The Omega Speedmaster has a legacy deeply intertwined with space exploration, solidified by its role as the first watch worn on the moon. However, the Speedmaster family extends beyond the iconic Professional Moonwatch. One particularly compelling chapter in this rich history belongs to the Speedmaster Mark II, a watch that, while less celebrated than its lunar-conquering sibling, holds a unique place in horological history and continues to fascinate collectors today.
Somewhere in 1969, Omega introduced a bold new addition to the Speedmaster line: the Speedmaster Professional Mark II. The addition of "Professional" was sometimes omitted in marketing materials, leading to some confusion, but its lineage to the iconic Speedmaster Professional was undeniable. The "Mark" designation, in this context, doesn't signify a specific revision number in the manner of a software update. Rather, it reflects a distinct design iteration, a departure from the classic Moonwatch aesthetic while retaining the core Speedmaster spirit of robust functionality and sporty appeal. It marked a significant shift in design language, reflecting the changing tastes of the late 1960s and early 1970s.
A Bold Departure: Design and Functionality
The Speedmaster Mark II presented a striking contrast to its predecessor. While the Moonwatch remained largely unchanged, clinging to its classic, almost minimalist design, the Mark II embraced a more assertive, angular aesthetic. Its tonneau-shaped case, a departure from the Moonwatch's symmetrical round case, immediately set it apart. This unconventional shape, though initially unconventional for a chronograph, gave the watch a distinctly modern and sporty feel, reflecting the broader design trends of the era.
The dial, too, showcased a departure. Instead of the simple, highly legible layout of the Moonwatch, the Mark II featured a more complex, arguably busier, layout. The sub-dials were larger and more prominently displayed, contributing to the watch's overall bolder presence. The hands, too, were redesigned, often with a distinctive, slightly broader, and more angular shape. Many versions featured luminous indices and hands, enhancing readability in low-light conditions, a crucial feature for a watch intended for active use.
But beyond its striking design, the Mark II also boasted several functional improvements. The movement, a caliber 861, was a refined version of the legendary caliber 861 used in the Speedmaster Professional. This robust and reliable movement provided the foundation for the Mark II's accuracy and longevity. The addition of a quick-set date function, absent in the Moonwatch at the time, added to its practical appeal.
The crystal, often a hesalite acrylic, provided a degree of scratch resistance, although less than modern sapphire crystals. However, its slightly domed shape added to the watch's vintage charm and contributed to its unique character. The caseback, typically stainless steel, offered a degree of water resistance, although not to the depths achievable by modern diving watches. The overall construction reflected Omega's commitment to robust reliability, a hallmark of the Speedmaster line.
