Amazon offers the Armitron Men's Sport Digital Chronograph Watch in Black, model no. 40/8254BLK, for $15.73. (Walmart sells it for the same price with in-store pickup.) Plus, Prime members bag free shipping. (Non-Prime members can spend $35 or more to qualify for free shipping; otherwise, shipping adds $4.48.) That's the lowest total price we could find by $41. It features a resin case and band, digital display, quartz movement, and water resistance to 330 feet.
