Thank you for your efforts. If the movement is out of the case for any reason, I’ll look for additional marks. I think you’re exactly right about it being sort of a private label for a local New York jeweler. Again, thanks!
A quick on line check of Hamann & Koch, New York, reveals a buffet of watch and clock related listings. None of which would have been made by the firm, I’d wager. Many of those items might have the company name on them, which means they are private label items. Much the same with your box hinge watch case. Any manufacturer of a precious metal object can put his registered trade mark on the item, OR the registered trade mark of his customer , provided the customer has had his trade mark registered with the Federal Trade Commission (USA), or the Deportment of Corporate and Consumer Affairs in Canada.
