As of my last knowledge update in January 2022, Omega Constellation watches are known for their elegant designs and various dial color options, including white dials. The Constellation collection by Omega often features a variety of materials, colors, and styles to cater to different preferences.For the most accurate and up-to-date information on specific models, including those with white dials, I recommend checking Omega’s official website or contacting authorized Omega dealers. They can provide details on the latest releases, availability, and specific features of Constellation watches with white dials.
