hello Johvic ..
firstly that's a nice catch!!
the bracelet appears to be an original seiko, I wouldn't know if original to the watch but it's the same one I have on my 6139-6005 except with different endpieces. If I am correct, it should have STL Stelux on the clasp - these are premium quality bracelets and they look beautiful too .. I wouldn't replace that!
the crystal is probably salvageable .. i've just done one of mine as follows ... first a rub with 400 grit dry sandpaper, then a rub with 1200 grit wet/dry, followed by a rub with a tissue and some 'peek' (which is a metal polish paste) .. i'll be posting the end-result in a second

nothing short of amazing ..
following the 1200 grit, the crystal should be a milky white, and at this point it is easy to see where there are deaper gouges and a bit more rubbing needs to be done.
These are plastic crystals (as someone in another thread kindly informed me) and they really don't take that much elbow grease ..
give it a try

nothing to lose!
