With all the talk of Hamilton 940 PW's the last couple of pages one came up in my auction watchlist that my wife had added without my knowing but luckily (or not) I spotted it a couple of hours before the auction was due to close, pure luck as I haven't been watching many auctions much with health issues taking my attention away from the very pleasurable activity of watch collecting and in this case Railroad Grade Pocket Watches.
Long story short many others wanted it too as these are a rare item here in NZ ( US RR ) but in the end I snared it at a reasonable price given it is not in working order currently.
I've stated here before that I am not a huge fan of Faux train imagery on PW's but of course this IS a RR Grade without doubt and its very well used casing probably means very much a work watch even though in a Sterling Silver case.
Serial number 526944
Haven't yet got it in my hands yet so unfortunately just the sellers poor pics.
