The Master Extreme 205C570 (aka: Q205C570), seen from the bench
The Jaeger-LeCoultre Master Extreme Q205C570, launched in 2012, features a 46mm case crafted from grade 5 titanium and black ceramic with a rotating ceramic bezel and screw-down crown. At its core beats the in-house Jaeger-LeCoultre caliber 757 movement, integrating hours, minutes, adjustable 12-hour subdial for a second time zone, day/night indicator, date, and a column-wheel chronograph with power reserve display. The 20mm lug width is precisely proportioned to the generous case diameter, ensuring visual balance between case and strap.
