The Master Ultra Thin 1272510 (aka: Q1272510), seen from the bench

The Jaeger-LeCoultre Master Ultra Thin reference 1272510 is a 38.5mm pink gold dress watch from the Master family, founded in 1992. It houses the caliber 896, a flat manual-winding movement with hours, minutes, and small seconds at 6 o'clock. The 20mm lug width ensures visual continuity between case and strap, with satin and polished gold surfaces requiring precise finishing.
