Are there any legit/correct dials that don't say swiss?

[HiBoost]

I was looking at this listing and noticed the dial doesn't have any variation of the SWISS writing at the 6 o'clock position:

I have found a few others that look this same way, but then many more from the same time period/reference which do say T SWISS MADE T. I certainly understand that older watches may have had the dial replaced somewhere along the way, and that throughout the years the specific Swiss text has changed several times, but did Rolex ever make dials that didn't say anything down there?
