Al, please clarify that Omega had the same part number for the "strand" links even though they had different tapers (18mm for 1998, 16mm for 1499/1498) and link pieces (4 for 1998, 5/4 for 1499/1498). I know Omega has repeated serial numbers for straps every once in a while, but did they also do so with bracelets?
Also, I misspoke before as the 1498/1499 bracelets had "strands" of both 4 and 5 links attached, sometimes on the same bracelet (as can be seen here from an earlier FS post):
