The oscillator, the true heart of the Rolesium Rolex Oyster Perpetual Yacht-Master Replica Watch, has a blue PARACHROM hairspring patented and manufactured by Rolex in an exclusive alloy. Like all PERPETUAL movements, the 3135 is a certiﬁed Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Ofﬁcial Chronometer Testing Institute (COSC) tests. The dial harbours large CHROMALIGHT hour markers and hands ﬁlled with luminescent material that emits a long-lasting blue glow, offering exceptional legibility in the dark.
The winding crown, ﬁtted with the patented TRIPLOCK triple waterproofness system, screws down securely against the case. It is protected by a crown guard that is an integral part of the middle case. The Rolex Oyster Perpetual Yacht-Master Replica Watch crystal, with a CYCLOPS lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof synthetic sapphire. The waterproof OYSTER case ensures optimal protection for the YACHT-MASTER’s high-precision movement.
The bidirectional rotation system on the bezel of this new YACHT-MASTER has been entirely rethought. It is based on a 120-position notched ring and a trigonal spring providing a constant torque in both directions, ensuring minimal wear and highly precise manipulation. The bezel with raised graduations contributes greatly to the unique identity of the model and its functions.
The Rolex Yacht Master Replica Watch is equipped with calibre 3135, a self-winding mechanical movement entirely designed and manufactured by Rolex. Its architecture, like that of all OYSTER watch movements, makes it singularly precise and reliable.
The characteristically shaped middle case is crafted from a solid block of particularly corrosion-resistant 904L steel. The ﬂuted case back is hermetically screwed down with a special tool exclusive to Rolex watchmakers. Insensitive to magnetic ﬁelds, the PARACHROM hairspring offers great stability when exposed to temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks.
The oscillator, the true heart of the Rolex Replica Watch , has a blue PARACHROM hairspring patented and manufactured by Rolex in an exclusive alloy. Made entirely of 950 platinum, with polished graduations standing out against a sand-blasted ﬁnish, it can be easily set to time a period of up to 60 minutes – for example the sailing time between two buoys – or to provide a reminder of elapsed time.
