The automatic bumper movement runs strongly and keeps time. The watch is triple signed on the case, dial and movement. The Master Mariner is a highly sought after model within the Jaeger LeCoultre range but vintage models are rarely seen coming up for sale. So I was very pleased to acquire this watch.
If you are looking for a vintage high end watch that will last for many years if correctly serviced when required, you must not let this timepiece pass you by.
