I have been doing some digging again on a movement. In this case it is the of bridge 21 jewel style 6. I have gone through the Bulletin and read the 2 articles that Howard Lasser did as well as the ledger entries and the 2003 RR Corner done by Uberall and Singer. So at least I am not starting at nothing on this watch. Amazing research done by all. The watch is the one below. Dial appears to be correct for the time frame. I am betting on a 4 foot dial. I am also betting on it being original and you will see why later. The case is most likely a later one used after the original may have been melted. The movement is the style 6 thin. There was a 19j, according to the articles, that was a sample but all others were 21j pendant set. As you see by the pic it has the detent screw for the stem. I also believe this means that it has the larger dial plate than the later 16s movements. I will have to see if that is mentioned anywhere. The serial is where I had a bit of an issue. 175622. The movement is obviously dirty and needs a clean. That can also be seen by the dirt on the dial. So why would the dial be an original on a HWW watch? I think it comes to the ledgers. When you look up the 175622 serial you get the blank pages. https://nawcc.org/images/stories/Hamilton/LedgerPages/100001-200000/175601-175651A.pdf That got me to looking at the 2nd Lasser article. The movement listed with the HWWCo markings that is a style 6 has the serial of 75616. If you drop the 1 on mine you get 75622 which is only 7 away from the exact same model movement. SO back to digging in the ledgers and finding out the indexing was off some I found this.... https://nawcc.org/images/stories/Hamilton/LedgerPages/1-100000/75606.pdf When you look down the page you see that the information on the 75616 is accurate as being sold to Burr W Freer. At 75618 you find that Wheeler is the name listed for the rest of the page. The top of the page indicates all are 21j. When you get to 75622 you find something odd. The line is noted with bought and sold for that watch being 8/20/00 and 8/21/00. But just above you get the note of that serial with 175622 and the dates 7/18/01. I don't get why they felt the need to note that the movement was 21j being the page already noted that. It does state Bridge and OF though as well. There is a note in the Dec 2003 RR Corner that the Circular pattern ended with this serial as 75623 had the wavy pattern. This same irregularity happens for 75624/175624, 75626/175626, and 75628/175628. Sold and returned? Sent back for engraving changes? So far I have only seen this for these 4 serials in this range. So does anyone have a reason why Lasser said that there were 5 made and only 1 surviving? Was this different than the group of 4 that I listed plus the 75616?
