Correct. My original 2231.80 came with a white outline date box. My most recent service (got it back FEB 2025 with a dial replacement that had no white outline date box). It also had a replacement watch back that had the Omega global service logo etched on it. All new to me. Owned this watch for almost 30 years with multiple services. The explanation form Omega when asked about the date box was that as the hour lumes dull over time, the white outline date box was “out of balance” with the rest of the dial. So they removed it to balance the aging of the dial. Obviously a style issue as the outline makes no difference in the visual operation of the watch. All that being said, and admittedly biased, I think the 2231.80 is a woefully under estimated model in the Seamaster line. Light, thin and no longer in production. All pluses to me! Here is a post service pic.
