It is an uncommon watch. I bought it maybe 35 years ago. At that time before the internet existed, I had never seen one of these as well. Such an unusual case for such an ordinary oyster perpetual I thought. It was if you can imagine now, sold to me for scrap metal prices because the store owner couldn't sell it. It was far more common to see textured dial Rolexes back then. White ones like this was a common as dirt
I never found my grail Bombé which was a 14kt Pink Gold watch with a matching rice link gold band. I had heard from other stores that there was a local that wore one. This USA one with a dealer installed matching JB olive link 1950s band is also rather hard to spot.
