Amazon offers its Prime members the Casio Men's Digital Sports Watch
, model no. AE1000W-1BVCF, for $16.54
with free shipping
. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $4.48.) That's tied with our mention from last month when we saw it for pickup and $5 under the lowest total price we could find elsewhere. It features a black resin band and case, quartz movement, world map time zone display, and water resistance to 330 feet.
