Community
Owners and reviewers widely praise the Longines Flagship Heritage Moonphase for its elegant aesthetic, attractive midnight blue dial with dauphine hands and wedge indices, and the well-finished 38.5mm case with comfortable short lugs. The integrated moonphase complication is a highlight, featuring a night blue background with shiny silver stars and moon, and the L899.5 movement offers a 72-hour power reserve. However, some find the watch too thick at 12.4mm for a dress watch, with one owner noting the case back is not sapphire. The 30-meter water resistance is considered minimal, and the crown appears undersized to one reviewer. On balance, owners and reviewers rate the Longines Flagship Heritage Moonphase highly for its classy aesthetic and value as a moonphase watch.
