True moon-phase complication in a 30.5 mm Longines Heart design -- double-coated synthetic sapphire crystal, mother-of-pearl dial, Roman indices.
The Longines Heart Moon complication is one of the most poetic complications in dress watchmaking, and this 1:1 mirror-grade replica captures every nuance. The 30.5 mm round 316L steel case houses a true moon-phase display that completes one full cycle per month, just as the original does. The dial is dressed in a deep-sea mother-of-pearl shell face with Roman numeral indices and a refined three-piece case construction. Protecting it all is a double anti-reflective synthetic sapphire-coated crystal -- a specification matched to the reference data of the retail piece. The steel folding-clasp bracelet snaps shut with confidence, and a premium imported calfskin strap alternative is also included. Tri-code authentication (case back, hang tag, warranty card all matching) rounds out the package.
The moon phase hand is functional -- you set it at purchase and it tracks the lunar cycle, needing a small manual correction about once a year.
Sapphire-coated means a mineral glass crystal with a sapphire hardness coating on top -- it resists scratches very well and is much clearer than plain mineral glass.
Yes, 30.5 mm is a classic ladies dress size -- slim enough to wear under a blouse cuff and elegant for formal occasions.
