The Master Ultra Thin Q1313581, seen from the bench
The Jaeger-LeCoultre Master Ultra Thin Q1313581 belongs to one of haute horlogerie's most rigorous dress watch families. The 41 mm white gold case houses the caliber 362 movement, integrating a flying tourbillon and minute repeater complication. The 18 mm lug width is native to this reference and cannot be changed without compromising the watch's visual symmetry. The ultra-thin profile emphasizes mechanical discipline over volumetric ostentation.
