I was dreaming about the aquanaut recently after meeting an eminent patek collector, and also seeing a fellow purist posting in the forums about the aquanaut. It led me to check out patek's website to ogle at this beauty. However, what hit me was not the looks, but rather, the specs. (pic and specs taken from patek website)
If you notice, the dimensions of 40mm is exactly for most wrists. But the best thing about it is the 8.1mm thickness. I've always looked to pateks as thin elegant pieces, but it never dawned upon me that the aquanaut is so thin. And to top it off, the water resistance is 120m. This is much a good couple of mm less than a sub, and also slimmer than the Panerai due with substantially more water resistance. Check out the side profile. (pic taken from patek website)
While many lament the finishing on some pateks, one thing they do not forget is the profile and the slimness. It reminds me also of the comparisons between the 5170 and the dato. The 5170 was superb in terms of the thickness (or slimness) which was a good amount slimmer than the dato. Very very amazed. Sometimes it's interesting when you view things over and over and get new revelations.
