This model can not be found in the catalogs but does use the case found this year. The red 21 marker is a point of contention and could be after market however, the repositioning of the Timex Logo and lack of break in the minute track suggests this could be a factory dial. I have seen this model before on eBay however what i have seen could be this piece being sold over and over again so it would even be a piece unique. I’ll keep my eyes peeled and make corrections if i find another for sale.
