No matter the personality of your guy -- sports fan, academic, backpacker, businessman, or all of the above -- he'll appreciate a watch for Fathers Day; after all, who doesn't need to know what time it is? (Or as the NY Yankee manager Casey Stengel once allegedly said when asked what time it was -- "You mean now?").
There's a huge range of watches available for Fathers Day -- here is a sampling:
An everyday watch that will easily pass muster at a business meeting, the Fossil Tan Chronograph ($115); this stainless steel, analog, quartz movement timepiece is fitted with a calfskin leather band with stud accents. It features a full range of individual timers -- second, minute, hour -- plus a tachometer ring. Water-resistant to 100 meters, this watch has an 11 year (limited) warranty.
A rugged watch for your athlete or traveler (it features three time zone readouts), this Timex Ironman Triathlon 30 Lap Watch (was $50; now on sale for $34). The watch sports daily, weekday, and weekend alarm settings, day/date/month windows, and a Velcro strap for easy donning and doffing; I own a Timex like this one, and I like it because it's easy to remove when I'm working where it might be susceptible to damage.
The Nixon 42-20 Gold Chronograph ($500 plus free shipping plus 110% return) features a trio of timers, and a date dial, included in the over-sized, scratch-resistant Hardlex mineral crystal case; this timepiece is right at home in the office, and rugged enough for the dive boat. 200 meter water-resistance and a fold-over wrist clasp with a double push-button safety means this guy will stick with you for a long time. Any father who receives this nice watch on his special day won't soon forget the thoughtfulness of the giver.
