I've been looking for some information about the collaboration that Tiffany and Concord had together. I've seen a few watches that were marked Tiffany on the dial, but the movement was made by Concord. I've even seen a few with both company's names on the dial. However, I've come up with very little about how long the two companies had a partnership and how much was done by Concord in terms of supplying a finished watch.
Does anyone know anything about this partnership? Was Concord just one of many suppliers used by Tiffany? Was the agreement for only certain types of watches e.g. time only or triple calendars? I imagine I'm not the only person who's looked for answers.
Thanks in advance everyone.
