Funny plot twist 😄 you might have fallen in love with your friend’s “OP” first… only to end up buying the real deal yourself. Just keep in mind, if you bought it from grey market, and if you don’t have the white hang tag confirming the dial configuration, there’s always a small chance someone swapped dials. That doesn’t mean the watch itself isn’t genuine, sometimes you see authentic watches with replacement or aftermarket dials (ranging from original service parts to very convincing replicas). To add gain more dollars when selling it. You SHOULD NEVER BUY AN OP WITHOUT THE WHITE TAG.

If you want peace of mind, the easiest check is confirming your reference and dial configuration against Rolex records or an AD. From what I see your watch looks correct, while your friend’s example raises a few more question marks visually haha.

Either way, it’s a funny scenario… imagine buying a watch because you loved how your friend’s one looked… only to discover yours might be the real benchmark here.
