Exploration Legacy The Explorer collection was born from Rolexs deep involvement with pioneering expeditions. Designed to withstand extreme conditions, the Explorer is a robust and reliable companion for those who push boundaries. Its legible dial and durable construction reflect the brands commitment to precision and adventure. Purposeful Design This reference 214270, from 2016, features a 39mm case in Oystersteel with a smooth fixed bezel. The black dial is marked by oversized Arabic numerals at 3, 6 and 9 oclock, powered by the calibre 3132 automatic movement with a power reserve of approximately 70 hours. Completed with the Oyster bracelet featuring Easylink and Oysterlock, this mid-size model is built for clarity and endurance.
