As one of its daily deals, A4C offers the refurbished Apple Watch Series 1 Aluminum Sport Smartwatch in Space Gray for $139.95 with free shipping. That's $17 under last month's refurb mention and the lowest price we've seen in any condition. (It's $39 less than the best deal for a new unit today.) It features an aluminum case, Ion-X glass display, heart rate sensor, accelerometer, gyroscope, microphone, speaker, 802.11n wireless, and Bluetooth 4.0. Deal ends today.

Note: A 90-day A4C warranty is included.
