Crazy love for it here! I couldn't quite stretch to any that were on the market but snapped up a Black Bay 41 when it appeared and I've no regrets. Easily the best watch I've owned. The fit, the finish, the feel. Amazing stuff.
The BBB is the best colour in my opinion and if I didn't already have the 41, it would be my next watch.
Oh and mine is ETA but dunno well within Rolex standards, never mind COSC - under a second per day deviation!
