It took 8 years of hard work alongside a team of sound engineers and specialists at the Brassus factory to develop and fine tune a watch with a minute repeater of exceptional sound quality. The sound, volume, transmission and tone were all meticulously dissected and analysed then redesigned and put into the heart of the Royal Oak Concept. The watch has a 44mm titanium case topped by the famous titanium screwdown octagonal bezel. The in-house manual wind calibre brings to life the time and chronograph functions. The partly openwork black dial bears the minute track on the chapter ring and the tourbillon at 6 o’ clock beneath two openwork luminescent hour and minute hands. An orange central seconds hand tracks the seconds whilst the 30 minute counter lies at 3 o’ clock. Price upon request
