The stainless-steel case of the Omega Speedmaster Professional Gemini IV Limited Edition ref. Only light micro-lines from normal wear are present, imperceptible to the touch and practically invisible on the wrist. Worth noting is a small, slightly more pronounced mark near 10 o’clock, which remains difficult to notice when the watch is worn. The steel bezel and blue aluminum tachymeter insert—signature elements of this reference—show minimal wear, barely noticeable to the naked eye.
