Teacup Watch - Pink Round Ingersoll Box Variant

This is the round box variant, pink with line art and Ingersoll instead of US Time on the lid. This particular set also has the watch variant with the pink plastic case instead of the chrome/stainless one. I have not been able to figure out exactly where this falls in the timeline, I was always under the impression that the Ingersoll brand name went away once the company started going by US Time.
