This is a Bulova Ladies watch in 14K White Gold with twenty-two (22) Diamonds. The movement is stamped with: N2 Date Code, however the outside case is stamped: N7. The case inside markings are: 14K GOLD, L & W, M290, 104925. The case outside markings are: 14K GOLD, BULOVA, N7
Some checking through the ads has not uncovered any matches. The date difference between the N7 case and N2 movement is a bit much at five years. However, the case #M290 does call for the 5BD movement, which I think came in either 21 or the more common 23 jewel. What is odd is that this case number is not listed in the 1974 case book, but here is using a 1972 movement. I found it listed in the 1979 supplement book; and interestingly it states that is uses a sapphire crystal, which would seem a luxury component in line with such a high-end and expensive watch. What I would expect to see with a 23 jewel movement is the '23' on the dial. I have found a 1977 ad for a lady's 23 jewel watch with 23 on the dial, and also a 1977 La Petite ad with no 23 on the dial (though no mention of jewel count in the description, but that model had always used a 23...right?), and a 1974 ad for 23 jewels showing both with and without 23 on the dial. Seems some models had it and some did not.
I am feeling as though the watch is correct, and perhaps the movement has just been replaced at some point.
1977 Unknown.
I agree with Ken, 1977 Unknown. Very likely a movt replacement.
This is an interesting piece, late in the quartz crisis, yet still top quality and possibly a sapphire crystal to boot. A jeweller will be able to confirm the crystal.
Still, a breathtaking watch by any standard.
