Thank you for posting this—it is a remarkable movement. But I will say, it is not an Ultrathin. It is an even rarer caliber: the time-only variant of the Caliber 250 (aka the Dietrich Gruen), which is always shown & seen in the 23j up-down version. However, it was originally advertised as available without the up-down complication. Compare the middle bridge and center jewel—you’ll see what I mean.

This is the only one I’ve ever seen, perhaps only a handful ever made. I’ve scoured the forums for years for a live example! Congratulations!

To prove it, here is a true UT, sn 41138 (earlier than yours), already with the distinctive upturned middle bridge.

And the price guide listing...
