This exquisite 1970s Longines Ultronic features a 41mm brushed and polished stainless steel tonneau-shaped case with polished flanks, stubby lugs, a chamfered edge leading to a lug-to-lug length of 44mm, and a case thickness of 10mm, ensuring a cushion-like fit on your wrist. It has a signed recessed crown on the right side and a concave slope with a domed crystal above a silver electroplated vertical brushed dial. The dial showcases applied steel arched square “Tuning Fork” shaped indexes, a framed date window at 3 o'clock, steel sword hands filled with Tritium, a vibrant red tapered second hand, the Longines motif at noon, and the “Ultronic” logo at 6 o'clock. The watch houses the Tuning Fork Longines Cal. 6312 (ESA 9162) F300 Hz movement, designed by Max Hetzel, and comes paired with its original 22mm Longines 3-link stainless steel bracelet with a signed folding clasp, complete with the original Longines presentation box, making it a highly collectible full set.
