Jaeger-LeCoultre's watches are so impressive that other brands have been known to use the 'blueprints' of their past models, positioning the Swiss label as the industry standard. This 'Master Ultra Thin' reference is powered by a 896/1 automatic movement that's built using 223 parts that are all handmade and assembled in-house. Set with 80 sparkling diamonds totaling 0.56-carats, the 18-karat rose gold case houses a sunray-brushed silver dial featuring a small seconds sub-dial above the six o'clock mark. The sapphire glass lens is scratch-resistant, while the alligator strap can be adjusted to fit slender wrists.
