(this one is for @chronotriggered )
I was researching my Westclox watch today (Model 38402 from 1965-1966, as it turns out) by going through the excellent archive of data found at https://clockhistory.com/, mentally thanking whomever uploaded decades' worth of catalogs, and ran across this marketing piece in a Westclox catalog from 1970, talking about the superiority of jeweled-lever movements over pin-lever movements.
On top is the Seiko 66B that Westclox used at that time, marked A-201 (they also used a 7 jewel version marked D-407; I have one on the bench from 68-71). I'm not sure what the bottom one is, though I suspect it's the same pin-lever movement that Westclox themselves used in their cheaper offerings.
Anyway, thought it was interesting to look at. Also interesting - note in the text at the bottom about what the FTC considers "water-resistant."
I like things that don't cost a lot; if that means I buy something broken and DIY a fix, so much the better!
