The Digital Guy via eBay offers the Pebble Steel Smartwatch for iOS and Android, model no. 401SLR, for $42.99 with free shipping. That's $5 under our January mention and the best price we've seen. (It's a low now by $16.) It features a stainless steel case, leather strap, and water resistance up to 165 feet. It connects to compatible iOS and Android devices via Bluetooth and allows you to manage music, play games, check scores, read texts, and receive notifications and incoming call alerts.
