My digital camera is still not back (see my rant about Nikon in the photography subforum of the Cafe forum...), hence I've not been posting many photos.
But I got a watch off of eBay yesterday that made me go get my daughter's Casio, which has a lousy macro function, to take some of these pictures.
The watch is a rather battered Cyma 334 from the 1930s. Nickel steel case that has seen some real battering, but the dial is okay (no pix yet...) and the reason I got it was to get the movement: it's a Cyma 334 as can be seen in this picture from Ranfft's database. This picture from Ranfft is of the 335, which he says is not different from the 334, but I'm not sure.
Now, what I have is definitely the same caliber, but with a huge difference: there is no partial plate, but rather this calibre uses a full plate! Again, sorry for the lousy picture, but this Casio just doesn't perform as well as my Nikon:
And here I've tweaked the picture a tad:
Now, the mystery deepens: this calibre doesn't have the word "Cyma" engraved on it, just:
Brevets + Patented
But these are definitely two related movememnts: the size is identical, the microadjustment is the same, and the very funky and really cool escapement looks to be identical.
The best part: spent all of €8.50 including S&H. Sometimes eBay can really be your friend.
My plans for the watch: when I have the time, it will be taken apart, cleaned, oiled, redo the face of the dial. I will work with my watchmaker here, as cleaning the geneva stripes - which are really, really nicely done, by the way - is necessary (the oils from somebody's fingerprints have marked them beyond what can be simply removed with microfibre) and I'd like to replace most of the screws (they're a tad battered) with new blued screws after getting the rest of the watch in shape. Oh, and of course a new mainspring, this one runs down after around 15 hours or so.
Inside case markings show that it was worked on in 1940, 1954, 1967, 1983, 1990 and in 2003. The case itself is, as I said, fairly battered and needs quite a bit of work on it, and I may choose instead to have it replaced, perhaps where I could put a mineral glass back on it to show it off.
But the mystery remains: surely this is a 334, but what's the deal with the full plate? I know that means that the geometrical stability of the watch is significantly improved, but is this perhaps the difference between the 334 and the 335 that Ranfft shows?
