Portugieser Minute Repeater

It took 50,000 hours to develop the highly complex minute repeater strike train for the Grande Complication and the Portuguese Minute Repeater. It is operated by an eye-catching repeating slide on the left-hand side of the case and chimes out the time in crystal-clear tones: the hours on the lower-pitched of the two gongs, followed by a double strike on both gongs for the quarters and finally a single strike on the higher-pitched gong for the minutes. Every gong is individually handmade and carefully tuned for pitch and tonal purity. The all-or-nothing piece, as it is known, ensures that the mechanism will never chime out an incomplete – and thus incorrect – series of acoustic tones even if the repeating slide is released too early
