First introduced in 1992, Jaeger-Le Coultre's Master Control collection receives a 21st-century update by way of this style. Its minimal aesthetic has been reimagined with a horological complication in the form of a moon phase aperture - a feature for which the watchmaker became well known in the '40s and '50s - offering a complete calendar alongside the day and month. Fitted with a new-generation calibre that boasts a power reserve of up to 70 hours, invest in this timeless design for a watchpiece that will pay dividends for decades to come.
