It's Eddie Platt's Blancpain Fifty fathoms hommage. The PRS 50. Limited to only 50. I have No. 33. I'm allergic to rubber straps so I nipped out and bought a white stitched leather job. I took a couple of pics for comparison. Once again Eddie produces a classic. I must say that I'm partial to acrylic bezels and this one is a beauty.
