·All in jest of course as at that time all of the major US PW makers (some european too) were doing similar cases with etched Silver dials just the similarity and the later takeover of Illinois struck a chord.
My example dates to 1927 regardless of the inscription and Hamilton purchased Illinois WC in 1928 though they still continued making Illinois watches and continued the brand name for some time after.
PS the only Hamilton WW's I am ever likely to buy are those that predate the Swiss takeover of Hamilton, and to that end is the one on the left a US made or a later Swiss?
