SRPH23K1 takes the compact 5 Sports field platform and sharpens it with a black dial and steel mesh bracelet. The 39.4mm round stainless steel case wears neatly, while curved Hardlex crystal and LumiBrite hands and indexes keep the face clean, tough, and easy to read. Its automatic movement features manual winding, stop-seconds, day/date, and about 41 hours of reserve. Add 10 bar water resistance, magnetic resistance, flexible mesh, and a see-through case back, and you get a field-inspired automatic that feels casual, polished, and ready for everyday use. without looking overly tactical.
