GTM-06
-
description
The GTM-06 minute repeater differs from other repeater wristwatches in a number of details. There is an acoustic reason for the large case design, as the generous case volume allows the gongs to develop a full and pure sound. The GTM-06 utilises a Cathedral gong that circles the inside of the case twice - the majority of minute repeaters have a shorter gong making just one circumference of the case - providing the fullest possible tone achievable.
The lugs are specially channelled in order to allow the resonance of the case not to be dampened by their mass. The chapter ring of black onyx is adorned with highly polished hour indexes that catch the light at every angle. It takes more than two months of intensive work in several stages just to complete the fine finishing of the components before assembly even begins.
Available with either a 18k 4N rose gold case or a 950 platinum case.
