Its history became forever associated with space exploration when the Speedmaster Professional was selected for NASA's manned space missions, eventually accompanying astronauts during the historic Apollo 11 lunar landing in 1969. While the Speedmaster 38 represents a distinct modern collection rather than the original Moonwatch, it preserves many of the design elements that established the Speedmaster as one of the world's most recognizable mechanical chronographs.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis particular reference features a striking \u003c\/span\u003e\u003cspan\u003eblack dial with three circular chronograph registers\u003c\/span\u003e\u003cspan\u003e, creating a more traditional sporting appearance than the oval subdials found on several other Speedmaster 38 variations. Rhodium-plated hour markers and coordinating hands provide excellent contrast against the dark dial, while luminous accents enhance readability in low-light conditions. A practical date window at 6 o'clock integrates into the chronograph layout, adding everyday functionality without compromising the watch's balanced design.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSurrounding the dial is a \u003c\/span\u003e\u003cspan\u003efixed stainless steel bezel with a black aluminum tachymeter ring\u003c\/span\u003e\u003cspan\u003e, one of the defining features of the Speedmaster collection. Originally developed to calculate average speed over a known distance, the tachymeter reinforces the watch's connection to motorsport and precision timing.
