The Sugargoo Reddit community has become a hub for Rolex enthusiasts, where members collaborate on a shared spreadsheet to build an encyclopedia of authentication knowledge for the iconic Rolex Submariner, commonly known as the "Green Water Ghost" or "绿水鬼" in Chinese.This comprehensive spreadsheet, accessible at https://www.sugargoospreadsheet.shop, meticulously documents 20 core differences across various generations of the Submariner, providing a valuable resource for collectors and enthusiasts alike.Key features of the spreadsheet include:- Detailed analysis of the gradient blue process on the ceramic bezel of the 16610LV, a distinctive feature that sets it apart from other models.- Information on the Chromalight luminescent coating on the 126610LV, including the decay cycle of the nightlight, which is crucial for determining the authenticity of the watch.Seasoned players within the community actively update a "Black Market Premium Alert Table," which takes into account global authorized store stock data to generate a "Buy Timing Index." This index helps potential buyers understand the best times to purchase a Rolex Submariner based on market trends and availability.Additionally, the spreadsheet includes a "Microscope Scale Comparison Module" that supports the automatic detection of authenticity through real-life photographs. This tool leverages image analysis to compare the刻度比对 (scale comparison) of the watch, ensuring that even the most细微的 details are accounted for in the authentication process.The collaborative nature of the Sugargoo Spreadsheet has made it an indispensable tool for the Rolex community on Reddit, fostering a culture of knowledge sharing and collective expertise in the world of luxury watch authentication.
