The Omega Speedmaster Professional Moonwatch. The name alone conjures images of lunar landings, daring astronauts, and a legacy of unparalleled horological achievement. Specifically, the Omega Men's 31130423001005 Speedmaster, a 42mm stainless steel model with a classic black dial, represents a direct lineage to those iconic timepieces that accompanied humanity's first steps on the moon. But while the heritage is undeniable, a closer examination reveals a watch that, despite its stellar pedigree, receives a somewhat mixed reception, as evidenced by its 3.2 out of 5-star rating from 27 reviewers. This article will delve deep into the intricacies of the Omega Men's 31130423001005 Speedmaster, exploring its design, functionality, historical significance, and the reasons behind its somewhat divisive rating.
A Legacy Forged in Space:
The Speedmaster's story is inseparable from its role in NASA's space program. Rigorously tested and ultimately selected over other contenders, the Speedmaster proved its resilience and accuracy in the harsh conditions of space. Its enduring presence on the wrists of astronauts during the Apollo missions cemented its status as a legend, transforming it from a simple chronograph into a symbol of human achievement and exploration. The 31130423001005 model directly reflects this heritage, inheriting the key design elements that made the original Speedmaster so successful.
The 42mm stainless steel case, a size considered classic and versatile, is robust and capable of withstanding considerable wear and tear. This robust construction is a direct descendant of the functionality demanded by the NASA testing. The iconic tachymeter bezel, a crucial tool for calculating speed, is present and correct, its black aluminum insert contrasting sharply with the polished steel of the case. The hesalite crystal, known for its superior scratch resistance compared to sapphire, adds another layer of authenticity to this faithful reproduction of the historical design. The choice of Hesalite, rather than the more modern sapphire, is a deliberate nod to the original Moonwatch and is often cited by enthusiasts as a key element of its charm and historical accuracy.
The Heart of the Matter: The Calibre 1861 Movement
Powering this iconic timepiece is the manually wound Calibre 1861 movement, a direct descendant of the calibre 321 that powered the original Moonwatch. While the 321 is a highly sought-after collector's item, the 1861 offers a worthy and more accessible alternative. It's a robust and reliable movement known for its simplicity and ease of maintenance, mirroring the practicality demanded by the original design brief. The manual winding mechanism, while requiring a daily ritual, connects the wearer more directly to the watch's mechanics, offering a tactile experience absent in many automatic movements. The exposed movement back allows for appreciation of the intricate workings within, a visual representation of the watch's mechanical heart. This transparency speaks to Omega’s commitment to upholding the legacy of the Moonwatch, even in the details.
