From the photo of your black dial Bulova and also references online, it seems that the Ord Dept watch used a smaller crown than A-17/A-17A. And agree that a large crown really makes a creamy winding; that’s what I have experienced winding my a17a 😀
Just a quick update on my meeting with the seller. Disappointingly, the watch does not look quite the same as shown in the photos; there is a dark radium burn mark of the shape of the hour hand perfectly covered by the hour hand in the photo (coincidence? I don’t think so); the rest of the burn looks just “Less brown” than the photos (thanks to Lightroom / photoshop). Wasted my lunch hour but great to have learnt some lessons.
