Hi
And welcome to the OF. I am no pro, but am getting familiar.
First off, the 'model number' : this would be whats engraved in the case back. Yours appears to be a 175 0032. Googling this will yield a lot of information...also try the forum search -> you will get some hits.
Then the strap. Looks like a 1444 with 810 endlinks. It looks legit, but only someone with a indepth knowledge of the Reduced Speedmasters will really know (havent seen many of these folk on the forum), or lots of searching. Googling this will yield some hits.
Thats a start. Sorry I can't be of more assistance, am more into the bigger models...
Best regards,
Eugene
