It seems my Gubelin streak has continued with the latest arrival: a Gubelin Triple Date Moonphase. Likely from the 1940s-1950s. This guy will need some rehab to get back to its former glory, but the dial looks to be in quite good shape for its age, and I'm guessing that it's an original dial based on the sharpness of the print and the old radium (?) dots above the hour markers. Would love to hear your thoughts on the dial.
On opening the case back, I was slightly surprised to see that the movement and case back are unsigned. The inside case back is marked "ACIER *INOX*", "SWISS MADE", and 94309. The movement has what looks to be a Valjoux ebauche, followed by crisp "06". I looked very carefully to confirm the caliber number, as I was surprised that it wasn't a Valjoux 90. An 06 isn't in the Ranfft movement database, and the only other reference to it that I found was in this ebay auction for a Tacar Triple Date Moonphase. So I know they exist, I just don't know anything about this movement, nor their reputation, though I seem to recall that the Valjoux 90 is considered a well made and reliable movement. The movement is 25 mm in diameter and the case is just over 36 mm in diameter without the crown.
I should probably make a separate thread, but does anyone have any recs for a good watchmaker in New York City to service this guy? It would be nice if it were local, but I'm not opposed to shipping it off for service if there's a watchmaker who loves working on these kind of vintage Valjoux manual movements and is more reasonably priced.
