As of my last knowledge update in January 2022, Omega Seamaster watches with white dials are part of the collection and are known for their elegant and classic aesthetic. However, for specific details on the latest models or variations with a white dial, including materials, features, and availability, it is recommended to check Omega’s official website or consult with authorized Omega dealers.Omega regularly releases new models and updates to their collections, and the availability of specific variations may change. Official channels like Omega’s website or authorized dealers can provide the most accurate and up-to-date information on the Seamaster models with white dials.
