Before I bought the Panerai Black Seal PAM 183, I bought this RXW MM25 Poseidon. Its a Japanese company, but a Swiss Made watch made by Ken’s Trading. While it looks similar to the 183, its quite different in person and on the wrist. The watch came with two 26x26mm straps, quite different from the 26x22mm straps that come with the PAM183.

Here is the watch shown with the lizard pattern 26x26mm strap that came with it. The watch has fixed lugs so straps need to be screwed in with Rivets, making aftermarket straps very difficult to find in variety. Most will have to be custom made or have Rivets in them, which is not the best compromise because sometimes a guy just doesn’t want rivets in his strap! As you can see, it has a great sandwich dial and it glows like a torch.

Caseback is of the Solid Variety, hiding the Swiss Unitas 6497 movement inside. The caseback does proudly annouce the movement inside, as well as the 1000 Gauss Anti-Magnetic rating and 100m Water resistance. Also written on the back is “Luminova Plasmir Dial”, which means that it has a Luminova Sandwich dial.

Crown is a screw-down variety, just like the 183 but is a Brevet Swiss Crown. Its a great crown and feels good when winding. As you can see from the sideview shot, the Bezel protrudes out from the cushion shaped case a fair bit.

Here is the ever-important wrist-shot. When I got this I really really liked it… I thought it was a great looking watch and I couldn’t believe I didn’t like Radiomirs before. It wears quite a bit larger than my 183, but I have to say that after owning the 183, the RXW MM25 has lost a bit of its luster. I just did not want to wear it after getting the Black Seal, so I sold it! Bye bye MM25, but it was a great experience owning it, and I’m glad I did as it motivated me to buy the Panerai 183 Black Seal.
