The Tambour Minute Repeater travel watch indicates local time while a disc in the centre of the dial shows home time, which is also indicated by the chimes.

The hand-wound calibre delivers a 100-hour power reserve.

Each Tambour Minute Repeater can be personalised with initials, an emblem or another decoration in relief, taking the place of the 4 numeral beneath the subtly smoked sapphire crystal.
