Time(x) has sure improved these.  I had a couple about ten years ago when they came out (no vibrating alarm) and this is much more solid and accurate.  I don't know what the case is made of (the back is stainless), but it's much more substantial than the original die cast (pot metal) ones, and the parts are heavier and made to closer tolerances.  The super-quick-setting under-an-hour alarm is still brilliant, and the 12-hour alarm is quick and accurate as well.  The hands, even the second hand, are fluorescent even though the watch has Indiglo so bright you can use it as a flashlight in certain situations!  When the alarm's not set I use the under-an-hour red alarm indicator as a day indicator, 12 o'clock for Sunday, 1 o'clock for Monday, etc.  Also, you can set it to the minute to note elapsed time or set the 12-hour alarm to the present time for longer elapsed time (parking).  A snug strap adjustment is better for feeling the alarm.  (This watch is vibrate only; Timex makes at least one with the same features but with an audible-only alarm).  When I got this watch I set it repeatedly for a few minutes ahead to get used to it.  It wakes me up just fine, and rather pleasantly, and I have yet to accidentally turn off the alarm set.  Pay five to seven times as much for a Bulova and (some models) will allow choosing between audible and  vibrate alarms, but will only be accurate within 12 minutes (one minute for an hour-only alarm hand).  Pay five to seven times as much for a Citizen Calibre 8700 with a hard-to read day indicator and an excruciatingly slow motor-driven 24 hour alarm set (or check!).  Two time zones?  I'll reset the Timex if I travel.  Perpetual date?  The Timex has forward and backward quick-set date.  Eco-drive?  So I'll buy a battery every few years.  And the Citizen weighs MORE and doesn't vibrate.  Oh--and do you really need a chronometer (stopwatch) as some complicated alarm watches (with three small dials on the face) have?  If your kid's on the swim team surely you already have a $15 digital split timer.  For analog people who want a super quick-setting (vibrating) alarm, especially an under-an-hour one for naps or not to forget you're draining excess water from your pool or you're supposed to call your mother-in-law (ouch), this is a solid, inexpensive, brilliant watch full of useful features.
