These were not made by Omega but are high quality replacement parts manufactured in the UK.
If the back of your end link has the number 824 on it or the last three didges of the code on your clasp is 824 then these will fit your watch. The last two photos show where to find these codes (the bracelet is not included).
These will fit clasp stamped 1501/823, 1521/843, 1501/824, 1502/824 and others
