In its vintage steel case and gradient blue dial matching the small-scale lined leather strap, the Duometre Quantieme Lunaire showcases the Duometre concept in style. The sectorized dial is finished in a variety of styles: opaline (top of dial), satin-finish (center of counters), circular blue (around counters), and sunray (power reserves). On the reverse side of this complication watch, the twin-barrel Calibre 381 – one dedicated to indicating the time, the other to complications – reveals the mechanics of its finely decorated components: sunrayed côtes de Genève, chamfered bridges, blue screws.CASE Stainless steel Diameter: 42.5 mm Thickness: 13.05mm WATER RESISTANCE 5 bar DIAL Appliqued numerals, Blue, Opaline STRAP Blue leather Interchangeable: No Lug width: 21mm Length 12h: 75mm Length 6h: 120mm BUCKLE Double Folding Buckle Stainless steel Buckle width: 18mm JAEGER-LECOULTRE CALIBRE 381 FUNCTIONS Date, Jumping seconds, Seconds, Moon phase, Hour - Minute, Twin Power-Reserve MOVEMENT Manual winding, Components: 414, Vibrations per hour: 21600, Jewels: 42, Barrel: 2, Thickness: 8.24mm, Power reserve: 50 hours
