Sea King from me. This is a good example model to check in the Bulova Price Lists. It may not be the subject watch, but two Sea King variants are listed in the 1954 Novemeber Supplement. I have been operating on these supplements indicating both newly released models/variants AND/OR changes in prices to previously existing/released model variants.
1954 Novemeber Supplement
Then take a look at the January 1955 quarterly price list- in what I've been calling the "newly released" section. Again we see the Sea King "B" 167 listed.
This highlights bobbee's suggestion that we cannot be to rigid in production/release years based on things like price list without understand the lists better, and in light of all other documents/ads.
Did Bulova simply forget to take the 167 Y Sea King "B" record out of this Jan 1955 "new" section? We don't know.
Was there a new change in price of 167 Y Sea King "B" in Jan 1955 compared to Nov 1954? I don't see any change of price from November 1954 supplement.
The Sea King B 167 could not have been newly released in both November 1954 and January 1955.
When we look at the January 1955 "Cumulative Model Price List" section, we see five "variants" (I'm calling the examples without a variant letter assigned a variant- the variant being no variant letter).
Jan 1955 Cumulative Section
Bobbee is correct in saying "we can't be too ridgig". Without all the price lists, it's difficult to say for sure what is "newly released" in a price list, and what model/variant previously released had a new "Price Change" showing up in the "new models" section of said price list.
Confirming Model and Variant based on the 1957 Linebook BAWD0132
1953 Sea King "B". Note that the Linebook shows the Sea King "A" as having a black dial. Also not the sales books show two listings for Sea King B. One for $57.50 and one for $59.50. I wonder if the extra $2 is for an expansion bracelet.
