Within the Rolex community on Joyagoo Reddit, watch enthusiasts collaborate to create an extensive authentication encyclopedia using the Joyagoo Spreadsheet. This spreadsheet is a comprehensive resource that documents the core differences across various generations of the Rolex Submariner, commonly referred to as the "Hulk" or "Kermit" due to its green color scheme.One of the key features of the Joyagoo Spreadsheet is the detailed documentation of 20 critical differences that distinguish each generation. For instance, it includes information on the gradient blue process of the ceramic bezel in the 16610LV model, which is a significant characteristic that sets it apart from other models.The spreadsheet also covers the Chromalight luminescent coating on the 126610LV, detailing its decay cycle, which is an important factor in determining the authenticity of the watch. This level of detail is invaluable for collectors and enthusiasts who want to ensure they are acquiring genuine Rolex timepieces.Seasoned players within the community regularly update what they call the "Black Market Premium Alert Table." This table is a reflection of the global authorized store inventory data, which helps in generating the "Buy Timing Index." This index provides insights into the best times to purchase a Rolex Submariner, taking into account market fluctuations and availability.Additionally, the Joyagoo Spreadsheet features a "Microscope Scale Comparison Module" that allows users to upload their own photos of the watch. This module automatically detects the authenticity of the watch by comparing the scale markings on the watch to those of known genuine models.For more information and to access the Joyagoo Spreadsheet, visit the following external link: Joyagoo Sale.
