milestones, so they should not be treated as a single reconciled chronology.
For reference L3.721.4.93.6, consult Longines’s official product listing. Fratello’s October 3, 2026 introduction is titled “Not Completely Out Of The Blue: Introducing The Longines Spirit Pilot And Spirit Pilot Flyback With Blue Dials”.
