Here��s why the price increase won��t change demand for 5711 & 5712
Prior to the price increase, the 5711A and 5712A were the two least expensive watches in the Nautilus line. After the price increase... they still are.Although the Aquanaut is a fine watch and has a loyal following, it is a very different watch than a Nautilus. Very few people are going to get a 5167 or 5164 over either the 5711 or 5712 because of the price increase. I find it hard to believe that people favored a 5712 over a 5164 just because it was $2,000 cheaper before, but won't now that it is $4,000 more. For a watch in the $33,000 - $39,000 range, people are going to buy what they like (or can get), not which one saves them a few thousand dollars.For the 5711, which watch would you prefer over it for $29,000 that you didn't prefer over it for $24,000?
