A slide rule I will never use
By Kenji Watanabe, Osaka ยท
I learned to use a slide rule from my father, who used one at a Kansai electronics firm before calculators took over. I can still do it. I still would not do it on a watch bezel while standing on a crowded train.
The Navihawk A-T is a bigger, more aviation-obsessed version of the Skyhawk idea: 48 mm by 13.5 mm, steel bracelet, caliber U600 with radio sync, world time and chronograph, and that circular slide rule. It is built well and the Eco-Drive is as dependable as Citizen always is.
But 48 mm is simply too big for most wrists, including mine, and on the steel bracelet it is heavy. Mineral crystal again. 695 to 795 dollars. I think it suits big wrists, pilot enthusiasts, and people who like their wrist to resemble an instrument panel. Everyone else should try it on before buying, preferably at the end of a hot day when wrists swell a little.
