The storyWhy this reference matters

When Longines launched the Spirit in 2020 it did something nobody expected: it copied nothing. The brand sits on an aviation archive that makes your head spin — Charles Lindbergh and his 1927 Atlantic crossing, Amelia Earhart, Howard Hughes — and the Spirit reproduces none of it. This is a pilot's collection drawn from scratch, in modern proportions, rather than an enlarged photocopy of a museum cabinet.

The five stars under the logo are the most interesting thing on the dial. On old Longines watches, stars recorded the grade of the movement and its chronometer status — a footnote for people who knew. The Spirit takes the symbol back but makes itself earn it: every model in the collection goes through the COSC, which in this price bracket is still the exception rather than the rule.

The engine is the L888.4, a cousin of the L888 with a silicon hairspring and a chronometer certificate. It runs at 25,200 vibrations per hour, an unhurried pace that buys autonomy. In 2020 Longines quoted 64 hours of reserve; today the official spec for this reference says 72, so the same model tells different stories depending on the year it was built. The 10 bar and the screw-down crown do the rest: a pilot's watch you can also get wet.

IdentificationHow to tell it apart

This reference is the 40 mm Spirit with matte black dial and steel bracelet; the final 6 is the bracelet, while versions ending in 0 and 2 come on straps. Under a loupe the applied numerals carry a polished rim, and behind them the steel track is pierced with lume-filled diamond shapes — a trick that gives depth to a dial that looks flat from across a room.

The five stars sit at six o'clock, under the word Longines, and they are the collection's signature. The crown is onion-shaped, screws down, and stands proud just far enough to work with gloves on. The case is 40 mm, 49.6 mm lug to lug and 12.2 mm thick, with long pointed lugs that stretch its presence: on the wrist it behaves like something rather larger than the spec sheet suggests. Straps are 21 mm.

Don't confuse it with the Spirit Zulu Time, which adds a fourth 24-hour hand and a graduated bezel, or with the later Spirit Pilot. And don't go looking for it in the Heritage catalogue: the Spirit reissues no old model, so anyone selling you one on the strength of its 1930s original is inventing that original.

CollectingWhat collectors check

Papers first. The COSC is the Spirit's central argument, and an example arriving without certificate or card loses no accuracy but does lose part of its story and part of its resale value. Ask for photographs of the certificate and check the reference matches. On a watch whose identity is five stars, documentation counts for more than usual.

Watch the lugs for wear. They're long, sharp, with a polished chamfer, and that's the geometry that survives an amateur's polishing wheel worst: go a fraction too far and the tip rounds off and the watch loses the profile that makes it recognisable. Look at the case side-on against a pale background and compare one lug with the other — the fastest way to catch an uneven polish.

And find out what reserve your particular example has. The first Spirits were sold with 64 hours, the current ones with 72. Wind it fully on a Friday and see whether it's still alive on Sunday: a thirty-second test that also tells you the state of the mainspring. If it stops well short of what was advertised, that isn't a factory fault — it's a movement asking for a service.
