Help authenticating Baume and Mercier chrono/diver

I cannot find a single photo of any B and M watch that looks anything like this on the interweb, which is usually a bad sign. If any of you are experts or simply know a good bit about the brand, can you please tell me anything about the watch shown? It has a Landeron 248 that is marked B and M. The dial concerns me. And I'm not inclined to think it's just ULTRA RARE. Thanks in advance for any help.

looks like a put together like those found in the Philippines. Besides the dial, the bezel insert looks like a cut down Seiko jobbie similar to those modified to fit an old 6217. the numerals are too close to the outer edge. like jaydubbya says, could be a fun watch with some sort of genuine dial installed. lots of vintage original generic swiss watches used the landeron movement so a match up would not be too difficult.
