Gary E. FosterHamilton 990 dial question
Anyone know if a Roman numeral dial would be correct for a 990

Bila WirriganwaltersDepends what serial number for date of production Gary, they were making 990 Grade as early as 1903 I think.
So if it is that early there would be no reason it could not have a roman numeral dial on it to my knowledge. Would need a serial number to shorten the odds a bit to be more positive.
Someone with a bit more knowledge on Hamilton's might be able to enlighten you more.

Harry J. Hyaduck Sr.Bila may be right but to my knowledge a Hamilton 990 was RRG and RRA so I think it would have been required to have a Arabic numbered dial buy the RR's.

Gary E. FosterThanks guys, watch is currently in safety deposit box, I'll have to get it out, although I suspect the dial has been replaced

Claude GriffithTo my knowledge based on looking at ads and sales catalogs nearly all companies in the late 1800's and early 1900's offered a diverse selection of dials for the user to select from, some with no extra cost and some at extra cost. Just because a watch is RRG or RRA does not mean that it was used for rail service nor that the owner was compelled to put an Arabic numeral dial on it. I honestly think few watches are original because previous owners probably made changes to fit into their likes or interpretation on what "correct" was or is. If I see a nice grade 214 with a beautiful glass dial on it, I won't get upset or tell the owner it isn't correct because I know at the time of the 214 production glass dials were offered by Elgin at extra cost. As the wristwatch became more popular these dial offerings ceased, so if I see a Elgin 571 or a Hamilton 992B with a Roman numeral dial then I can definitely say it is incorrect because it was not offered by the company. In the time frame mentioned some people preferred the Roman numeral look because that is what most clocks used. I think in the future you will see a lot of 992Bs with incorrect enamel dials on them because the melamine dials are falling apart at a rapid rate.
In the case of my lever set grade 150 it has a Roman numeral dial on it and it is RRG and RRA but the dial has red 5 min markers and was offered by Elgin as an option when the watch was produced. BTW the 990 is a beautiful movement I have several and got them at good prices because some collectors will pass them over for the 992 which is strange because the 990 is a better movement than the 992.
