Hi everyone, I have a question regarding the Reference Number for this vintage Constellation. https://relojesvintage1ebay.slickpi...meter-18K-Gold-Cal-551/photo/15050778/piepan/ In the old German and English ads, the Ref. for 18k Gold version of the watch is listed as either Ref. 7025 or Ref. 7035, but the case back of the actual watch shows Ref. 14381/2 SC-6. If I google Ref. 14381, I can see similar Constellations, but if I google Ref. 7025 or 7035, I can't. Does anyone know why? Thank you for your time!
