Editors’ Notes

Jaeger-LeCoultre's 'Reverso' watches are just as popular now as they were when the Swiss maison first launched them back in the '30s. In the same classic Art Deco style, this stainless steel 'One Duetto' timepiece is set with two rows of brilliant-cut diamonds framing both the white and navy faces - a carefully engineered sliding hinge allows you to flip between the two. It's powered by in-house 844 movement and has a thin bracelet strap designed to follow the curves of your wrist for a comfortable fit.

All Jaeger-LeCoultre watches still within the initial 2-year warranty period under the original International Limited Warranty will be eligible to benefit from a 6-year extension, for a total of 8 years warranty.
