Walmart offers the Armitron Men's Multi-Functional Digital Sports Watch, model no. 408231RDGY, for $16.79. (Target and Amazon have it for the same price.) Opt for in-store pickup to avoid the $5.97 shipping charge. That's the lowest price we could find by $6, outside the below offer. It features a resin case and band, Japanese quartz movement, date display, and water resistance to 330 feet.
Considering buying more than one? At Target, add two to your cart and the price drops to $25.18 with free shipping, which works out to $12.59 per watch.
