Kelton was a French brand of watches purchased (?) by Timex to service European markets. I’ve mentioned elsewhere on this website that i think the vintage watches produced by Kelton appear to be of a higher quality than their Timex counterparts.

The stand out vintage watches in this Kelton catalog from 1971 are the black dial with red seconds track found on page 2 and the square dialled calendar watches in white and red on page 5. You can also find the popular Bullseye and Blackjack models too.
