If you’re planning to keep the watch, then who cares? The cards are just useless bits of plastic anyway, even if they did match. Toss ‘em.
If you think you might sell it, then I’d price this as a watch with no cards at all, as I’d personally find mismatched cards to be the same (in terms of collector value) as a watch with none. Some people really care about having (correct) cards and would not buy one without or would deduct a chunk from the price if they were missing. Consider these missing.
No reason to compromise, I don’t think. If you care about the cards why not move on and find one with?
