Hamilton 990? Gelson shows it's a 900 (FOUND)

Michael P. McNameeHamilton 990? Gelson shows it's a 900 (FOUND)
Hi all.
I saw this Hamilton movement on Ebay and it was so spectacular looking I just had to buy it (for $158). The seller advertised it as a 990, and it looks like it is based on my research on this site. However, it is unmarked, and the Gelson list shows the serial number of 342297 as part of a 1905-1906 run of 12-size Model 900s. Anyone have any thoughts about this apparent anomaly? Also, anyone have a correct DS Hamilton 4-footed dial they'd be willing to part with?

Buster BeckThat is a "typo" and those serial numbers should be for 16 sz. 21J Grade "990's".
The first 12sz Grade 900's weren't produced until 1910. They are 19J bridge model watches with a checkerboard/fishscale/jeweled style of damaskeening. But be careful about buying a 900 movement by itself as they are hard to find a case that will fit them as they require a slightly larger than standard 12 sz case.

Michael P. McNameeThanks Buster. Was it common for 990s of this era to be unmarked?
September 10, 2014, 22:43
Harry J. Hyaduck Sr.The 990 is much more collectible than it's counter part the 992. For every 990 you see you will see at least 50 992's. Yes it is very common for the 990's to be unmarked. I have two 990's. One is marked the other is unmarked. The 970 looks just like the 990 but it has the positive set winding stem. Very nice!

Michael P. McNameeThanks Harry! I just love the look of this movement. For fun I ran a search on Ebay for 990s, and I think only three or four complete watches came up.
September 10, 2014, 22:53
Michael P. McNameeBTW, Harry, what is a "positive set winding stem."
September 10, 2014, 23:10
Robert McClellandThat is definitely a very nice 990. The Hamilton ledger pages and the finishing records and othe lists all show it as a 990. Gelson's date is OK 1905-06 so it looks like just a typo in Gelson.
September 10, 2014, 23:12
Harry J. Hyaduck Sr.That is what Hamilton used on their early pendant set size 16 movements. There is a tiny screw just below and off the side a little below the winding stem. You back off on the screw to pull the winding stem up to set the watch. Then you tighten the screw back down to positively lock the winding stem in place so that it can not accidentally be pulled up when you take it out of your pocket. You have to have the correct type of winding stem to use on of these type Hamilton's. Waltham used the same system on there model 1888.
I got lucky on my marked 990 I paid $170 for it and it has the correct DS dial AND it is in a Hamilton marked display case.

Michael P. McNameeThanks Robert and Harry. Harry, it sounds like you got a terrific deal on your marked 990. I already have a non-Hamilton high-pendant CWCC case that I think will be great for this movement. Just need a dial, but this time (for once) I went into the transaction knowing that Hamilton 4-post dials are not all that common but that they can be had from time to time.
September 10, 2014, 23:52
Harry J. Hyaduck Sr.Michael I have several DS 4 post dials. I have seen them go for big bucks. I do have some chip free hairline free dials but since I am not crazy to want to get rid of them I would take $85. However I do have a couple with hairlines I would let go for $45. Nice looking dials that should soak out pretty nicely. I also have a Swiss repo 4 footed Montgomery dial which is one of the nicer Swiss reproduction dials I've seen an it would be $55. Personally if I had the money I would go for the Hamilton dial. If you want to hold off and see if anyone else offers you a better deal that would make us both happy.
Here is a couple of pictures of my 970 with positive set.

Harry J. Hyaduck Sr.Blurry but you get the picture.
September 11, 2014, 00:12
Michael P. McNameeHarry, I'd be happy to pay the $85 for an era-correct, problem-free DS Hamilton dial. Could you shoot me some pics to my email address? Look forward to hearing from you.
September 11, 2014, 00:15
Michael P. McNameePS, that 970 is a great-looking movement! Were all 970s pendant-set?
September 11, 2014, 00:47
Harry J. Hyaduck Sr.Hi Michael,
Let's let the guy's that sell dials see this first. They love to sell their dials. So lets give them a chance. They my be a little cheaper and even if they are the same price they would love to sell you the dial. I would sell you one but I really only want to if they don't have one. Besides after putting on my opti-viser and magnifying them about five times I see only one of mine is perfect. The others have very fine hairlines as seen through magnification. I guess that is true though with a lot of dials that are eye clean when you magnify them you can see fine hairlines. I'll keep an eye on here. I know Rob, Phil, Jon and Larry all sell dials. Lets give them a chance first.
Harry
September 11, 2014, 00:48
Harry J. Hyaduck Sr.Yes all the 970's were pendant set and all the 990's were lever set to my knowledge.

