The Master Ultra Thin 1682410 (aka: Q1682410), seen from the bench

The Jaeger-LeCoultre Master Ultra Thin 1682410 (Q1682410) is an ultra-flat timepiece in 40mm pink gold case featuring a visible flying tourbillon movement. It houses the in-house caliber 978G, a manufacture movement developed to achieve just 4.05mm total thickness while managing hours, minutes, seconds and tourbillon complication. The 20mm lug width is standard for the Master Ultra Thin family, requiring a strap with contained padding of 2.5–3.5mm to maintain the watch's visual balance.
