My Navihawk died after about a dozen years of satisfactory service. As I discovered the hard way, breaking the case seal of the Navihawk to replace the battery (which was necessary three times over it's lifetime) created a pathway for humidity and skin oils to penetrate and corrode the interior. (This despite the fact that I never swam nor showered while wearing the Navihawk.) The cost to repair my Navihawk was almost as much as the purchase price of a new Skyhawk.

I compared the JR3000-51F with the titanium version...&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Citizen-Men-s-Eco-Drive-Titanium-Skyhawk-Chronograph-Watch-JR3060-59F/dp/B0007OER0S/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Citizen Men's Eco-Drive Titanium Skyhawk Chronograph Watch #JR3060-59F</a>...as well as the model that synchronizes with an atomic clock signal...<a data-hook="product-link-linked" class="a-link-normal" href="/Citizen-Men-s-Eco-Drive-Skyhawk-A-T-Watch-JY0000-53E/dp/B000ZPMYQI/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Citizen Men's Eco-Drive Skyhawk A-T Watch #JY0000-53E</a>. Having been accustomed to the weight of a stainless case and bracelet, I didn't think that the titanium version offered me much added value for the price differential, particularly since some other reviewers had noted that the titanium model was susceptible to scratches. I came to a similar conclusion regarding the "AT" model. My experience with the very accurate time-keeping qualities of the Navihawk led me to believe that the JR3000-51F would satisfactorily meet my needs. The "Eco-Drive" feature clinched my decision to purchase the Skyhawk as opposed to competitors.

Upon receipt of my Skyhawk (which arrived earlier than the projected delivery date), it worked right out of the box. The time was off by a couple of minutes, but the interactive instructions (on the CD in the box) made it a snap to correct the time. My prior experience with the somewhat idiosyncratic process of adjusting the Navihawk probably helped me get off to smooth start with the Skyhawk. Count me as a happy camper.
