Ok, So I got a 16 size Keystone Howard that I believe is RR model. I have someone that disagrees with my observations but I do understand that they do not have the watch in their hands and they have not torn the watch down to service it. SO, The purpose of this thread is to get more information and to Let all the EXPERTS on here see what I have going on here. I believe this is a 16 size Lever set Series 4 Keystone Howard RR Grade Watch. I will now list pictures and supporting evidence. Notice that the Balance wheel has solid gold screws. All of them are gold. Now, Notice that the Hairspring stud is Rounded, Just like a most series 10 and ALL Series 11. This is specific only to the RR grade watches Howard made. Also notice the upper balance wheel jewel is screwed in from the bottom, just like most series 10 and ALL series 11, Again another flag of RR Feature on this watch. Also, when the balance cock and wheel is removed, notice how the plate is frosted and does not have a Damaskeen pattern. Just like series 10 and All series11 . Almost all series 9 have a circular damaskeen pattern on the plate side facing gears. Mine doesn't. Also, I have the updated white train wheels. I believe mine is probably the absolute most high grade, Top of the line at the time, Newest at the time, Absolute most superior 17 jewel 16 Size Keystone Howard probably ever made. This one has all the features of the newest keystone Howard watch features of the time. This one is probably the top Number 1 Highest grade top end 17 jewel keystone Howard in existence. Yes I believe its adjusted 5 positions too. Im not going to show the front of the watch or the dial. We all know what RR dials look like and this one doesn't have one on it. Its not in a Howard Case either. Somewhere down the line, some idiot took all that stuff off this watch and what I got was a movement. They didn't know any better. Its mine now and I know what it is. SO does anyone disagree with my assessment on this watch? This watch is not supposed to exist. This should be a series 9 based on the serial # but it is not. Any one have any imput on this topic would be greatly appreciated. Thank you for your time. IN this first picture notice the frosty plate where the balance wheel is removed. Series 9 have a circular damaskeen pattern like the last picture I have posted in this thread. Notice the Serial # Match the watch movement. Solid Gold Balance wheel screws also. Notice the rounded top of the hairspring Stud. Only the RR watches have this during this time period. Again. notice my Upper balance cock jewel is screwed on from the bottom, I also have a white Train. Notice the Circular damaskeen pattern on the plate under the balance cock of the series 9 parts movement picture below. My Series 4 is frosty with no patterns. Any more information would be greatly appreciated. We see this is going on to the end of the production serial # for my watch. It may be 1 of a kind. Thanks.
