Building further on the mechanical concepts already presented in other watches from the Decimal Repeater collection, the caliber of the “Tantalor” 9 centers on a LeCoultre ebauche, which has been rebuilt to a decimal repeater mechanism striking hours, 10-minute intervals and minutes. The beauty of this system is that the minute chime never strikes more than 9 times, making the repeater easy to understand and more natural in actual use.
