On-line Vintage Watch Appraisal with Valuation by: Anonymous
Hi thanks for writing in...if the bracelet is not the original the mark on the bracelet will not provide any clues or further info concerning watchmaker or the movement, only the watch strap.
You might like to try searching in the US 1922 edition of maker's marks in the jewelry resources here.
Alternatively, an on-line appraisal will provide more detailed information plus you will know the resale value and the insurance value. Have you noticed the gold prices lately? Don't make the mistake of thinking just because the strap is not the original, the piece is not valuable.
