hi, I recently purchased my first Omega and it has a bracelet end piece missing. It is a 166.026 automatic cosmic, which after scouring records came with a leather bracelet in 1967, but also had a BOR as an accessory, i think. Hopefully the watch strap is the original, but i am having difficulty locating a 7 row end piece. It has a 523 stamp on the remaining end piece. Do i keep watching ebay, or are there any informed members with better ideas as to locating an end piece? Also is there a reference anywhere of bracelet numbers used on Omegas? many thanks
