I have just purchased a very rare Breitling Professional 300T Quartz dive type watch from around 1983. There appear to be many similarities to the Doxa's of that era and I'm wondering if the bracelet could have originated from the same supplier as the Doxa BOR bracelet. My main interest is because the bracelet is much too short for my 8" wrist and I'd like to find spare links if available. The end links of the bracelet are marked 028029-1 and it says Expandro, stainless steel, made in W-Germany, DB Pat 2111820. Not sure if this is an aftermarket bracelet similar to the Doxa BOR or made by the same company. Any thoughts appreciated.
