# Best automatic field watches Source: https://lumeandbezel.com/best/best-field-watches Publisher: Lume & Bezel. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://lumeandbezel.com/how-we-pick A field watch has one job: tell the time at a glance and survive daily wear without fuss. That means a legible dial with large numerals and lume, a light case in the 36 to 42 mm range, and enough water resistance that rain or a swim is not a worry. The real differences between models are in the movement, the power reserve and the crystal. This guide compares eight automatic field watches, from the Seiko 5 Sports field models to the Hamilton Khaki Field and two Bulova military pieces. Each is judged on the case size, movement, reserve, water resistance and crystal its listing states, and gaps are marked Not stated so you can check them first. ## Picks ### 1.
