Welllll, at least Roland has confirmed what I thought, i.e., that the Eta cal. 1081 is the same as the cal. 1080, but the 1081 is the larger one (11-1/2 lignes). Unfortunately, Richie's watch doesn't look exactly like the 1080 or 1081 watches that Roland pictured, but that's because different style bridges were used, as Roland points out.
I see that in my last post (above), in my second reference to Richie's 671, I inverted the 6 into a 9 and made it into a 971. That's unfortunate because there is already enough confusion surrounding the Hamilton grade 971. The grade 971 was originally a 16-size, 21-jewel, pendant-set, hunting case movement.
Many years later the grade number 971, unbeknownst to the folks at Hamilton (U.S.A.) in Lancaster, PA, was applied by the folks at the Hamilton-owned Buren Watch Co. factory in Switzerland to Hamilton-marked, 16-size (19-ligne), 23-jewel, lever-set, open-face watches being supplied by Buren to H. Steele in Mexico for use as standard watches on the Mexican railroads. Eventually the Swiss Buren Hamilton 23-jewel grade 971 caused some confusion and, no doubt, consternation at Hamilton (U.S.A.), especially in the materials department, until things got sorted out. 'Nuff said on that!
If you are unfortunate enough to re-read my last post (above), when you get to my erroneous reference to 971, please change the 9 back into a 6 in your mind to avoid any confusion or consternation here. <];>)
Thankyouverymuch!
