Hi experts! I recently got a 2627 cal 353 for cheap, and the buckle it has is called 'Special
EK' on the main posts of this thread. I'm guessing that's not the original buckle model that the watch had, so I'm wondering if you could point me to the correct one. Judging by the squared date window and the serial on the movement, it is one of the earlier models from 1952 or 1953, if that helps to narrow down the possibilities.
The current buckle is ok and functional, but I'm just curious about it, and I might track down another one in the future in case I want the watch to be more period-correct. Thanks in advance!
