Swiss Railway Watch
also known as Mondaine. Here’s mine, it has a third time hand to display the time in a second time time zone.
I tested it on 19th August 2013, and it seemed to need a battery replacement. Otherwise OK. [Maybe not, the time zone adjustment winder is a bit fragile.]
It has a 22mm strap anchor.
I also have a desk clock from them, which is pretty picky about the battery it uses. Best not bought from the pound shop.
