The back of my watch says 'waterproof' and 'dustproof', and it also has serial numbers 793 A. The clasp is marked SPIEDEL USA, 1/40 10k RGP TOPS, 1/50 10k RGP ENDS & CTR.īenrus Watch - Approximate. The band is made of a delicate gold mesh. The back is marked Benrus, 20 micron gold, electroplate bezel, 10k R.G.P. There are no numbers indicating the hour. It is labeled BENRUS and 21 jewels on the face. I love this watch! I don't know anything about it except I got it in a box of jewelry when my grandmother passed away.
