Omega Speedmaster Chronograph with Open Heart Subdial

This item is an Omega Speedmaster chronograph wristwatch, featuring a striking black dial with three subdials, typical of a chronograph. The dial exhibits a brushed or matte finish, and the applied hour markers appear to be in a metallic, possibly silver or white gold, tone, contrasting with the dark background. The hands are also metallic. The watch has a prominent tachymeter bezel, which is black with gold-toned markings, suggesting a two-tone aesthetic or a gold-accented stainless steel construction. One of the subdials, specifically at the 9 o'clock position (or possibly the running seconds subdial), appears to be an open-heart design, revealing the intricate mechanics of the movement beneath, a distinctive and somewhat unusual feature for a Speedmaster, possibly indicating a special edition or custom modification. The case is polished stainless steel, and the watch is fitted with a matching stainless steel bracelet with a finely linked construction. The overall condition appears to be very good, with minimal visible wear on the case and bracelet, indicating it has been well-maintained. The contrast of the gold accents on the bezel against the silver-toned case and bracelet provides a sophisticated and somewhat luxurious appearance. The chronograph pushers and crown are visible on the right side of the case. The craftsmanship appears to be of high quality, consistent with the Omega brand, known for its precision and durability. The open-heart element suggests a focus on the mechanical artistry of watchmaking.
