Hey r/Watchexchange! This is the **Omega Speedmaster Professional Ref. 3597.16** is a commemorative limited edition released to honor the Apollo XII mission, part of Omega’s legendary association with NASA’s space program. Like the classic Moonwatch, it features a 42mm stainless steel case, Hesalite crystal, and is powered by the manual-winding Caliber 1861, the same movement that has flown to the Moon. What makes the 3597.16 truly special is the colorful Apollo XII mission patch embedded in the 9 o’clock subdial, displaying an image of the Moon and the Earth in vibrant blue and gold tones, along with the names of the mission crew: Conrad, Gordon, and Bean. The dial retains the iconic black matte finish with white baton hour markers and hands, giving it the classic Speedmaster look, while the tachymeter bezel adds functionality and vintage appeal. This reference was part of the “Missions” collection Omega released in the late ‘90s, which included special editions for each Apollo mission. Often sought after by collectors, the 3597.16 is more than a watch — it’s a wearable tribute to a pivotal moment in human spaceflight history. — **Year:** Can check upon request **Physical condition:** Preowned, please refer to the photos for the most accurate depiction of the condition **Mechanical Condition:** Running well **Box and Papers:** Watch and Papers **Price: $7,500**. **Payment methods:** Zelle, Bank Wire, Crypto (USDT + 3%).
