There’s also a neat trick where holding the 4 o’clock pusher switches off the negative digital display and leaves the analog hands to tell the time alone. The resin case wears a steel bezel, carries 100 meters of water resistance, and weighs under 57 grams. The catch is size. At 46.5mm wide, 52mm lug-to-lug, and 15mm…
