Thanks for the info Blomman!
Would you know if there's any more detailed info or vintage Ad or any reference of this LeCoultre Quartermaster?
Really interesting watch, I want one, tried to search in 'the bay' but no luck. Unlike other American LeCoultre, or Galaxy, Future matic etc this one seems to be very very very hard to find..... Eventhough it's called Quartermaster, the demand (try not to say 'price' here) is not a quarter of the more common Master Mariner
Keep hunting now
Thanks
Dony
