Longines announced three new Flagship Heritage Moonphase versions on 3 October 2024: Havana beige, anthracite and green. They share the line’s moonphase-equipped specification; the key differences among this trio are dial colour, details such as hand and marker plating, and the coordinating strap. They are three additions, not the full range: Longines’ current US listing shows other dial variants too.
What changed with the 2024 additions?
The new colours extend a moonphase-equipped Flagship Heritage line introduced in 2023. Longines described the additions in its 3 October 2024 announcement as versions in Havana beige, anthracite and green, each equipped with a moonphase complication.

The Swatch Group archive describes the dials as sunray-finished, with applied markers and hands in rhodium or rose-gold plating; the treatment is coordinated with the moonphase indicator. Strap pairings above are the cited catalogue details, not a guarantee for every market. Check the reference and strap shown by the local Longines listing before ordering.
How do the three watches differ?
Based on the published material, this is principally a choice of colour and styling rather than a different movement or case specification. Havana beige has a brown-strap pairing, anthracite a grey one, and green a black one in the cited catalogue. The Swatch Group archive also identifies rhodium or rose-gold plating for the applied markers and hands, but the available listing details do not establish a complete, market-by-market mapping of every plating choice to each reference.

There is no objective “best” colour in the product information. Choose by the dial and strap combination you prefer, then compare the exact reference and local listing. The current US anthracite product page also presents sunray silver, opaline ivory, sunray blue, sunray green and sunray beige options, so the three 2024 colours should not be mistaken for the collection’s entire assortment.
What specifications are documented?
Longines’ current US listing for the anthracite L4.815.4.52.2 gives these specifications. They describe that listed reference; confirm the local product page for the version and market you are considering.

The Swatch Group archive identifies the movement as calibre Longines L899.5. It says the silicon balance spring and other components provide magnetic resistance ten times greater than the ISO 764 reference standard. That multiplier is the group’s manufacturer-stated comparison, not an independent test result.
What does the Flagship heritage add?
Longines describes Flagship as one of its earliest collections, dating to the late 1950s; the Swatch Group archive gives 1957 as its launch year. A signature detail is the 18-carat gold medallion on the caseback, depicting a caravel under full sail against a blue enamel sea. Swatch Group says the enamel is applied by hand and kiln-fired.
