In a fascinating exploration of horological history, hmmmcamu delves into the origins and evolution of NASA's authentic watch straps. This post highlights the meticulous journey from early Mercury program wristwear to the specialized Hook and Loop designs, shedding light on the often-overlooked accessories that accompanied astronauts into space. hmmmcamu's research provides a valuable perspective on the functional requirements and manufacturing shifts behind these iconic straps.
THE MOST AUTHENTIC NASA WATCH STRAP using original matériel made by a TRUE enthusiast ...
Originally for the Mercury program no single watch was identified as the approved time-piece and for whatever watch was worn a simple adjustable metal bracelet made by JB Champion USA Expandable Stainless Steel Mesh Bracelet ... (not frostner komfit) ... worn over the pressure suit sleeve was sufficient.
In 1964 NASA's Flight Crew Integration Division (FCID) workshops made the chronograph watchbands "in house".
1986 NASA's non-core support activities were outsourced to Boeing Aerospace Operations (BAO) , who took over manufacture and supply of the watchbands as part of a Flight Equipment Processing Contract (FEPC).
The Hook and Loop straps came in BOTH long (over spacesuit) and short lengths (inside cabin).

About the Omega Speedmaster Ref. CK2998
The Omega CK2998 is a chronograph model recognized for its robust design and functional aesthetic. It belongs to a lineage of chronographs that established a distinct visual identity for the brand, characterized by a clear and legible dial layout. This reference is notable for its early adoption of a tachymeter scale on the bezel, a feature that would become a hallmark of many subsequent sports chronographs.
This reference features a 39 mm stainless steel case, housing the manual-winding Caliber 321. This movement provides a power reserve of 45 hours. The watch is fitted with a Hesalite crystal and offers a water resistance of 60 meters. The fixed tachymeter bezel is a key design element, framing a black dial.
The CK2998 holds interest for collectors seeking early examples of Omega's chronograph development. Its design elements, including the case proportions and dial configuration, represent a significant period in the brand's history. The presence of the Caliber 321 further enhances its appeal among enthusiasts of vintage chronograph movements.
