Can Anyone Tell Me Anything About This Stopwtch

This used to belong to my grandfather and as far as I know he used it at work when he was doing time and motion probably in the 1960's

I presume the large numbers 10 - 90 are seconds, if that is the case then it appears to be running slightly fast, is this normal ?

It's actually a decimeter stopwatch—those aren't seconds, but 1/100th of a minute markers, with the subdial at 12 registering elapsed minutes. I couldn't tell you much more past that.

Cool piece of kit, they’re not hugely valuable as they’re for a purpose where they’ve largely been replaced but still a really interesting stopwatch and a cool family heirloom

Prestons of Blackpool were suppliers of mail-order watches for science & industry. They seem to have specialised in Omega and stop-watches. Chronosport in Bath were the heavyweights for Heuer & Breitling watches and sporting applications. The back pages of MotorSport magazine in the 1960s and '70s always had an advert for Prestons, and for a subscription the whole run of MotorSport since the 1930s has been scanned. I did grab copies of some of Prestons' ads a while ago but I think they've been consigned to a back-up memory stick.