Paul D. TrombleyMike,
I picked up a 4 foot dial by buying an early 974 parts watch... I had a 990 that needed a set lever and a dial... the 974 came at a price less than buying a loose dial and gave me parts to fix several watches.
The 974 and 990 share the same patent dated plates and most of the parts cross over.
September 11, 2014, 12:02
Michael P. McNameeSounds like a plan, Harry. I've been watching Larry's dial auctions, but currently he does not have any Hamilton four-footers. But I'd love to hear from anyone who would be willing to sell one. And thanks for the tip on the 974, Paul--that's a great idea! I'll check Ebay to see if an appropriate 974 is available.
Also, I recently wrote a post on a pristine Huguenin "Rail Way Time Keeper" dial that I picked up over Labor Day. If anyone has any interest in a partial trade I'd be all ears. Otherwise I'm happy to pay all cash. I'll wiat to see if anyone responds.

Harry J. Hyaduck Sr.Hi Michael,
Paul has given you some great advice. However if you don't want to wait I do have the really nice one for $85 I also have a really nice one that has just the beginning of a hairline at the 2 position for $65 and the ones I mention before with more hairlines at $45. Shipping would be $3 for any of them. I will send some pictures later.

Buster BeckPlease keep in mind that the dial for the Grade 990 should be a double sunk dial as that's what all the advertising from the day mates them with. The lesser grades that weren't RRA/RRG such as the 974 etc. came with only the seconds sunk dials.
regards,

Michael P. McNameeThat sounds fine, Harry. I'll look forward to seeing the photos.
September 11, 2014, 14:47
Michael P. McNameeAnd once I get the dial I'll post a photo of the complete watch in this post for review and comment

September 11, 2014, 15:53
Harry J. Hyaduck Sr.Michael this is what the dial should look like. I will email you the pictures as you requested.

Donald TrumbleSome points you may find of interest:
Production figures as shown on pages 51/52 of the Ehrhardt Hamilton Book (compiled in 1976 and revised in 1981) shows there were around 16,000 of the 990 all of them Lever-Set (CORRECTION OF MY PREVIOUS TYPING ERROR) produced between 1903 and 1919 when the model was phased out of production.
Compare that with the fact more than 540,000 of the 992 were produced. And speaking of rare watches, the Hunter version of the 990 the Grade 991 which also was Railroad Approved at the time of production, only about 2,500 of those were produced.
About Grade Markings, the reason for the lack of grade marking on Harry's watch is the fact grades were not required to be marked on watch movements entering Railroad Time Service until a 1906 change in the basic rules.
On the subject of dials, what Buster Beck posted above bears repeating and committing to memory:
"Please keep in mind that the dial for the Grade 990 should be a double sunk dial as that's what all the advertising from the day mates them with. The lesser grades that weren't RRA/RRG such as the 974 etc. came with only the seconds sunk dials."
Hamilton was very specific about their dials and as collectors we should do all we can to preserve correct examples. These watches will be around long after all of us are gone.

Ralph HopperHi Guys, another very interesting discussion here. Could I get something clarified please?
The info posted above relating to the OP movement by Hubert shows 'lever set' while what Don has just posted it says 'all Pendant-set'.
I have a 990 just a bit earlier in number from the OP one and it is lever set also.
Thanks
September 12, 2014, 13:05
Harry J. Hyaduck Sr.To my knowledge all 990's are lever set I know both of mine are. All 970's are pendant set to the best of my knowledge as my 970 is positive pendant set. I don't know if all 970's are positive set but I suspect they are.
Harry
September 12, 2014, 13:37
Ralph HopperThat is what I thought about the 990, Harry, since that was the info that I had previously. I'm guessing that Don just mis-typed the phrase but it's always good to check.
September 12, 2014, 14:34
Harry J. Hyaduck Sr.I agree Ralph.
September 13, 2014, 12:10
Michael P. McNameeThanks for the very informative post, Don. I guess my non-marked watch must have been manufactured just prior to implementation of the 1906 change.
I've struck a deal with Harry for the DS dial that Lindell and Buster have also indicated in previous posts is right for the 990. I'll post the compete watch early next week once I've installed Harry's dial.
September 14, 2014, 17:21
Donald TrumbleThanks to you guys for catching my typing error.

Of course all the Hamilton 990 were in fact
Lever-Set, thanks much! That typing error is now corrected.

And I have re-checked the rest of my post for accuracy.
Here is some
additional Grade 990 information well worth reading.
Don
In that linked topic Lindell's Hamilton 990 movement number 374629 is marked:
September 15, 2014, 21:08
Michael P. McNameeWell, here it is. Harry, your $65 dial is superb--no flaws of any kind that I can see with or without a loupe. Hands are terrific, too. My thanks to everyone who commented on this post. This is the first Hamilton non-992 in my collection.
September 15, 2014, 21:22
Harry J. Hyaduck Sr.WOW it's a looker! Glad I could help you out Michael. Now I had better not see it on eBay. LOL I may just be too critical but there is a tiny short hairline at the 1 1/2 minute mark. Enjoy!
September 15, 2014, 21:28
Michael P. McNameeThanks Harry! FYI, I have never listed a watch or anything watch-related on Ebay. I am a collector. That's not to say I never will list a watch if I have a duplicate or an unneeded part, or if financial conditions at some point require it. Hopefully not anytime soon
