it's my CK 2915-17 (put together in 2017). Unfortunately, not a real one... 321 base, 105.002 case, 105.003 dial, Broad Arrow "Replica" bezel... but it's fun to wear!
Little change up from Speedy Week. 16710 BLRO. Before I got it I was worried that it would be too small on my 7 3/4” wrist. I think it works. It’s as small as I’d go, and not every 40mm watch would work for me. But Rolex’s blending of case and bracelet is outstanding.
