Thanks to my friend @Optimizer13, I now have a gorgeous 145.016 (cal. 861, reverse panda) to pair with my 145.006 (321).
It will fit, it's essentially the same case. The bracelet is marked ST 1116 148, with 548 end pieces.
Always love a good panda dial! I especially like the 861 version of these as you get the ease of parts availability in servicing with a very cool vintage Seamaster, exceptional value and the best of both worlds.
Well the one on the far right is kind of a panda with conjunctivitis (@adam78 @MSNWatch @LouS I may be a lowly engineer but I can do bad medical jokes too )
I commented on your pic in the what have you just bought thread, but now I've seen this with yet more pics I have to comment here aswell. That thing is just beautiful, amazing to think it hasn't been revisited yet (I know we have the ST but this is something different entirely), I'm sure there would be huge demand for a reissue. Well done on such a great pair, never let them be parted(unless you're selling one to me )
