I'd like to show a few watches I have, with names ending on -tron.
The core of this bunch are Citizen Cosmotron watches 78xx (Specials) series. This are advanced electrics, and there's a lot to like about them (imho). They have 36 vph rate, pushing date-day change system, special zeroing pusher at 7 (they are sometimes referred to as "one minute chrono" because of that rare feature), great-looking monocoque cases (not every model) and funky 70s design. There's a detailed description at Sweephand's website if you are interested to read more about them. Here https://sweep-hand.org/the-x8-cosmotron/ A photo from there, describing what is "special" abut the Specials
So I've collected a bunch of them, and I also have a few watches from other brands, that used similar naming pattern (I guess that was pretty popular back then). I thought it would be nice to show them in a single thread. And now, some photos...
A group shot of Citizen cosmotrons in monocoque cases (I have a few more, but they need some more work)
Some other Cosmotrons
The red dial is a regular screwback case, the blue dial is 7804 (no zeroing pusher) and the green dial is GX - Citizen's specific tuning fork movement
GX next to the older brother
And now for some other -trons
Rado Marstron and Technos Technotron - both rocking electric ESA 9154 Dynotron
And a surprise guest - non-electric, but still -tronic Technos Hibeatron
Thanks for reading, if you have spare Movado Datron - you know whom to give it as a gift ; )
