Upon its release in 2013, the Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar was a hot property - an elegant-looking dress watch upholding one of the most difficult-to-produce watchmaking complications. Today, it savours the same standing within the maison's catalogue as well as the watch market, for a good reason. While the details and mechanism are foreseeably nonpareil, it is also quite incredible on the wrist, casting a strong, memorable presence.
The case of this Master Ultra Thin Perpetual Calendar measures 39mm in diameter and only 9.2mm in height. It enjoys a sweet spot between a large and a small watch that patrons of varied wrist sizes can enjoy. It is made of 18k white gold and is water resistant to 50 metres. It features tapered lugs with chamfered, brushed edges and a sapphire crystal caseback.
