Second Hour Beacon 2 Field Watch — Full Lume, DLC Case

Owners widely praise the Second Hour Beacon 2 Field Watch — Full Lume, DLC Case for its attractive, out-of-the-ordinary colorways, good machining tolerances, and a great bracelet and clasp. The full lume dial is a point of varied opinion; some find it bright and long-lasting, readable well into the early morning hours, while others note it fades quickly, becoming illegible after a couple of hours, though still faintly glowing. The DLC case's subtle color difference is appreciated, though the lack of a curved case to match the bracelet is noted. Overall, owners rate the Second Hour Beacon 2 Field Watch — Full Lume, DLC Case highly for its distinctive full lume dial and well-executed case and bracelet finishing.
