The melamine dial is not done in 3 pieces as your enamel one is. The three-piece enamel dial has the centre disc and the seconds bit soldered on from behind, using bismuth solder which has a very low melting point. Melamine is a resin that will not stand heat, so those dials are made in one piece! Also, the detail at the edges of the two applied discs on the enamel dial is much crisper than is the case with melamine. Plus, the melamine has (in gemological parlance), a waxy lustre, while the enamel dial has a vitreous lustre. I have never seen a melamine dial that is as white as the enamel dial.

I'm going to respectfully disagree with Doug. This is a No. 121 Melamine. If you see "chopped" corners on the "0" (10 o'clock) and a few of the other numerals, like the "8") it is a Melamine. This movement was made in 1948 which would place it at and near the beginning of the use of Melamine dials.

I don't have a vast amount of experience with Melamine dials, but I've owned a few. The sinks on that dial look much sharper than any melamine dial I've seen. It certainly looks like an enamel dial to me.

Here's a photo I had handy of a melamine dial, for comparison.

Another "pointer", the 5-minute markers on the enamel dial are square, whereas on the Melamine they are rectangle.

I would need to see that dial in my hands before I would be convinced it is not enamel. Even though evidence might seem to indicate it is melamine. If it proves to be melamine, it is by far the nicest melamine dial I have ever seen. My understanding is that enamel was phased out circa 1949, but this serial number appears​ to me to be earlier than that. Before I replied to this post, I checked my own Hamiltons, and I have a 992E with what I contend is the same dial, and it is double-sunk vitreous enamel!

The easy way to spot a melamine dial is to look at the edge of the dial. You can usually see enough of the edge without taking the movement out of the case. The edge of a melamine dial just under the white top surface will be black. The enamel dial will be white.

I think Robert may be right about this one although it may be one of the nicest Melamine dials left in existence if he is.

many thanks to everyone for the info,looking through a loupe the dial still looks like 3 separate parts the edge of the dial is white.and the numbers look like raised enamel,not as in printed flat,on the surface.Hope this help clear any points.if it is not an enamel dial it is nice to know that it may be one of the only perfect melamine dials in existance

do you have the skills/tools/ability to remove the dial?
if so, a view of the back side will be conclusive...or more so than the front

'in hand' these can immediately be detected... image variation with lighting, reflections, etc skew things.

If you look carefully, you will note that the numbers 5 and 7 go past the edge of and into the "sink" . That wouldn't be the case on an enamel dial where the recess for the seconds bit is ground out, removing the edge of the numeration.

I have a 1951' 992B ,,dial that appears to have a "slight tint to it" ,,any thoughts?? (it is not the lens/crystal ,this picture does not show the tint to well)
Also I believe this is an ENAMAL dial by looking at it ,,without taking the movement out,,any thoughts on it??
Thanks So Much,,,Eric

Respectfully,,,After giving the numbers a Good look through a loop,,,I do not see the numbers falling into or past the "sink":???: This has me puzzled.
Any idea on the slight "TINT" the dial has? You cannot see it in this photo, but trust me, next to a white enamel dial it is obviously a TINT.
Has anyone ever noticed a tinted dial ?? I have 3 other 992Bs and a 1924' 992 Blind man dial, all have bright white faces.
I really Appreciate the info and consideration on this issue,, Thanks in Advance,,,E

Melamine can discolor.

Take the front bezel off and see if the dial is shiny.
