The Duomètre 60435E1 (aka: Q60435E1), seen from the bench

The Jaeger-LeCoultre Duomètre à Quantième Lunaire 40.5 White Gold Enamel (ref. 60435E1) features the Dual-Wing system with two separate mechanisms for timekeeping and complications, synchronized by a single regulator. The caliber 381 displays hours, minutes, seconds, flying seconds, date, and moonphase within a 40.50 mm white gold case. The lug width is 20 mm, a classic manufacture measurement allowing quality aftermarket strap compatibility with curved or semi-curved extremities for optimal integration.
