2021 Rolex Explorer numerals are now filled with luminescent material

Rolex reintroduces the size of original model that was launch in 1953 for the 2021 new-generation Oyster Perpetual Explorer.  The 36 mm Explorer is released in a yellow Rolesor, the combination of 18 ct gold and Oystersteel.  Rolesor has been a signature feature of the brand since 1933, when the name was registered.  On the yellow Rolesor version of the new-generation Explorer, the bezel, winding crown and center links of the bracelet are in 18 ct yellow gold, while the case and outer links of the bracelet are in Oystersteel.

Rolex new-generation Explorer’s 36 mm Oyster case is guaranteed waterproof to a depth of 100 meters (330 feet).  Its middle case is crafted from a solid block of Oystersteel.  The Twinlock winding crown, fitted with a double waterproofness system, screws down securely against the case.  The crystal is made of virtually scratchproof sapphire.  The black dial, now lacquered, supports the index hour markers and 3,6, and 9 numerals.  The latest model’s characteristic 3, 6 and 9 numerals are now filled with a luminescent material emitting a blue glow, like the hour markers and hands.

The new-generation Explorer is equipped with calibre 3230, a movement entirely developed and manufactured by Rolex that was released in 2020. Calibre 3230 incorporates the Chronergy escapement patented by Rolex, is made of nickel-phosphorus and also insensitive to magnetic fields.  The movement is fitted with an optimized blue Parachrom hairspring, manufactured by Rolex in a paramagnetic alloy.  The blue Parachrom hairspring is equipped with a Rolex overcoil, ensuring the calibre’s regularity in any position. The oscillator is fitted on the Rolex-designed and -patented high-performance Paraflex shock absorbers, increasing the movement’s shock resistance.  Calibre 3230 is also equipped with a self-winding module via a Perpetual rotor, with the power reserve extends to approximately 70 hours.
