Longines La Grande Classique Heart Moon 1:1 rep — true moonphase complication, Roman-numeral mother-of-pearl dial, 316L steel case, sapphire-coated crystal, 30.5 mm.
The Longines La Grande Classique Heart Moon is a study in restrained elegance, and this 1:1 UA replica is built to match its every specification. The 30.5 mm round three-piece case is machined from 316L stainless steel and houses an imported quartz movement that keeps accurate time straight out of the box. The signature feature is the premium moonphase complication: a rotating disc that tracks the lunar cycle, completing one full revolution per month in accurate step with the actual moon. The dial is a Grade-A deep-sea mother-of-pearl face with Roman numeral hour markers and a slim baton seconds hand. The crystal is a dual-coating synthetic anti-scratch sapphire, matching the original's scratch resistance specification. A precision-folded stainless steel bracelet with an original-style tri-fold clasp rounds out a watch that wears as well in an office as it does at a formal dinner.
The quartz movement keeps time reliably within standard quartz accuracy (+/- 15 seconds per month). It's suitable for daily wear.
The dial features a mother-of-pearl surface that matches the visual iridescence of the retail piece, with the heart cutout and moon phase display accurately reproduced.
The case measures approximately 29mm, consistent with the retail La Grande Classique Heart Moon -- a classic ladies' dress watch proportions.
