A very nice watch, although I think that the main picture is a bit deformed due to the close up and the kind of lens used to make the picture. The history on this watch: I call it the "Clock" shape after the shape of the clock of my grand parents standing on the radio. The shape started life as the 6720 in 1922. It was advertized only as 18K and gold filled, so never in 14K. In the first ad with names from the Corsacana Daily Sun in Texas of December 1924, this shape gets the name Norma. Interestingly, this ad is for the gold filled version and you see immediately a difference with ad that shows the solid gold version. The later has laurel leaves engraving on the bezel all around. The gold filled version has a 4 flowers sitting at East-South-West-North. A deliberate act to show difference between solid gold and gold filled cases? The case signature is used in both 1924 and 1925 gold filled watches. After that (1926) it changed, adding the patent date and also the American Standard name came back. The movement is from 1925, a 6N. During 1924 and 1925, Bulova had a whole range of movements with 16 jewels that were never advertized: the 6E, 6M, 6N, 6R and 6W. Only the 6P and 6PP had 15 jewels. For what I have seen, the split of watches with oval movements of that year were 40% the 15 jewel 6P or 6PP and 60% one of the above 16 jewel movements. The 16 case number I find with both 1924 and 1925 movements. The 16 was the last series of numbers starting with "1" before the new system with the first digit being the year came into effect. Since some cases exist starting with "4", and the second digit always a "0", this must have happened towards the end of 1924. Hence you see these 16 numbered cases with both 1924 or 1925 movements. Nice detail: see the side engraving of this watch. It is with this triangular flower motive. This is quite unique since this shape never had this kind of side engraving. It normally has some curly branches with leaves engraved on the side. All in all, conclusion is that this watch is a very early 1925 clock shaped watch and therefore I vote for: Norma.
