For my Nav. I simply went back to my AD and bought what I knew was the correct bracelet. If you know the model number of your watch head and can find the correct model number that matches the correct bracelet and can find one on the internet you can save some money. Once you know what you need you can look in the forsale threads of watch Forums and look at used sellers like Bernard and if you get lucky you might find just what you need. What you are looking for is the proverbial needle in the haystack. Good luck.
Frank.
An AD is the only one I'd trust TBH.
