The house has forged a unique reputation in Swiss watchmaking: not only as an integrated manufacture – one of the few to produce all its calibers in-house – but also as a movement supplier for the greatest houses, including Patek Philippe, Audemars Piguet, Vacheron Constantin, and Cartier. The Master Control collection was launched in 1992 as the brand's reference line in classic watchmaking: sober round case, uncluttered dials, traditional watchmaking complications – power reserve, calendar, chronograph, tourbillon. It is accompanied by the \u003cem\u003eMaster 1000 Hours\u003c\/em\u003e program, an internal certification of approximately six weeks of tests undergone by each piece before delivery, among the most demanding in Swiss watchmaking.\u003c\/p\u003e\n\u003ch3\u003ePersonality\u003c\/h3\u003e\n\u003cp\u003eThree off-center indications on a sober dial – power reserve at 10 o'clock, retrograde date at 2 o'clock, small seconds at 6 o'clock.
