I have decided to let go of my 37mm Waltham Centennial Bathyscaphe. If you are not familiar with these, they were manufactured by Blancpain for Waltham, which was a long standing agreement. The watch is in good condition. Case is very crisp, and I would say it has never been polished. Dial is a sunburst grey with almost mocha markers. Dial does have some patinatation near the bottom and is not perfect but overall still quite nice. There is a scratch on the caseback which you can see in photos. I had the watch fully serviced in the last year, and it keeps time very well (It was not made waterproof, however). These are virtually identical to the contemporary Blancpain version (I brought mine to the exhibition Blancpain had in NY and compared). Asking $2999. Open to F2F in NYC as well.
