also known as Mondaine. In my case, the Mondaine Swiss watch with time zone indicator/display. Here’s mine, it has a third time hand to display the time in a second time time zone.
It has a 22mm strap anchor.
The upper button moves the outer bezel and thus changes the title of the time zone city which refers to the third (silver outline) hand; the button works both clock and anti-clockwise moving the bezel to left (to the west) and right (to the east). The lower button has two positions, fully extended moves the time hands, both forward and back. Pushing it in to a ½ way position and turning anti-clockwise moves the third hand, and clockwise advances the date. (I think, it might be the other way round.) NB the time is told on a 12 hour clock, the third hand & date is every 24 hours, so make sure that the time hands are in the correct half day. Actually, an hour after posting this, I found the manual, but now its on the web!
I also have a desk clock from them, which is pretty picky about the battery it uses. The batteries are best not bought from the pound shop, and this too has now stopped, it will require replacement which is not cheap.
As below, I am considering getting a Zepplin to replace it although I am using a £30 Sekonda at the moment. Zepplin may not have a direct channel, but I found First Class Watches, who claim to be the official distributor. I really want the multi time zone one, but the one’s I have found are to my eye ugly. I like the look of the Chronograph 100 year anniversary, but I don’t want a second hand, i.e. a dial measuring the elapse of a second’s time.
I wrote up how to set the time, time zone and date displays.
This has after 20 years gone. I thought I might replace it with a Zepplin; they have some neat yet expensive, even on Ebay watches
