The Presage Classic Series SPB471J1 wristwatch is powered by the 6R5J caliber, a new caliber from the 6R movement family that offers a 72-hour power reserve. The curved and textured dial is inspired by the softness and fluidity of silk, whose use is intimately linked to Japanese culture. The case is curved, and the dual-curved sapphire glass follows the contours of the domed dial. A new multi-row bracelet, with a design inspired by the 1970s, provides a feeling of elegance and comfort on the wrist.
