The Superbuy Reddit community has become a hub for Rolex enthusiasts, where members collaborate to build an extensive authentication encyclopedia for the Rolex Submariner, also known as the "Green Water Ghost" or "绿水鬼" in Chinese. This collaborative effort is facilitated through the Superbuy Spreadsheet, which has become an indispensable tool for collectors and enthusiasts alike.The Spreadsheet meticulously documents 20 core differences across various generations of the Rolex Submariner, providing a comprehensive guide for鉴定 enthusiasts. For instance, it details the ceramic bezel gradient blue process of the 16610LV and the Chromalight luminescent coating decay cycle of the 126610LV, which are critical in distinguishing authentic pieces from counterfeits.Veteran players within the community actively update what they call the "Black Market Premium Alert Table," which is a reflection of the global authorized store stock data. This table helps in generating the "Buy Timing Index," a metric that indicates the optimal time to purchase a Rolex Submariner based on market trends and availability.Moreover, the Spreadsheet features a "Microscope Scale Comparison Module" that supports the automatic detection of authenticity through real-life images. This module uses advanced algorithms to compare the刻度 of the watch against known authentic standards, providing a high level of accuracy in the authentication process.For those interested in diving deeper into the world of Rolex Submariner authentication, the Superbuy Spreadsheet is available at the following external link: Superbuy Spreadsheet.
